/**
* A JDBC driver which is a facade that delegates to one or more real underlying
* JDBC drivers. The driver will spy on any other JDBC driver that is loaded,
* simply by prepending <code>jdbc:log4</code> to the normal jdbc driver URL
* used by any other JDBC driver. The driver, by default, also loads several
* well known drivers at class load time, so that this driver can be
* "dropped in" to any Java program that uses these drivers without making any
* code changes.
* <p/>
* The well known driver classes that are loaded are:
* <p/>
* <p/>
* <code>
* <ul>
* <li>oracle.jdbc.driver.OracleDriver</li>
* <li>com.sybase.jdbc2.jdbc.SybDriver</li>
* <li>net.sourceforge.jtds.jdbc.Driver</li>
* <li>com.microsoft.jdbc.sqlserver.SQLServerDriver</li>
* <li>com.microsoft.sqlserver.jdbc.SQLServerDriver</li>
* <li>weblogic.jdbc.sqlserver.SQLServerDriver</li>
* <li>com.informix.jdbc.IfxDriver</li>
* <li>org.apache.derby.jdbc.ClientDriver</li>
* <li>org.apache.derby.jdbc.EmbeddedDriver</li>
* <li>com.mysql.jdbc.Driver</li>
* <li>org.postgresql.Driver</li>
* <li>org.hsqldb.jdbcDriver</li>
* <li>org.h2.Driver</li>
* </ul>
* </code>
* <p/>
* <p/>
* Additional drivers can be set via a property: <b>log4jdbc.drivers</b>
* This can be either a single driver class name or a list of comma separated
* driver class names.
* <p/>
* The autoloading behavior can be disabled by setting a property:
* <b>log4jdbc.auto.load.popular.drivers</b> to false. If that is done, then
* the only drivers that log4jdbc will attempt to load are the ones specified
* in <b>log4jdbc.drivers</b>.
* <p/>
* If any of the above driver classes cannot be loaded, the driver continues on
* without failing.
* <p/>
* Note that the <code>getMajorVersion</code>, <code>getMinorVersion</code> and
* <code>jdbcCompliant</code> method calls attempt to delegate to the last
* underlying driver requested through any other call that accepts a JDBC URL.
* <p/>
* This can cause unexpected behavior in certain circumstances. For example,
* if one of these 3 methods is called before any underlying driver has been
* established, then they will return default values that might not be correct
* in all situations. Similarly, if this spy driver is used to spy on more than
* one underlying driver concurrently, the values returned by these 3 method
* calls may change depending on what the last underlying driver used was at the
* time. This will not usually be a problem, since the driver is retrieved by
* it's URL from the DriverManager in the first place (thus establishing an
* underlying real driver), and in most applications their is only one database.

/**
* @fileoverview
* some functions for browser-side pretty printing of code contained in html.
*
* <p>
* For a fairly comprehensive set of languages see the
* <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
* file that came with this source. At a minimum, the lexer should work on a
* number of languages including C and friends, Java, Python, Bash, SQL, HTML,
* XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk
* and a subset of Perl, but, because of commenting conventions, doesn't work on
* Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
* <p>
* Usage: <ol>
* <li> include this source file in an html page via
* {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
* <li> define style rules. See the example page for examples.
* <li> mark the {@code <pre>} and {@code <code>} tags in your source with
* {@code class=prettyprint.}
* You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
* printer needs to do more substantial DOM manipulations to support that, so
* some css styles may not be preserved.
* </ol>
* That's it. I wanted to keep the API as simple as possible, so there's no
* need to specify which language the code is in, but if you wish, you can add
* another class to the {@code <pre>} or {@code <code>} element to specify the
* language, as in {@code <pre class="prettyprint lang-java">}. Any class that
* starts with "lang-" followed by a file extension, specifies the file type.
* See the "lang-*.js" files in this directory for code that implements
* per-language file handlers.
* <p>
* Change log:<br>
* cbeust, 2006/08/22
* <blockquote>
* Java annotations (start with "@") are now captured as literals ("lit")
* </blockquote>

* constant like PR_PLAIN. index_n-1 <= index_n, and style_n-1 applies to
* all characters in sourceCode[index_n-1:index_n].
*
* The stylePatterns is a list whose elements have the form
* [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
*
* Style is a style constant like PR_PLAIN, or can be a string of the
* form 'lang-FOO', where FOO is a language extension describing the
* language of the portion of the token in $1 after pattern executes.
* E.g., if style is 'lang-lisp', and group 1 contains the text
* '(hello (world))', then that portion of the token will be passed to the
* registered lisp handler for formatting.
* The text before and after group 1 will be restyled using this decorator
* so decorators should take care that this doesn't result in infinite
* recursion. For example, the HTML lexer rule for SCRIPT elements looks
* something like ['lang-js', /<[s]cript>(.+?)<\/script>/]. This may match
* '<script>foo()<\/script>', which would cause the current decorator to
* be called with '<script>' which would not match the same rule since
* group 1 must not be empty, so it would be instead styled as PR_TAG by
* the generic tag rule. The handler registered for the 'js' extension would
* then be called with 'foo()', and finally, the current decorator would
* be called with '<\/script>' which would not match the original rule and
* so the generic tag rule would identify it as a tag.
*
* Pattern must only match prefixes, and if it matches a prefix, then that
* match is considered a token with the same style.
*
* Context is applied to the last non-whitespace, non-comment token
* recognized.
*
* Shortcut is an optional string of characters, any of which, if the first
* character, gurantee that this pattern and only this pattern matches.
*
* @param {Array} shortcutStylePatterns patterns that always start with

/**
* @ngdoc overview
* @name ngResource
* @description
*/
/**
* @ngdoc object
* @name ngResource.$resource
* @requires $http
*
* @description
* A factory which creates a resource object that lets you interact with
* [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
*
* The returned resource object has action methods which provide high-level behaviors without
* the need to interact with the low level {@link ng.$http $http} service.
*
* @param {string} url A parameterized URL template with parameters prefixed by `:` as in
* `/user/:username`.
*
* @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
* `actions` methods.
*
* Each key value in the parameter object is first bound to url template if present and then any
* excess keys are appended to the url search query after the `?`.
*
* Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
* URL `/path/greet?salutation=Hello`.
*
* If the parameter value is prefixed with `@` then the value of that parameter is extracted from
* the data object (useful for non-GET operations).
*
* @param {Object.<Object>=} actions Hash with declaration of custom action that should extend the
* default set of resource actions. The declaration should be created in the following format:
*
* {action1: {method:?, params:?, isArray:?},
* action2: {method:?, params:?, isArray:?},
* ...}
*
* Where:
*
* - `action` – {string} – The name of action. This name becomes the name of the method on your
* resource object.
* - `method` – {string} – HTTP request method. Valid methods are: `GET`, `POST`, `PUT`, `DELETE`,
* and `JSONP`
* - `params` – {object=} – Optional set of pre-bound parameters for this action.
* - isArray – {boolean=} – If true then the returned object for this action is an array, see
* `returns` section.
*
* @returns {Object} A resource "class" object with methods for the default set of resource actions
* optionally extended with custom `actions`. The default set contains these actions:
*
* { 'get': {method:'GET'},
* 'save': {method:'POST'},
* 'query': {method:'GET', isArray:true},
* 'remove': {method:'DELETE'},
* 'delete': {method:'DELETE'} };
*
* Calling these methods invoke an {@link ng.$http} with the specified http method,
* destination and parameters. When the data is returned from the server then the object is an
* instance of the resource class `save`, `remove` and `delete` actions are available on it as
* methods with the `$` prefix. This allows you to easily perform CRUD operations (create, read,
* update, delete) on server-side data like this:
* <pre>
var User = $resource('/user/:userId', {userId:'@id'});
var user = User.get({userId:123}, function() {
user.abc = true;
user.$save();
});
</pre>
*
* It is important to realize that invoking a $resource object method immediately returns an
* empty reference (object or array depending on `isArray`). Once the data is returned from the
* server the existing reference is populated with the actual data. This is a useful trick since
* usually the resource is assigned to a model which is then rendered by the view. Having an empty
* object results in no rendering, once the data arrives from the server then the object is
* populated with the data and the view automatically re-renders itself showing the new data. This
* means that in most case one never has to write a callback function for the action methods.
*
* The action methods on the class object or instance object can be invoked with the following
* parameters:
*
* - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
* - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
* - non-GET instance actions: `instance.$action([parameters], [success], [error])`
*
*
* @example
*
* # Credit card resource
*
* <pre>
// Define CreditCard class
var CreditCard = $resource('/user/:userId/card/:cardId',
{userId:123, cardId:'@id'}, {
charge: {method:'POST', params:{charge:true}}
});
// We can retrieve a collection from the server
var cards = CreditCard.query(function() {
// GET: /user/123/card
// server returns: [ {id:456, number:'1234', name:'Smith'} ];
var card = cards[0];
// each item is an instance of CreditCard
expect(card instanceof CreditCard).toEqual(true);
card.name = "J. Smith";
// non GET methods are mapped onto the instances
card.$save();
// POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
// server returns: {id:456, number:'1234', name: 'J. Smith'};
// our custom method is mapped as well.
card.$charge({amount:9.99});
// POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
});
// we can create an instance as well
var newCard = new CreditCard({number:'0123'});
newCard.name = "Mike Smith";
newCard.$save();
// POST: /user/123/card {number:'0123', name:'Mike Smith'}
// server returns: {id:789, number:'01234', name: 'Mike Smith'};
expect(newCard.id).toEqual(789);
* </pre>
*
* The object returned from this function execution is a resource "class" which has "static" method
* for each action in the definition.
*
* Calling these methods invoke `$http` on the `url` template with the given `method` and `params`.
* When the data is returned from the server then the object is an instance of the resource type and
* all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
* operations (create, read, update, delete) on server-side data.
<pre>
var User = $resource('/user/:userId', {userId:'@id'});
var user = User.get({userId:123}, function() {
user.abc = true;
user.$save();
});
</pre>
*
* It's worth noting that the success callback for `get`, `query` and other method gets passed
* in the response that came from the server as well as $http header getter function, so one
* could rewrite the above example and get access to http headers as:
*
<pre>
var User = $resource('/user/:userId', {userId:'@id'});
User.get({userId:123}, function(u, getResponseHeaders){
u.abc = true;
u.$save(function(u, putResponseHeaders) {
//u => saved user object
//putResponseHeaders => $http header getter
});
});
</pre>
* # Buzz client
Let's look at what a buzz client created with the `$resource` service looks like:

<doc:source jsfiddle="false">

this.userId = 'googlebuzz';

);
}
BuzzController.prototype = {
fetch: function() {
this.activities = this.Activity.get({userId:this.userId});
},
expandReplies: function(activity) {
activity.replies = this.Activity.replies({userId:this.userId, activityId:activity.id});
}
};
BuzzController.$inject = ['$resource'];

/**
* @ngdoc function
* @name angular.element
* @function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
* `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
* jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
* implementation (commonly referred to as jqLite).
*
* Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
* event fired.
*
* jqLite is a tiny, API-compatible subset of jQuery that allows
* Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
* within a very small footprint, so only a subset of the jQuery API - methods, arguments and
* invocation styles - are supported.
*
* Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
* raw DOM references.
*
* ## Angular's jQuery lite provides the following methods:
*
* - [addClass()](http://api.jquery.com/addClass/)
* - [after()](http://api.jquery.com/after/)
* - [append()](http://api.jquery.com/append/)
* - [attr()](http://api.jquery.com/attr/)
* - [bind()](http://api.jquery.com/bind/)
* - [children()](http://api.jquery.com/children/)
* - [clone()](http://api.jquery.com/clone/)
* - [contents()](http://api.jquery.com/contents/)
* - [css()](http://api.jquery.com/css/)
* - [data()](http://api.jquery.com/data/)
* - [eq()](http://api.jquery.com/eq/)
* - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name.
* - [hasClass()](http://api.jquery.com/hasClass/)
* - [html()](http://api.jquery.com/html/)
* - [next()](http://api.jquery.com/next/)
* - [parent()](http://api.jquery.com/parent/)
* - [prepend()](http://api.jquery.com/prepend/)
* - [prop()](http://api.jquery.com/prop/)
* - [ready()](http://api.jquery.com/ready/)
* - [remove()](http://api.jquery.com/remove/)
* - [removeAttr()](http://api.jquery.com/removeAttr/)
* - [removeClass()](http://api.jquery.com/removeClass/)
* - [removeData()](http://api.jquery.com/removeData/)
* - [replaceWith()](http://api.jquery.com/replaceWith/)
* - [text()](http://api.jquery.com/text/)
* - [toggleClass()](http://api.jquery.com/toggleClass/)
* - [unbind()](http://api.jquery.com/unbind/)
* - [val()](http://api.jquery.com/val/)
* - [wrap()](http://api.jquery.com/wrap/)
*
* ## In addtion to the above, Angular privides an additional method to both jQuery and jQuery lite:
*
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
* retrieves controller associated with the `ngController` directive. If `name` is provided as
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
* `'ngModel'`).
* - `injector()` - retrieves the injector of the current element or its parent.
* - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
* element or its parent.
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
* parent element is reached.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.

* # Injection Function Annotation
*
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
* following ways are all valid way of annotating function with injection arguments and are equivalent.
*
* <pre>
* // inferred (only works if code not minified/obfuscated)
* $inject.invoke(function(serviceA){});
*
* // annotated
* function explicit(serviceA) {};
* explicit.$inject = ['serviceA'];
* $inject.invoke(explicit);
*
* // inline
* $inject.invoke(['serviceA', function(serviceA){}]);
* </pre>
*
* ## Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition can then be
* parsed and the function arguments can be extracted. *NOTE:* This does not work with minification, and obfuscation
* tools since these tools change the argument names.
*
* ## `$inject` Annotation
* By adding a `$inject` property onto a function the injection parameters can be specified.
*
* ## Inline
* As an array of injection names, where the last item in the array is the function to call.

/**
* @ngdoc method
* @name AUTO.$injector#annotate
* @methodOf AUTO.$injector
*
* @description
* Returns an array of service names which the function is requesting for injection. This API is used by the injector
* to determine which services need to be injected into the function when the function is invoked. There are three
* ways in which the function can be annotated with the needed dependencies.
*
* # Argument names
*
* The simplest form is to extract the dependencies from the arguments of the function. This is done by converting
* the function into a string using `toString()` method and extracting the argument names.
* <pre>
* // Given
* function MyController($scope, $route) {
* // ...
* }
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* </pre>
*
* This method does not work with code minfication / obfuscation. For this reason the following annotation strategies
* are supported.
*
* # The `$injector` property
*
* If a function has an `$inject` property and its value is an array of strings, then the strings represent names of
* services to be injected into the function.
* <pre>
* // Given
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
* // ...
* }
* // Define function dependencies
* MyController.$inject = ['$scope', '$route'];
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* </pre>
*
* # The array notation
*
* It is often desirable to inline Injected functions and that's when setting the `$inject` property is very
* inconvenient. In these situations using the array notation to specify the dependencies in a way that survives
* minification is a better choice:
*
* <pre>
* // We wish to write this (not minification / obfuscation safe)
* injector.invoke(function($compile, $rootScope) {
* // ...
* });
*
* // We are forced to write break inlining
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
* // ...
* };
* tmpFn.$inject = ['$compile', '$rootScope'];
* injector.invoke(tempFn);
*
* // To better support inline function the inline annotation is supported
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
* // ...
* }]);
*
* // Therefore
* expect(injector.annotate(
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
* ).toEqual(['$compile', '$rootScope']);
* </pre>
*
* @param {function|Array.<string|Function>} fn Function for which dependent service names need to be retrieved as described
* above.
*
* @returns {Array.<string>} The names of the services which the function requires.

* @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
* @param {number} maxPriority only apply directives lower then given priority (Only effects the
* root element(s), not their children)
* @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
* called as: <br> `cloneAttachFn(clonedElement, scope)` where:
*
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
* * `scope` - is the current scope with which the linking function is working with.
*
* Calling the linking function returns the element of the template. It is either the original element
* passed in, or the clone of the element if the `cloneAttachFn` is provided.
*
* After linking the view is not updated until after a call to $digest which typically is done by
* Angular automatically.
*
* If you need access to the bound view, there are two ways to do it:
*
* - If you are not asking the linking function to clone the template, create the DOM element(s)
* before you send them to the compiler and keep this reference around.
* <pre>
* var element = $compile('<p>{{total}}</p>')(scope);
* </pre>
*
* - if on the other hand, you need the element to be cloned, the view reference from the original
* example would not point to the clone, but rather to the original template that was cloned. In
* this case, you can access the clone via the cloneAttachFn:
* <pre>
* var templateHTML = angular.element('<p>{{total}}</p>'),
* scope = ....;
*
* var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
* //attach the clone to DOM document at the right place
* });
*
* //now we have reference to the cloned DOM via `clone`
* </pre>
*
*
* For information on how the compiler works, see the
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

* @ngdoc service

*
* @description
* A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
*
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
* interface for interacting with an object that represents the result of an action that is
* performed asynchronously, and may or may not be finished at any given point in time.
*
* From the perspective of dealing with error handling, deferred and promise apis are to
* asynchronous programing what `try`, `catch` and `throw` keywords are to synchronous programing.
*
* <pre>
* // for the purpose of this example let's assume that variables `$q` and `scope` are
* // available in the current lexical scope (they could have been injected or passed in).
*
* function asyncGreet(name) {
* var deferred = $q.defer();
*
* setTimeout(function() {
* // since this fn executes async in a future turn of the event loop, we need to wrap
* // our code into an $apply call so that the model changes are properly observed.
* scope.$apply(function() {
* if (okToGreet(name)) {
* deferred.resolve('Hello, ' + name + '!');
* } else {
* deferred.reject('Greeting ' + name + ' is not allowed.');
* }
* });
* }, 1000);
*
* return deferred.promise;
* }
*
* var promise = asyncGreet('Robin Hood');
* promise.then(function(greeting) {
* alert('Success: ' + greeting);
* }, function(reason) {
* alert('Failed: ' + reason);
* );
* </pre>
*
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff
* comes in the way of
* [guarantees that promise and deferred apis make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md).
*
* Additionally the promise api allows for composition that is very hard to do with the
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
* section on serial or parallel joining of promises.
*
*
* # The Deferred API
*
* A new instance of deferred is constructed by calling `$q.defer()`.
*
* The purpose of the deferred object is to expose the associated Promise instance as well as apis
* that can be used for signaling the successful or unsuccessful completion of the task.
*
* **Methods**
*
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
* constructed via `$q.reject`, the promise will be rejected instead.
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
* resolving it with a rejection constructed via `$q.reject`.
*
* **Properties**
*
* - promise – `{Promise}` – promise object associated with this deferred.
*
*
* # The Promise API
*
* A new promise instance is created when a deferred instance is created and can be retrieved by
* calling `deferred.promise`.
*
* The purpose of the promise object is to allow for interested parties to get access to the result
* of the deferred task when it completes.
*
* **Methods**
*
* - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved
* or rejected calls one of the success or error callbacks asynchronously as soon as the result
* is available. The callbacks are called with a single argument the result or rejection reason.
*
* This method *returns a new promise* which is resolved or rejected via the return value of the
* `successCallback` or `errorCallback`.
*
*
* # Chaining promises
*
* Because calling `then` api of a promise returns a new derived promise, it is easily possible
* to create a chain of promises:
*
* <pre>
* promiseB = promiseA.then(function(result) {
* return result + 1;
* });
*
* // promiseB will be resolved immediately after promiseA is resolved and it's value will be
* // the result of promiseA incremented by 1
* </pre>
*
* It is possible to create chains of any length and since a promise can be resolved with another
* promise (which will defer its resolution further), it is possible to pause/defer resolution of
* the promises at any point in the chain. This makes it possible to implement powerful apis like
* $http's response interceptors.
*
*
* # Differences between Kris Kowal's Q and $q
*
* There are three main differences:
*
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
* mechanism in angular, which means faster propagation of resolution or rejection into your
* models and avoiding unnecessary browser repaints, which would result in flickering UI.
* - $q promises are recognized by the templating engine in angular, which means that in templates
* you can treat promises attached to a scope as if they were the resulting values.
* - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains
* all the important functionality needed for common async tasks.

* - `templateUrl` – `{string=}` – path to an html template that should be used by

* DESIGN NOTES
*
* The design decisions behind the scope ware heavily favored for speed and memory consumption.
*
* The typical use of scope is to watch the expressions, which most of the time return the same
* value as last time so we optimize the operation.
*
* Closures construction is expensive from speed as well as memory:
* - no closures, instead ups prototypical inheritance for API
* - Internal state needs to be stored on scope directly, which means that private state is
* exposed as $$____ properties
*
* Loop operations are optimized by using while(count--) { ... }
* - this means that in order to keep the same order of execution as addition we have to add
* items to the array at the begging (shift) instead of at the end (push)
*
* Child scopes are created and removed often
* - Using array would be slow since inserts in meddle are expensive so we use linked list
*
* There are few watches then a lot of observers. This is why you don't want the observer to be
* implemented in the same way as watch. Watch requires return of initialization function which
* are expensive to construct.

* @description
* Registers a `listener` callback to be executed whenever the `watchExpression` changes.
*
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest $digest()} and
* should return the value which will be watched. (Since {@link ng.$rootScope.Scope#$digest $digest()}
* reruns when it detects changes the `watchExpression` can execute multiple times per
* {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
* - The `listener` is called only when the value from the current `watchExpression` and the
* previous call to `watchExpression' are not equal (with the exception of the initial run
* see below). The inequality is determined according to
* {@link angular.equals} function. To save the value of the object for later comparison
* {@link angular.copy} function is used. It also means that watching complex options will
* have adverse memory and performance implications.
* - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
* is achieved by rerunning the watchers until no changes are detected. The rerun iteration
* limit is 100 to prevent infinity loop deadlock.
*
*
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
* you can register an `watchExpression` function with no `listener`. (Since `watchExpression`,
* can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a change is
* detected, be prepared for multiple calls to your listener.)
*
* After a watcher is registered with the scope, the `listener` fn is called asynchronously
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
* watcher. In rare cases, this is undesirable because the listener is called when the result
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
* listener was called due to initialization.
*
*
* # Example
* <pre>
// let's assume that scope was dependency injected as the $rootScope
var scope = $rootScope;
scope.name = 'misko';
scope.counter = 0;
expect(scope.counter).toEqual(0);

* @param {(function()|string)=} listener Callback called whenever the return value of

* @ngdoc function
* @name ng.$http
* @requires $httpBacked
* @requires $browser
* @requires $cacheFactory
* @requires $rootScope
* @requires $q
* @requires $injector
*
* @description
* The `$http` service is a core Angular service that facilitates communication with the remote
* HTTP servers via browser's {@link https://developer.mozilla.org/en/xmlhttprequest
* XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
*
* For unit testing applications that use `$http` service, see
* {@link ngMock.$httpBackend $httpBackend mock}.
*
* For a higher level of abstraction, please check out the {@link ngResource.$resource
* $resource} service.
*
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
* the $q service. While for simple usage patters this doesn't matter much, for advanced usage,
* it is important to familiarize yourself with these apis and guarantees they provide.
*
*
* # General usage
* The `$http` service is a function which takes a single argument — a configuration object —
* that is used to generate an http request and returns a {@link ng.$q promise}
* with two $http specific methods: `success` and `error`.
*
* <pre>
* $http({method: 'GET', url: '/someUrl'}).
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // called asynchronously if an error occurs
* // or server returns response with status
* // code outside of the <200, 400) range
* });
* </pre>
*
* Since the returned value of calling the $http function is a Promise object, you can also use
* the `then` method to register callbacks, and these callbacks will receive a single argument –
* an object representing the response. See the api signature and type info below for more
* details.
*
*
* # Shortcut methods
*
* Since all invocation of the $http service require definition of the http method and url and
* POST and PUT requests require response body/data to be provided as well, shortcut methods
* were created to simplify using the api:
*
* <pre>
* $http.get('/someUrl').success(successCallback);
* $http.post('/someUrl', data).success(successCallback);
* </pre>
*
* Complete list of shortcut methods:
*
* - {@link ng.$http#get $http.get}
* - {@link ng.$http#head $http.head}
* - {@link ng.$http#post $http.post}
* - {@link ng.$http#put $http.put}
* - {@link ng.$http#delete $http.delete}
* - {@link ng.$http#jsonp $http.jsonp}
*
*
* # Setting HTTP Headers
*
* The $http service will automatically add certain http headers to all requests. These defaults
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
* object, which currently contains this default configuration:
*
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
* - `Accept: application/json, text/plain, * / *`
* - `X-Requested-With: XMLHttpRequest`
* - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests)
* - `Content-Type: application/json`
* - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests)
* - `Content-Type: application/json`
*
* To add or overwrite these defaults, simply add or remove a property from this configuration
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
* with name equal to the lower-cased http method name, e.g.
* `$httpProvider.defaults.headers.get['My-Header']='value'`.
*
* Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar
* fassion as described above.
*
*
* # Transforming Requests and Responses
*
* Both requests and responses can be transformed using transform functions. By default, Angular
* applies these transformations:
*
* Request transformations:
*
* - if the `data` property of the request config object contains an object, serialize it into
* JSON format.
*
* Response transformations:
*
* - if XSRF prefix is detected, strip it (see Security Considerations section below)
* - if json response is detected, deserialize it using a JSON parser
*
* To override these transformation locally, specify transform functions as `transformRequest`
* and/or `transformResponse` properties of the config object. To globally override the default
* transforms, override the `$httpProvider.defaults.transformRequest` and
* `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`.
*
*
* # Caching
*
* To enable caching set the configuration property `cache` to `true`. When the cache is
* enabled, `$http` stores the response from the server in local cache. Next time the
* response is served from the cache without sending a request to the server.
*
* Note that even if the response is served from cache, delivery of the data is asynchronous in
* the same way that real requests are.
*
* If there are multiple GET requests for the same url that should be cached using the same
* cache, but the cache is not populated yet, only one request to the server will be made and
* the remaining requests will be fulfilled using the response for the first request.
*
*
* # Response interceptors
*
* Before you start creating interceptors, be sure to understand the
* {@link ng.$q $q and deferred/promise APIs}.
*
* For purposes of global error handling, authentication or any kind of synchronous or
* asynchronous preprocessing of received responses, it is desirable to be able to intercept
* responses for http requests before they are handed over to the application code that
* initiated these requests. The response interceptors leverage the {@link ng.$q
* promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
*
* The interceptors are service factories that are registered with the $httpProvider by
* adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
* injected with dependencies (if specified) and returns the interceptor — a function that
* takes a {@link ng.$q promise} and returns the original or a new promise.
*
* <pre>
* // register the interceptor as a service
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
* return function(promise) {
* return promise.then(function(response) {
* // do something on success
* }, function(response) {
* // do something on error
* if (canRecover(response)) {
* return responseOrNewPromise
* }
* return $q.reject(response);
* });
* }
* });
*
* $httpProvider.responseInterceptors.push('myHttpInterceptor');
*
*
* // register the interceptor via an anonymous factory
* $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
* return function(promise) {
* // same as above
* }
* });
* </pre>
*
*
* # Security Considerations
*
* When designing web applications, consider security threats from:
*
* - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability}
* - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
*
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
* pre-configured with strategies that address these issues, but for this to work backend server
* cooperation is required.
*
* ## JSON Vulnerability Protection
*
* A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability} allows third party web-site to turn your JSON resource URL into
* {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
* Angular will automatically strip the prefix before processing it as JSON.
*
* For example if your server needs to return:
* <pre>
* ['one','two']
* </pre>
*
* which is vulnerable to attack, your server can return:
* <pre>
* )]}',
* ['one','two']
* </pre>
*
* Angular will strip the prefix, before processing the JSON.
*
*
* ## Cross Site Request Forgery (XSRF) Protection
*
* {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
* an unauthorized site can gain your user's private data. Angular provides following mechanism
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
* called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
* runs on your domain could read the cookie, your server can be assured that the XHR came from
* JavaScript running on your domain.
*
* To take advantage of this, your server needs to set a token in a JavaScript readable session
* cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the

*
*
* @param {object} config Object describing the request to be made and how it should be
* processed. The object has following properties:
*
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned to
* `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified.
* - **data** – `{string|Object}` – Data to be sent as the request message data.
* - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server.
* - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* request body and headers and returns its transformed (typically serialized) version.
* - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* response body and headers and returns its transformed (typically deserialized) version.
* - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
* GET request, otherwise if a cache instance built with
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
* caching.
* - **timeout** – `{number}` – timeout in milliseconds.
* - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
* XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
* requests with credentials} for more information.
*
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
* standard `then` method and two http specific methods: `success` and `error`. The `then`
* method takes two arguments a success and an error callback which will be called with a
* response object. The `success` and `error` methods take a single argument - a function that
* will be called when the request succeeds or fails respectively. The arguments passed into
* these functions are destructured representation of the response object passed into the
* `then` method. The response object has these properties:
*
* - **data** – `{string|Object}` – The response body transformed with the transform functions.
* - **status** – `{number}` – HTTP status code of the response.
* - **headers** – `{function([headerName])}` – Header getter function.
* - **config** – `{Object}` – The configuration object that was used to generate the request.
*
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
* requests. This is primarily meant to be used for debugging purposes.
*

* @ngdoc filter
* @name ng.filter:filter
* @function
*
* @description
* Selects a subset of items from `array` and returns it as a new array.
*
* Note: This function is used to augment the `Array` type in Angular expressions. See
* {@link ng.$filter} for more information about Angular arrays.
*
* @param {Array} array The source array.
* @param {string|Object|function()} expression The predicate to be used for selecting items from
* `array`.
*
* Can be one of:
*
* - `string`: Predicate that results in a substring match using the value of `expression`
* string. All strings or objects with string properties in `array` that contain this string
* will be returned. The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
* which have property `name` containing "M" and property `phone` containing "1". A special
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any
* property of the object. That's equivalent to the simple substring match with a `string`
* as described above.
*
* - `function`: A predicate function can be used to write arbitrary filters. The function is
* called for each element of `array`. The final result is an array of those elements that
* the predicate returned true for.

* Formats `date` to a string based on the requested `format`.
*
* `format` string can be composed of the following elements:
*
* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
* * `'MMMM'`: Month in year (January-December)
* * `'MMM'`: Month in year (Jan-Dec)
* * `'MM'`: Month in year, padded (01-12)
* * `'M'`: Month in year (1-12)
* * `'dd'`: Day in month, padded (01-31)
* * `'d'`: Day in month (1-31)
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
* * `'EEE'`: Day in Week, (Sun-Sat)
* * `'HH'`: Hour in day, padded (00-23)
* * `'H'`: Hour in day (0-23)
* * `'hh'`: Hour in am/pm, padded (01-12)
* * `'h'`: Hour in am/pm, (1-12)
* * `'mm'`: Minute in hour, padded (00-59)
* * `'m'`: Minute in hour (0-59)
* * `'ss'`: Second in minute, padded (00-59)
* * `'s'`: Second in minute (0-59)
* * `'a'`: am/pm marker
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-1200)
*
* `format` string can also be one of the following predefined
* {@link guide/i18n localizable formats}:
*
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
* (e.g. Sep 3, 2010 12:05:08 pm)
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 pm)
* * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US locale
* (e.g. Friday, September 3, 2010)
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
*
* `format` string can contain literal values. These need to be quoted with single quotes (e.g.
* `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
* (e.g. `"h o''clock"`).
*
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and it's
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ).
* @param {string=} format Formatting rules (see Description). If not specified,

/**

*
* @description
* Directive that instantiates
* {@link ng.directive:form.FormController FormController}.
*
* If `name` attribute is specified, the form controller is published onto the current scope under
* this name.
*
* # Alias: {@link ng.directive:ngForm `ngForm`}
*
* In angular forms can be nested. This means that the outer form is valid when all of the child
* forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this
* reason angular provides {@link ng.directive:ngForm `ngForm`} alias
* which behaves identical to `<form>` but allows form nesting.
*
*
* # CSS classes
* - `ng-valid` Is set if the form is valid.
* - `ng-invalid` Is set if the form is invalid.
* - `ng-pristine` Is set if the form is pristine.
* - `ng-dirty` Is set if the form is dirty.
*
*
* # Submitting a form and preventing default action
*
* Since the role of forms in client-side Angular applications is different than in classical
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full
* page reload that sends the data to the server. Instead some javascript logic should be triggered
* to handle the form submission in application specific way.
*
* For this reason, Angular prevents the default action (form submission to the server) unless the
* `<form>` element has an `action` attribute specified.
*
* You can use one of the following two ways to specify what javascript method should be called when
* a form is submitted:
*
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
* - {@link ng.directive:ngClick ngClick} directive on the first
* button or input field of type submit (input[type=submit])
*
* To prevent double execution of the handler, use only one of ngSubmit or ngClick directives. This
* is because of the following form submission rules coming from the html spec:
*
* - If a form has only one input field then hitting enter in this field triggers form submit
* (`ngSubmit`)
* - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter
* doesn't trigger submit
* - if a form has one or more input fields and one or more buttons or input[type=submit] then
* hitting enter in any of the input fields will trigger the click handler on the *first* button or
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
*
* @param {string=} name Name of the form. If specified, the form controller will be published into
* related scope, under this name.

* `NgModelController` provides API for the `ng-model` directive. The controller contains
* services for data-binding, validation, CSS update, value formatting and parsing. It
* specifically does not contain any logic which deals with DOM rendering or listening to
* DOM events. The `NgModelController` is meant to be extended by other directives where, the
* directive provides DOM manipulation and the `NgModelController` provides the data-binding.
*
* This example shows how to use `NgModelController` with a custom control to achieve
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
* collaborate together to achieve the desired result.
*
* <example module="customControl">

[contenteditable] {
border: 1px solid black;
background-color: white;
min-height: 20px;

.ng-invalid {

}
</file>
<file name="script.js">
angular.module('customControl', []).

return {
restrict: 'A', // only activate on element attribute
require: '?ngModel', // get a hold of NgModelController

if(!ngModel) return; // do nothing if no ng-model
// Specify how UI should be updated

};
// Listen for change events to enable binding
element.bind('blur keyup change', function() {

* @description
* Is directive that tells Angular to do two-way data binding. It works together with `input`,

*
* `ngModel` is responsible for:
*
* - binding the view into the model, which other directives such as `input`, `textarea` or `select`
* require,
* - providing validation behavior (i.e. required, number, email, url),
* - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
* - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
* - register the control with parent {@link ng.directive:form form}.
*
* For basic examples, how to use `ngModel`, see:
*
* - {@link ng.directive:input input}
* - {@link ng.directive:input.text text}
* - {@link ng.directive:input.checkbox checkbox}
* - {@link ng.directive:input.radio radio}
* - {@link ng.directive:input.number number}

/**
* @ngdoc directive
* @name ng.directive:ngBind
*
* @description
* The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
* with the value of a given expression, and to update the text content when the value of that
* expression changes.
*
* Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
* `{{ expression }}` which is similar but less verbose.
*
* Once scenario in which the use of `ngBind` is prefered over `{{ expression }}` binding is when
* it's desirable to put bindings into template that is momentarily displayed by the browser in its
* raw state before Angular compiles it. Since `ngBind` is an element attribute, it makes the
* bindings invisible to the user while the page is loading.
*
* An alternative solution to this problem would be using the
* {@link ng.directive:ngCloak ngCloak} directive.

*
* @description
* The `ngCloak` directive is used to prevent the Angular html template from being briefly
* displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
* directive to avoid the undesirable flicker effect caused by the html template display.
*
* The directive can be applied to the `<body>` element, but typically a fine-grained application is
* prefered in order to benefit from progressive rendering of the browser view.
*
* `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and
* `angular.min.js` files. Following is the css rule:
*
* <pre>
* [ng\:cloak], [ng-cloak], .ng-cloak {
* display: none;
* }
* </pre>
*
* When this css rule is loaded by the browser, all html elements (including their children) that
* are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
* during the compilation of the template it deletes the `ngCloak` element attribute, which
* makes the compiled element visible.
*
* For the best result, `angular.js` script must be loaded in the head section of the html file;
* alternatively, the css rule (above) must be included in the external stylesheet of the
* application.
*
* Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
* cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
* class `ngCloak` in addition to `ngCloak` directive as shown in the example below.

* @example

/**
* @ngdoc directive

*
* @description
* The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular
* supports the principles behind the Model-View-Controller design pattern.
*
* MVC components in angular:
*
* * Model — The Model is data in scope properties; scopes are attached to the DOM.
* * View — The template (HTML with data bindings) is rendered into the View.
* * Controller — The `ngController` directive specifies a Controller class; the class has
* methods that typically express the business logic behind the application.
*
* Note that an alternative way to define controllers is via the `{@link ng.$route}`
* service.
*
* @element ANY
* @scope
* @param {expression} ngController Name of a globally accessible constructor function or an
* {@link guide/expression expression} that on the current scope evaluates to a
* constructor function.
*
* @example
* Here is a simple form for editing user contact information. Adding, removing, clearing, and
* greeting are methods declared on the controller (see source tab). These methods can
* easily be called from the angular markup. Notice that the scope becomes the `this` for the
* controller's instance. This allows for easy access to the view data from the controller. Also
* notice that any changes to the data are automatically reflected in the View without the need
* for a manual update.

/**
* @ngdoc directive
* @name ng.directive:ngPluralize
* @restrict EA
*
* @description
* # Overview
* `ngPluralize` is a directive that displays messages according to en-US localization rules.
* These rules are bundled with angular.js and the rules can be overridden
* (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
* by specifying the mappings between
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
* plural categories} and the strings to be displayed.
*
* # Plural categories and explicit number rules
* There are two
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
* plural categories} in Angular's default en-US locale: "one" and "other".
*
* While a pural category may match many numbers (for example, in en-US locale, "other" can match
* any number that is not 1), an explicit number rule can only match one number. For example, the
* explicit number rule for "3" matches the number 3. You will see the use of plural categories
* and explicit number rules throughout later parts of this documentation.
*
* # Configuring ngPluralize
* You configure ngPluralize by providing 2 attributes: `count` and `when`.
* You can also provide an optional attribute, `offset`.
*
* The value of the `count` attribute can be either a string or an {@link guide/expression
* Angular expression}; these are evaluated on the current scope for its bound value.
*
* The `when` attribute specifies the mappings between plural categories and the actual
* string to be displayed. The value of the attribute should be a JSON object so that Angular
* can interpret it correctly.
*
* The following example shows how to configure ngPluralize:
*
* <pre>
* <ng-pluralize count="personCount"
when="{'0': 'Nobody is viewing.',
* 'one': '1 person is viewing.',
* 'other': '{} people are viewing.'}">
* </ng-pluralize>
*</pre>
*
* In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
* specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
* would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
* other numbers, for example 12, so that instead of showing "12 people are viewing", you can
* show "a dozen people are viewing".
*
* You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
* into pluralized strings. In the previous example, Angular will replace `{}` with
* <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
* for <span ng-non-bindable>{{numberExpression}}</span>.
*
* # Configuring ngPluralize with offset
* The `offset` attribute allows further customization of pluralized text, which can result in
* a better user experience. For example, instead of the message "4 people are viewing this document",
* you might display "John, Kate and 2 others are viewing this document".
* The offset attribute allows you to offset a number by any desired value.
* Let's take a look at an example:
*
* <pre>
* <ng-pluralize count="personCount" offset=2
* when="{'0': 'Nobody is viewing.',
* '1': '{{person1}} is viewing.',
* '2': '{{person1}} and {{person2}} are viewing.',
* 'one': '{{person1}}, {{person2}} and one other person are viewing.',
* 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
* </ng-pluralize>
* </pre>
*
* Notice that we are still using two plural categories(one, other), but we added
* three explicit number rules 0, 1 and 2.
* When one person, perhaps John, views the document, "John is viewing" will be shown.
* When three people view the document, no explicit number rule is found, so
* an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
* In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
* is shown.
*
* Note that when you specify offsets, you must provide explicit number rules for
* numbers from 0 up to and including the offset. If you use an offset of 3, for example,
* you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
* plural categories "one" and "other".
*
* @param {string|expression} count The variable to be bounded to.
* @param {string} when The mapping between plural category to its correspoding strings.
* @param {number=} offset Offset to deduct from the total number.
*
* @example

* @ngdoc directive

*
* @description
* The `ngRepeat` directive instantiates a template once per item from a collection. Each template
* instance gets its own scope, where the given loop variable is set to the current collection item,
* and `$index` is set to the item index or key.
*
* Special properties are exposed on the local scope of each template instance, including:
*
* * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
* * `$first` – `{boolean}` – true if the repeated element is first in the iterator.
* * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.
* * `$last` – `{boolean}` – true if the repeated element is last in the iterator.
*
*
* @element ANY
* @scope
* @priority 1000
* @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. Two
* formats are currently supported:
*
* * `variable in expression` – where variable is the user defined loop variable and `expression`
* is a scope expression giving the collection to enumerate.
*
* For example: `track in cd.tracks`.
*
* * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
* and `expression` is the scope expression giving the collection to enumerate.
*
* For example: `(name, age) in {'adam':10, 'amalie':12}`.
*
* @example
* This example initializes the scope to a list of names and
* then uses `ngRepeat` to display every person:
<doc:example>
<doc:source>
<div ng-init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">

* @ngdoc directive
* @name ng.directive:select
* @restrict E
*
* @description
* HTML `SELECT` element with angular data-binding.
*
* # `ngOptions`
*
* Optionally `ngOptions` attribute can be used to dynamically generate a list of `<option>`
* elements for a `<select>` element using an array or an object obtained by evaluating the
* `ngOptions` expression.
*˝˝
* When an item in the select menu is select, the value of array element or object property
* represented by the selected option will be bound to the model identified by the `ngModel`
* directive of the parent select element.
*
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
* be nested into the `<select>` element. This element will then represent `null` or "not selected"
* option. See example below for demonstration.
*
* Note: `ngOptions` provides iterator facility for `<option>` element which should be used instead
* of {@link ng.directive:ngRepeat ngRepeat} when you want the
* `select` model to be bound to a non-string value. This is because an option element can currently
* be bound to string values only.
*
* @param {string} name assignable expression to data-bind to.
* @param {string=} required The control is considered valid only if value is entered.
* @param {comprehension_expression=} ngOptions in one of the following forms:
*
* * for array data sources:
* * `label` **`for`** `value` **`in`** `array`
* * `select` **`as`** `label` **`for`** `value` **`in`** `array`
* * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
* * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array`
* * for object data sources:
* * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
* * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
* * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
* * `select` **`as`** `label` **`group by`** `group`
* **`for` `(`**`key`**`,`** `value`**`) in`** `object`
*
* Where:
*
* * `array` / `object`: an expression which evaluates to an array / object to iterate over.
* * `value`: local variable which will refer to each item in the `array` or each property value
* of `object` during iteration.
* * `key`: local variable which will refer to a property name in `object` during iteration.
* * `label`: The result of this expression will be the label for `<option>` element. The
* `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
* * `select`: The result of this expression will be bound to the model of the parent `<select>`
* element. If not specified, `select` expression will default to `value`.
* * `group`: The result of this expression will be used to group options using the `<optgroup>`
* DOM element.

/**
* @ngdoc function
* @name angular.element
* @function
*
* @description
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
* `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
* jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
* implementation (commonly referred to as jqLite).
*
* Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
* event fired.
*
* jqLite is a tiny, API-compatible subset of jQuery that allows
* Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
* within a very small footprint, so only a subset of the jQuery API - methods, arguments and
* invocation styles - are supported.
*
* Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
* raw DOM references.
*
* ## Angular's jQuery lite provides the following methods:
*
* - [addClass()](http://api.jquery.com/addClass/)
* - [after()](http://api.jquery.com/after/)
* - [append()](http://api.jquery.com/append/)
* - [attr()](http://api.jquery.com/attr/)
* - [bind()](http://api.jquery.com/bind/)
* - [children()](http://api.jquery.com/children/)
* - [clone()](http://api.jquery.com/clone/)
* - [contents()](http://api.jquery.com/contents/)
* - [css()](http://api.jquery.com/css/)
* - [data()](http://api.jquery.com/data/)
* - [eq()](http://api.jquery.com/eq/)
* - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name.
* - [hasClass()](http://api.jquery.com/hasClass/)
* - [html()](http://api.jquery.com/html/)
* - [next()](http://api.jquery.com/next/)
* - [parent()](http://api.jquery.com/parent/)
* - [prepend()](http://api.jquery.com/prepend/)
* - [prop()](http://api.jquery.com/prop/)
* - [ready()](http://api.jquery.com/ready/)
* - [remove()](http://api.jquery.com/remove/)
* - [removeAttr()](http://api.jquery.com/removeAttr/)
* - [removeClass()](http://api.jquery.com/removeClass/)
* - [removeData()](http://api.jquery.com/removeData/)
* - [replaceWith()](http://api.jquery.com/replaceWith/)
* - [text()](http://api.jquery.com/text/)
* - [toggleClass()](http://api.jquery.com/toggleClass/)
* - [unbind()](http://api.jquery.com/unbind/)
* - [val()](http://api.jquery.com/val/)
* - [wrap()](http://api.jquery.com/wrap/)
*
* ## In addtion to the above, Angular privides an additional method to both jQuery and jQuery lite:
*
* - `controller(name)` - retrieves the controller of the current element or its parent. By default
* retrieves controller associated with the `ngController` directive. If `name` is provided as
* camelCase directive name, then the controller for this directive will be retrieved (e.g.
* `'ngModel'`).
* - `injector()` - retrieves the injector of the current element or its parent.
* - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
* element or its parent.
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
* parent element is reached.
*
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
* @returns {Object} jQuery object.

* @description
*
* `$injector` is used to retrieve object instances as defined by

* and load modules.
*
* The following always holds true:
*
* <pre>

* # Injection Function Annotation
*
* JavaScript does not have annotations, and annotations are needed for dependency injection. The
* following ways are all valid way of annotating function with injection arguments and are equivalent.
*
* <pre>
* // inferred (only works if code not minified/obfuscated)
* $inject.invoke(function(serviceA){});
*
* // annotated
* function explicit(serviceA) {};
* explicit.$inject = ['serviceA'];
* $inject.invoke(explicit);
*
* // inline
* $inject.invoke(['serviceA', function(serviceA){}]);
* </pre>
*
* ## Inference
*
* In JavaScript calling `toString()` on a function returns the function definition. The definition can then be
* parsed and the function arguments can be extracted. *NOTE:* This does not work with minification, and obfuscation
* tools since these tools change the argument names.
*
* ## `$inject` Annotation
* By adding a `$inject` property onto a function the injection parameters can be specified.
*
* ## Inline
* As an array of injection names, where the last item in the array is the function to call.

/**
* @ngdoc method
* @name AUTO.$injector#annotate
* @methodOf AUTO.$injector
*
* @description
* Returns an array of service names which the function is requesting for injection. This API is used by the injector
* to determine which services need to be injected into the function when the function is invoked. There are three
* ways in which the function can be annotated with the needed dependencies.
*
* # Argument names
*
* The simplest form is to extract the dependencies from the arguments of the function. This is done by converting
* the function into a string using `toString()` method and extracting the argument names.
* <pre>
* // Given
* function MyController($scope, $route) {
* // ...
* }
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* </pre>
*
* This method does not work with code minfication / obfuscation. For this reason the following annotation strategies
* are supported.
*
* # The `$injector` property
*
* If a function has an `$inject` property and its value is an array of strings, then the strings represent names of
* services to be injected into the function.
* <pre>
* // Given
* var MyController = function(obfuscatedScope, obfuscatedRoute) {
* // ...
* }
* // Define function dependencies
* MyController.$inject = ['$scope', '$route'];
*
* // Then
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
* </pre>
*
* # The array notation
*
* It is often desirable to inline Injected functions and that's when setting the `$inject` property is very
* inconvenient. In these situations using the array notation to specify the dependencies in a way that survives
* minification is a better choice:
*
* <pre>
* // We wish to write this (not minification / obfuscation safe)
* injector.invoke(function($compile, $rootScope) {
* // ...
* });
*
* // We are forced to write break inlining
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
* // ...
* };
* tmpFn.$inject = ['$compile', '$rootScope'];
* injector.invoke(tempFn);
*
* // To better support inline function the inline annotation is supported
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
* // ...
* }]);
*
* // Therefore
* expect(injector.annotate(
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
* ).toEqual(['$compile', '$rootScope']);
* </pre>
*
* @param {function|Array.<string|Function>} fn Function for which dependent service names need to be retrieved as described
* above.
*
* @returns {Array.<string>} The names of the services which the function requires.

*
* The template function can then be used once to produce the view or as it is the case with

*
* @param {string|DOMElement} element Element or HTML string to compile into a template function.
* @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
* @param {number} maxPriority only apply directives lower then given priority (Only effects the
* root element(s), not their children)
* @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
* (a DOM element/tree) to a scope. Where:
*
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
* `template` and call the `cloneAttachFn` function allowing the caller to attach the
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
* called as: <br> `cloneAttachFn(clonedElement, scope)` where:
*
* * `clonedElement` - is a clone of the original `element` passed into the compiler.
* * `scope` - is the current scope with which the linking function is working with.
*
* Calling the linking function returns the element of the template. It is either the original element
* passed in, or the clone of the element if the `cloneAttachFn` is provided.
*
* After linking the view is not updated until after a call to $digest which typically is done by
* Angular automatically.
*
* If you need access to the bound view, there are two ways to do it:
*
* - If you are not asking the linking function to clone the template, create the DOM element(s)
* before you send them to the compiler and keep this reference around.
* <pre>
* var element = $compile('<p>{{total}}</p>')(scope);
* </pre>
*
* - if on the other hand, you need the element to be cloned, the view reference from the original
* example would not point to the clone, but rather to the original template that was cloned. In
* this case, you can access the clone via the cloneAttachFn:
* <pre>
* var templateHTML = angular.element('<p>{{total}}</p>'),
* scope = ....;
*
* var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
* //attach the clone to DOM document at the right place
* });
*
* //now we have reference to the cloned DOM via `clone`
* </pre>
*
*
* For information on how the compiler works, see the
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

* @ngdoc service

*
* @description
* A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
*
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
* interface for interacting with an object that represents the result of an action that is
* performed asynchronously, and may or may not be finished at any given point in time.
*
* From the perspective of dealing with error handling, deferred and promise apis are to
* asynchronous programing what `try`, `catch` and `throw` keywords are to synchronous programing.
*
* <pre>
* // for the purpose of this example let's assume that variables `$q` and `scope` are
* // available in the current lexical scope (they could have been injected or passed in).
*
* function asyncGreet(name) {
* var deferred = $q.defer();
*
* setTimeout(function() {
* // since this fn executes async in a future turn of the event loop, we need to wrap
* // our code into an $apply call so that the model changes are properly observed.
* scope.$apply(function() {
* if (okToGreet(name)) {
* deferred.resolve('Hello, ' + name + '!');
* } else {
* deferred.reject('Greeting ' + name + ' is not allowed.');
* }
* });
* }, 1000);
*
* return deferred.promise;
* }
*
* var promise = asyncGreet('Robin Hood');
* promise.then(function(greeting) {
* alert('Success: ' + greeting);
* }, function(reason) {
* alert('Failed: ' + reason);
* );
* </pre>
*
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff
* comes in the way of
* [guarantees that promise and deferred apis make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md).
*
* Additionally the promise api allows for composition that is very hard to do with the
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
* section on serial or parallel joining of promises.
*
*
* # The Deferred API
*
* A new instance of deferred is constructed by calling `$q.defer()`.
*
* The purpose of the deferred object is to expose the associated Promise instance as well as apis
* that can be used for signaling the successful or unsuccessful completion of the task.
*
* **Methods**
*
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
* constructed via `$q.reject`, the promise will be rejected instead.
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
* resolving it with a rejection constructed via `$q.reject`.
*
* **Properties**
*
* - promise – `{Promise}` – promise object associated with this deferred.
*
*
* # The Promise API
*
* A new promise instance is created when a deferred instance is created and can be retrieved by
* calling `deferred.promise`.
*
* The purpose of the promise object is to allow for interested parties to get access to the result
* of the deferred task when it completes.
*
* **Methods**
*
* - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved
* or rejected calls one of the success or error callbacks asynchronously as soon as the result
* is available. The callbacks are called with a single argument the result or rejection reason.
*
* This method *returns a new promise* which is resolved or rejected via the return value of the
* `successCallback` or `errorCallback`.
*
*
* # Chaining promises
*
* Because calling `then` api of a promise returns a new derived promise, it is easily possible
* to create a chain of promises:
*
* <pre>
* promiseB = promiseA.then(function(result) {
* return result + 1;
* });
*
* // promiseB will be resolved immediately after promiseA is resolved and it's value will be
* // the result of promiseA incremented by 1
* </pre>
*
* It is possible to create chains of any length and since a promise can be resolved with another
* promise (which will defer its resolution further), it is possible to pause/defer resolution of
* the promises at any point in the chain. This makes it possible to implement powerful apis like
* $http's response interceptors.
*
*
* # Differences between Kris Kowal's Q and $q
*
* There are three main differences:
*
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
* mechanism in angular, which means faster propagation of resolution or rejection into your
* models and avoiding unnecessary browser repaints, which would result in flickering UI.
* - $q promises are recognized by the templating engine in angular, which means that in templates
* you can treat promises attached to a scope as if they were the resulting values.
* - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains
* all the important functionality needed for common async tasks.

* Is used for deep-linking URLs to controllers and views (HTML partials).
* It watches `$location.url()` and tries to map the path to an existing route definition.
*
* You can define routes through {@link ng.$routeProvider $routeProvider}'s API.
*
* The `$route` service is typically used in conjunction with {@link ng.directive:ngView ngView}
* directive and the {@link ng.$routeParams $routeParams} service.
*
* @example
This example shows how changing the URL hash causes the `$route` to match a route against the
URL, and the `ngView` pulls in the partial.
Note that this example is using {@link ng.directive:script inlined templates}
to get it working on jsfiddle as well.

* DESIGN NOTES
*
* The design decisions behind the scope ware heavily favored for speed and memory consumption.
*
* The typical use of scope is to watch the expressions, which most of the time return the same
* value as last time so we optimize the operation.
*
* Closures construction is expensive from speed as well as memory:
* - no closures, instead ups prototypical inheritance for API
* - Internal state needs to be stored on scope directly, which means that private state is
* exposed as $$____ properties
*
* Loop operations are optimized by using while(count--) { ... }
* - this means that in order to keep the same order of execution as addition we have to add
* items to the array at the begging (shift) instead of at the end (push)
*
* Child scopes are created and removed often
* - Using array would be slow since inserts in meddle are expensive so we use linked list
*
* There are few watches then a lot of observers. This is why you don't want the observer to be
* implemented in the same way as watch. Watch requires return of initialization function which
* are expensive to construct.

* @ngdoc function
* @name ng.$rootScope.Scope#$watch
* @methodOf ng.$rootScope.Scope
* @function
*
* @description
* Registers a `listener` callback to be executed whenever the `watchExpression` changes.
*
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest $digest()} and
* should return the value which will be watched. (Since {@link ng.$rootScope.Scope#$digest $digest()}
* reruns when it detects changes the `watchExpression` can execute multiple times per
* {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
* - The `listener` is called only when the value from the current `watchExpression` and the
* previous call to `watchExpression' are not equal (with the exception of the initial run
* see below). The inequality is determined according to
* {@link angular.equals} function. To save the value of the object for later comparison
* {@link angular.copy} function is used. It also means that watching complex options will
* have adverse memory and performance implications.
* - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
* is achieved by rerunning the watchers until no changes are detected. The rerun iteration
* limit is 100 to prevent infinity loop deadlock.
*
*
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
* you can register an `watchExpression` function with no `listener`. (Since `watchExpression`,
* can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a change is
* detected, be prepared for multiple calls to your listener.)
*
* After a watcher is registered with the scope, the `listener` fn is called asynchronously
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
* watcher. In rare cases, this is undesirable because the listener is called when the result
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
* listener was called due to initialization.
*
*
* # Example
* <pre>
// let's assume that scope was dependency injected as the $rootScope
var scope = $rootScope;
scope.name = 'misko';
scope.counter = 0;
expect(scope.counter).toEqual(0);
scope.$watch('name', function(newValue, oldValue) { counter = counter + 1; });

scope.$digest();

* </pre>
*

*
* @param {(function()|string)} watchExpression Expression that is evaluated on each

*
* - `string`: Evaluated as {@link guide/expression expression}
* - `function(scope)`: called with current `scope` as a parameter.
* @param {(function()|string)=} listener Callback called whenever the return value of
* the `watchExpression` changes.
*
* - `string`: Evaluated as {@link guide/expression expression}
* - `function(newValue, oldValue, scope)`: called with current and previous values as parameters.

* @ngdoc function
* @name ng.$http
* @requires $httpBacked
* @requires $browser
* @requires $cacheFactory
* @requires $rootScope
* @requires $q
* @requires $injector
*
* @description
* The `$http` service is a core Angular service that facilitates communication with the remote
* HTTP servers via browser's {@link https://developer.mozilla.org/en/xmlhttprequest
* XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}.
*
* For unit testing applications that use `$http` service, see
* {@link ngMock.$httpBackend $httpBackend mock}.
*
* For a higher level of abstraction, please check out the {@link ngResource.$resource
* $resource} service.
*
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
* the $q service. While for simple usage patters this doesn't matter much, for advanced usage,
* it is important to familiarize yourself with these apis and guarantees they provide.
*
*
* # General usage
* The `$http` service is a function which takes a single argument — a configuration object —
* that is used to generate an http request and returns a {@link ng.$q promise}
* with two $http specific methods: `success` and `error`.
*
* <pre>
* $http({method: 'GET', url: '/someUrl'}).
* success(function(data, status, headers, config) {
* // this callback will be called asynchronously
* // when the response is available
* }).
* error(function(data, status, headers, config) {
* // called asynchronously if an error occurs
* // or server returns response with status
* // code outside of the <200, 400) range
* });
* </pre>
*
* Since the returned value of calling the $http function is a Promise object, you can also use
* the `then` method to register callbacks, and these callbacks will receive a single argument –
* an object representing the response. See the api signature and type info below for more
* details.
*
*
* # Shortcut methods
*
* Since all invocation of the $http service require definition of the http method and url and
* POST and PUT requests require response body/data to be provided as well, shortcut methods
* were created to simplify using the api:
*
* <pre>
* $http.get('/someUrl').success(successCallback);
* $http.post('/someUrl', data).success(successCallback);
* </pre>
*
* Complete list of shortcut methods:
*
* - {@link ng.$http#get $http.get}
* - {@link ng.$http#head $http.head}
* - {@link ng.$http#post $http.post}
* - {@link ng.$http#put $http.put}
* - {@link ng.$http#delete $http.delete}
* - {@link ng.$http#jsonp $http.jsonp}
*
*
* # Setting HTTP Headers
*
* The $http service will automatically add certain http headers to all requests. These defaults
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
* object, which currently contains this default configuration:
*
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
* - `Accept: application/json, text/plain, * / *`
* - `X-Requested-With: XMLHttpRequest`
* - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests)
* - `Content-Type: application/json`
* - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests)
* - `Content-Type: application/json`
*
* To add or overwrite these defaults, simply add or remove a property from this configuration
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
* with name equal to the lower-cased http method name, e.g.
* `$httpProvider.defaults.headers.get['My-Header']='value'`.
*
* Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar
* fassion as described above.
*
*
* # Transforming Requests and Responses
*
* Both requests and responses can be transformed using transform functions. By default, Angular
* applies these transformations:
*
* Request transformations:
*
* - if the `data` property of the request config object contains an object, serialize it into
* JSON format.
*
* Response transformations:
*
* - if XSRF prefix is detected, strip it (see Security Considerations section below)
* - if json response is detected, deserialize it using a JSON parser
*
* To override these transformation locally, specify transform functions as `transformRequest`
* and/or `transformResponse` properties of the config object. To globally override the default
* transforms, override the `$httpProvider.defaults.transformRequest` and
* `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`.
*
*
* # Caching
*
* To enable caching set the configuration property `cache` to `true`. When the cache is
* enabled, `$http` stores the response from the server in local cache. Next time the
* response is served from the cache without sending a request to the server.
*
* Note that even if the response is served from cache, delivery of the data is asynchronous in
* the same way that real requests are.
*
* If there are multiple GET requests for the same url that should be cached using the same
* cache, but the cache is not populated yet, only one request to the server will be made and
* the remaining requests will be fulfilled using the response for the first request.
*
*
* # Response interceptors
*
* Before you start creating interceptors, be sure to understand the
* {@link ng.$q $q and deferred/promise APIs}.
*
* For purposes of global error handling, authentication or any kind of synchronous or
* asynchronous preprocessing of received responses, it is desirable to be able to intercept
* responses for http requests before they are handed over to the application code that
* initiated these requests. The response interceptors leverage the {@link ng.$q
* promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
*
* The interceptors are service factories that are registered with the $httpProvider by
* adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
* injected with dependencies (if specified) and returns the interceptor — a function that
* takes a {@link ng.$q promise} and returns the original or a new promise.
*
* <pre>
* // register the interceptor as a service
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
* return function(promise) {
* return promise.then(function(response) {
* // do something on success
* }, function(response) {
* // do something on error
* if (canRecover(response)) {
* return responseOrNewPromise
* }
* return $q.reject(response);
* });
* }
* });
*
* $httpProvider.responseInterceptors.push('myHttpInterceptor');
*
*
* // register the interceptor via an anonymous factory
* $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
* return function(promise) {
* // same as above
* }
* });
* </pre>
*
*
* # Security Considerations
*
* When designing web applications, consider security threats from:
*
* - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability}
* - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
*
* Both server and the client must cooperate in order to eliminate these threats. Angular comes
* pre-configured with strategies that address these issues, but for this to work backend server
* cooperation is required.
*
* ## JSON Vulnerability Protection
*
* A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
* JSON Vulnerability} allows third party web-site to turn your JSON resource URL into
* {@link http://en.wikipedia.org/wiki/JSON#JSONP JSONP} request under some conditions. To
* counter this your server can prefix all JSON requests with following string `")]}',\n"`.
* Angular will automatically strip the prefix before processing it as JSON.
*
* For example if your server needs to return:
* <pre>
* ['one','two']
* </pre>
*
* which is vulnerable to attack, your server can return:
* <pre>
* )]}',
* ['one','two']
* </pre>
*
* Angular will strip the prefix, before processing the JSON.
*
*
* ## Cross Site Request Forgery (XSRF) Protection
*
* {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
* an unauthorized site can gain your user's private data. Angular provides following mechanism
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
* called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
* runs on your domain could read the cookie, your server can be assured that the XHR came from
* JavaScript running on your domain.
*
* To take advantage of this, your server needs to set a token in a JavaScript readable session
* cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET requests the
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
* that only JavaScript running on your domain could have read the token. The token must be
* unique for each user and must be verifiable by the server (to prevent the JavaScript making
* up its own tokens). We recommend that the token is a digest of your site's authentication
* cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}.
*
*
* @param {object} config Object describing the request to be made and how it should be
* processed. The object has following properties:
*
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned to
* `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified.
* - **data** – `{string|Object}` – Data to be sent as the request message data.
* - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server.
* - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* request body and headers and returns its transformed (typically serialized) version.
* - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
* transform function or an array of such functions. The transform function takes the http
* response body and headers and returns its transformed (typically deserialized) version.
* - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
* GET request, otherwise if a cache instance built with
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
* caching.
* - **timeout** – `{number}` – timeout in milliseconds.
* - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
* XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
* requests with credentials} for more information.
*
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
* standard `then` method and two http specific methods: `success` and `error`. The `then`
* method takes two arguments a success and an error callback which will be called with a
* response object. The `success` and `error` methods take a single argument - a function that
* will be called when the request succeeds or fails respectively. The arguments passed into
* these functions are destructured representation of the response object passed into the
* `then` method. The response object has these properties:
*
* - **data** – `{string|Object}` – The response body transformed with the transform functions.
* - **status** – `{number}` – HTTP status code of the response.
* - **headers** – `{function([headerName])}` – Header getter function.
* - **config** – `{Object}` – The configuration object that was used to generate the request.
*
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending
* requests. This is primarily meant to be used for debugging purposes.

* @ngdoc filter
* @name ng.filter:filter
* @function
*
* @description
* Selects a subset of items from `array` and returns it as a new array.
*
* Note: This function is used to augment the `Array` type in Angular expressions. See
* {@link ng.$filter} for more information about Angular arrays.
*
* @param {Array} array The source array.
* @param {string|Object|function()} expression The predicate to be used for selecting items from
* `array`.
*
* Can be one of:
*
* - `string`: Predicate that results in a substring match using the value of `expression`
* string. All strings or objects with string properties in `array` that contain this string
* will be returned. The predicate can be negated by prefixing the string with `!`.
*
* - `Object`: A pattern object can be used to filter specific properties on objects contained
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
* which have property `name` containing "M" and property `phone` containing "1". A special
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any
* property of the object. That's equivalent to the simple substring match with a `string`
* as described above.
*
* - `function`: A predicate function can be used to write arbitrary filters. The function is
* called for each element of `array`. The final result is an array of those elements that
* the predicate returned true for.

/**
* @ngdoc filter
* @name ng.filter:date
* @function
*
* @description
* Formats `date` to a string based on the requested `format`.
*
* `format` string can be composed of the following elements:
*
* * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
* * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
* * `'MMMM'`: Month in year (January-December)
* * `'MMM'`: Month in year (Jan-Dec)
* * `'MM'`: Month in year, padded (01-12)
* * `'M'`: Month in year (1-12)
* * `'dd'`: Day in month, padded (01-31)
* * `'d'`: Day in month (1-31)
* * `'EEEE'`: Day in Week,(Sunday-Saturday)
* * `'EEE'`: Day in Week, (Sun-Sat)
* * `'HH'`: Hour in day, padded (00-23)
* * `'H'`: Hour in day (0-23)
* * `'hh'`: Hour in am/pm, padded (01-12)
* * `'h'`: Hour in am/pm, (1-12)
* * `'mm'`: Minute in hour, padded (00-59)
* * `'m'`: Minute in hour (0-59)
* * `'ss'`: Second in minute, padded (00-59)
* * `'s'`: Second in minute (0-59)
* * `'a'`: am/pm marker
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-1200)
*
* `format` string can also be one of the following predefined
* {@link guide/i18n localizable formats}:
*
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
* (e.g. Sep 3, 2010 12:05:08 pm)
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 pm)
* * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US locale
* (e.g. Friday, September 3, 2010)
* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
*
* `format` string can contain literal values. These need to be quoted with single quotes (e.g.
* `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
* (e.g. `"h o''clock"`).
*
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and it's
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ).
* @param {string=} format Formatting rules (see Description). If not specified,
* `mediumDate` is used.
* @returns {string} Formatted string or the input if input is not recognized as date/millis.

/**
* @ngdoc directive
* @name ng.directive:form
* @restrict E
*
* @description
* Directive that instantiates
* {@link ng.directive:form.FormController FormController}.
*
* If `name` attribute is specified, the form controller is published onto the current scope under
* this name.
*
* # Alias: {@link ng.directive:ngForm `ngForm`}
*
* In angular forms can be nested. This means that the outer form is valid when all of the child
* forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this
* reason angular provides {@link ng.directive:ngForm `ngForm`} alias
* which behaves identical to `<form>` but allows form nesting.
*
*
* # CSS classes
* - `ng-valid` Is set if the form is valid.
* - `ng-invalid` Is set if the form is invalid.
* - `ng-pristine` Is set if the form is pristine.
* - `ng-dirty` Is set if the form is dirty.
*
*
* # Submitting a form and preventing default action
*
* Since the role of forms in client-side Angular applications is different than in classical
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full
* page reload that sends the data to the server. Instead some javascript logic should be triggered
* to handle the form submission in application specific way.
*
* For this reason, Angular prevents the default action (form submission to the server) unless the
* `<form>` element has an `action` attribute specified.
*
* You can use one of the following two ways to specify what javascript method should be called when
* a form is submitted:
*
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
* - {@link ng.directive:ngClick ngClick} directive on the first
* button or input field of type submit (input[type=submit])
*
* To prevent double execution of the handler, use only one of ngSubmit or ngClick directives. This
* is because of the following form submission rules coming from the html spec:
*
* - If a form has only one input field then hitting enter in this field triggers form submit
* (`ngSubmit`)
* - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter
* doesn't trigger submit
* - if a form has one or more input fields and one or more buttons or input[type=submit] then
* hitting enter in any of the input fields will trigger the click handler on the *first* button or
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
*
* @param {string=} name Name of the form. If specified, the form controller will be published into
* related scope, under this name.

* `NgModelController` provides API for the `ng-model` directive. The controller contains
* services for data-binding, validation, CSS update, value formatting and parsing. It
* specifically does not contain any logic which deals with DOM rendering or listening to
* DOM events. The `NgModelController` is meant to be extended by other directives where, the
* directive provides DOM manipulation and the `NgModelController` provides the data-binding.
*
* This example shows how to use `NgModelController` with a custom control to achieve
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
* collaborate together to achieve the desired result.
*
* <example module="customControl">
<file name="style.css">
[contenteditable] {
border: 1px solid black;
background-color: white;
min-height: 20px;
}
.ng-invalid {
border: 1px solid red;
}
</file>
<file name="script.js">
angular.module('customControl', []).

return {
restrict: 'A', // only activate on element attribute
require: '?ngModel', // get a hold of NgModelController

if(!ngModel) return; // do nothing if no ng-model
// Specify how UI should be updated

};
// Listen for change events to enable binding
element.bind('blur keyup change', function() {

read(); // initialize
// Write data to the model
function read() {
ngModel.$setViewValue(element.html());

*
* `ngModel` is responsible for:
*

* require,
* - providing validation behavior (i.e. required, number, email, url),
* - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
* - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
* - register the control with parent {@link ng.directive:form form}.
*
* For basic examples, how to use `ngModel`, see:
*
* - {@link ng.directive:input input}
* - {@link ng.directive:input.text text}
* - {@link ng.directive:input.checkbox checkbox}
* - {@link ng.directive:input.radio radio}

* @description
* The `ngCloak` directive is used to prevent the Angular html template from being briefly
* displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
* directive to avoid the undesirable flicker effect caused by the html template display.
*
* The directive can be applied to the `<body>` element, but typically a fine-grained application is
* prefered in order to benefit from progressive rendering of the browser view.
*
* `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and
* `angular.min.js` files. Following is the css rule:
*
* <pre>
* [ng\:cloak], [ng-cloak], .ng-cloak {
* display: none;
* }
* </pre>
*
* When this css rule is loaded by the browser, all html elements (including their children) that
* are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive
* during the compilation of the template it deletes the `ngCloak` element attribute, which
* makes the compiled element visible.
*
* For the best result, `angular.js` script must be loaded in the head section of the html file;
* alternatively, the css rule (above) must be included in the external stylesheet of the
* application.
*
* Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
* cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
* class `ngCloak` in addition to `ngCloak` directive as shown in the example below.
*

*
* @example
<doc:example>

/**

*
* @description
* The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular
* supports the principles behind the Model-View-Controller design pattern.
*
* MVC components in angular:
*
* * Model — The Model is data in scope properties; scopes are attached to the DOM.
* * View — The template (HTML with data bindings) is rendered into the View.
* * Controller — The `ngController` directive specifies a Controller class; the class has
* methods that typically express the business logic behind the application.
*
* Note that an alternative way to define controllers is via the `{@link ng.$route}`
* service.
*
* @element ANY
* @scope
* @param {expression} ngController Name of a globally accessible constructor function or an
* {@link guide/expression expression} that on the current scope evaluates to a
* constructor function.
*
* @example
* Here is a simple form for editing user contact information. Adding, removing, clearing, and
* greeting are methods declared on the controller (see source tab). These methods can
* easily be called from the angular markup. Notice that the scope becomes the `this` for the
* controller's instance. This allows for easy access to the view data from the controller. Also
* notice that any changes to the data are automatically reflected in the View without the need
* for a manual update.

/**
* @ngdoc directive
* @name ng.directive:ngPluralize
* @restrict EA
*
* @description
* # Overview
* `ngPluralize` is a directive that displays messages according to en-US localization rules.
* These rules are bundled with angular.js and the rules can be overridden
* (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
* by specifying the mappings between
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
* plural categories} and the strings to be displayed.
*
* # Plural categories and explicit number rules
* There are two
* {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html
* plural categories} in Angular's default en-US locale: "one" and "other".
*
* While a pural category may match many numbers (for example, in en-US locale, "other" can match
* any number that is not 1), an explicit number rule can only match one number. For example, the
* explicit number rule for "3" matches the number 3. You will see the use of plural categories
* and explicit number rules throughout later parts of this documentation.
*
* # Configuring ngPluralize
* You configure ngPluralize by providing 2 attributes: `count` and `when`.
* You can also provide an optional attribute, `offset`.
*
* The value of the `count` attribute can be either a string or an {@link guide/expression
* Angular expression}; these are evaluated on the current scope for its bound value.
*
* The `when` attribute specifies the mappings between plural categories and the actual
* string to be displayed. The value of the attribute should be a JSON object so that Angular
* can interpret it correctly.
*
* The following example shows how to configure ngPluralize:
*
* <pre>
* <ng-pluralize count="personCount"
when="{'0': 'Nobody is viewing.',
* 'one': '1 person is viewing.',
* 'other': '{} people are viewing.'}">
* </ng-pluralize>
*</pre>
*
* In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
* specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
* would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
* other numbers, for example 12, so that instead of showing "12 people are viewing", you can
* show "a dozen people are viewing".
*
* You can use a set of closed braces(`{}`) as a placeholder for the number that you want substituted
* into pluralized strings. In the previous example, Angular will replace `{}` with
* <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
* for <span ng-non-bindable>{{numberExpression}}</span>.
*
* # Configuring ngPluralize with offset
* The `offset` attribute allows further customization of pluralized text, which can result in
* a better user experience. For example, instead of the message "4 people are viewing this document",
* you might display "John, Kate and 2 others are viewing this document".
* The offset attribute allows you to offset a number by any desired value.
* Let's take a look at an example:
*
* <pre>
* <ng-pluralize count="personCount" offset=2
* when="{'0': 'Nobody is viewing.',
* '1': '{{person1}} is viewing.',
* '2': '{{person1}} and {{person2}} are viewing.',
* 'one': '{{person1}}, {{person2}} and one other person are viewing.',
* 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
* </ng-pluralize>
* </pre>
*
* Notice that we are still using two plural categories(one, other), but we added
* three explicit number rules 0, 1 and 2.
* When one person, perhaps John, views the document, "John is viewing" will be shown.
* When three people view the document, no explicit number rule is found, so
* an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
* In this case, plural category 'one' is matched and "John, Marry and one other person are viewing"
* is shown.
*
* Note that when you specify offsets, you must provide explicit number rules for
* numbers from 0 up to and including the offset. If you use an offset of 3, for example,
* you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
* plural categories "one" and "other".
*
* @param {string|expression} count The variable to be bounded to.
* @param {string} when The mapping between plural category to its correspoding strings.
* @param {number=} offset Offset to deduct from the total number.
*

/**
* @ngdoc directive
* @name ng.directive:ngRepeat
*
* @description
* The `ngRepeat` directive instantiates a template once per item from a collection. Each template
* instance gets its own scope, where the given loop variable is set to the current collection item,
* and `$index` is set to the item index or key.
*
* Special properties are exposed on the local scope of each template instance, including:
*
* * `$index` – `{number}` – iterator offset of the repeated element (0..length-1)
* * `$first` – `{boolean}` – true if the repeated element is first in the iterator.
* * `$middle` – `{boolean}` – true if the repeated element is between the first and last in the iterator.
* * `$last` – `{boolean}` – true if the repeated element is last in the iterator.
*
*
* @element ANY
* @scope
* @priority 1000
* @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. Two
* formats are currently supported:
*
* * `variable in expression` – where variable is the user defined loop variable and `expression`
* is a scope expression giving the collection to enumerate.
*
* For example: `track in cd.tracks`.
*
* * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
* and `expression` is the scope expression giving the collection to enumerate.
*
* For example: `(name, age) in {'adam':10, 'amalie':12}`.
*
* @example
* This example initializes the scope to a list of names and
* then uses `ngRepeat` to display every person:
<doc:example>
<doc:source>
<div ng-init="friends = [{name:'John', age:25}, {name:'Mary', age:28}]">
I have {{friends.length}} friends. They are:
<ul>
<li ng-repeat="friend in friends">
[{{$index + 1}}] {{friend.name}} who is {{friend.age}} years old.
</li>
</ul>

* @ngdoc directive
* @name ng.directive:select
* @restrict E
*
* @description
* HTML `SELECT` element with angular data-binding.
*
* # `ngOptions`
*
* Optionally `ngOptions` attribute can be used to dynamically generate a list of `<option>`
* elements for a `<select>` element using an array or an object obtained by evaluating the
* `ngOptions` expression.
*˝˝
* When an item in the select menu is select, the value of array element or object property
* represented by the selected option will be bound to the model identified by the `ngModel`
* directive of the parent select element.
*
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
* be nested into the `<select>` element. This element will then represent `null` or "not selected"
* option. See example below for demonstration.
*
* Note: `ngOptions` provides iterator facility for `<option>` element which should be used instead
* of {@link ng.directive:ngRepeat ngRepeat} when you want the
* `select` model to be bound to a non-string value. This is because an option element can currently
* be bound to string values only.
*
* @param {string} name assignable expression to data-bind to.
* @param {string=} required The control is considered valid only if value is entered.
* @param {comprehension_expression=} ngOptions in one of the following forms:
*
* * for array data sources:
* * `label` **`for`** `value` **`in`** `array`
* * `select` **`as`** `label` **`for`** `value` **`in`** `array`
* * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
* * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array`
* * for object data sources:
* * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
* * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
* * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
* * `select` **`as`** `label` **`group by`** `group`
* **`for` `(`**`key`**`,`** `value`**`) in`** `object`
*
* Where:
*
* * `array` / `object`: an expression which evaluates to an array / object to iterate over.
* * `value`: local variable which will refer to each item in the `array` or each property value
* of `object` during iteration.
* * `key`: local variable which will refer to a property name in `object` during iteration.
* * `label`: The result of this expression will be the label for `<option>` element. The
* `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
* * `select`: The result of this expression will be bound to the model of the parent `<select>`
* element. If not specified, `select` expression will default to `value`.
* * `group`: The result of this expression will be used to group options using the `<optgroup>`
* DOM element.

* @ngdoc object
* @name ngMock.$httpBackend
* @description
* Fake HTTP backend implementation suitable for unit testing application that use the
* {@link ng.$http $http service}.
*
* *Note*: For fake http backend implementation suitable for end-to-end testing or backend-less
* development please see {@link ngMockE2E.$httpBackend e2e $httpBackend mock}.
*
* During unit testing, we want our unit tests to run quickly and have no external dependencies so
* we don’t want to send {@link https://developer.mozilla.org/en/xmlhttprequest XHR} or
* {@link http://en.wikipedia.org/wiki/JSONP JSONP} requests to a real server. All we really need is
* to verify whether a certain request has been sent or not, or alternatively just let the
* application make requests, respond with pre-trained responses and assert that the end result is
* what we expect it to be.
*
* This mock implementation can be used to respond with static or dynamic responses via the
* `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc).
*
* When an Angular application needs some data from a server, it calls the $http service, which
* sends the request to a real server using $httpBackend service. With dependency injection, it is
* easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify
* the requests and respond with some testing data without sending a request to real server.
*
* There are two ways to specify what test data should be returned as http responses by the mock
* backend when the code under test makes http requests:
*
* - `$httpBackend.expect` - specifies a request expectation
* - `$httpBackend.when` - specifies a backend definition
*
*
* # Request Expectations vs Backend Definitions
*
* Request expectations provide a way to make assertions about requests made by the application and
* to define responses for those requests. The test will fail if the expected requests are not made
* or they are made in the wrong order.
*
* Backend definitions allow you to define a fake backend for your application which doesn't assert
* if a particular request was made or not, it just returns a trained response if a request is made.
* The test will pass whether or not the request gets made during testing.
*
*
* <table class="table">
* <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>
* <tr>
* <th>Syntax</th>
* <td>.expect(...).respond(...)</td>
* <td>.when(...).respond(...)</td>
* </tr>
* <tr>
* <th>Typical usage</th>
* <td>strict unit tests</td>
* <td>loose (black-box) unit testing</td>
* </tr>
* <tr>
* <th>Fulfills multiple requests</th>
* <td>NO</td>
* <td>YES</td>
* </tr>
* <tr>
* <th>Order of requests matters</th>
* <td>YES</td>
* <td>NO</td>
* </tr>
* <tr>
* <th>Request required</th>
* <td>YES</td>
* <td>NO</td>
* </tr>
* <tr>
* <th>Response required</th>
* <td>optional (see below)</td>
* <td>YES</td>
* </tr>
* </table>
*
* In cases where both backend definitions and request expectations are specified during unit
* testing, the request expectations are evaluated first.
*
* If a request expectation has no response specified, the algorithm will search your backend
* definitions for an appropriate response.
*
* If a request didn't match any expectation or if the expectation doesn't have the response
* defined, the backend definitions are evaluated in sequential order to see if any of them match
* the request. The response from the first matched definition is returned.
*
*
* # Flushing HTTP requests
*
* The $httpBackend used in production, always responds to requests with responses asynchronously.
* If we preserved this behavior in unit testing, we'd have to create async unit tests, which are
* hard to write, follow and maintain. At the same time the testing mock, can't respond
* synchronously because that would change the execution of the code under test. For this reason the
* mock $httpBackend has a `flush()` method, which allows the test to explicitly flush pending
* requests and thus preserving the async api of the backend, while allowing the test to execute
* synchronously.
*
*

*
* *Note*: For fake http backend implementation suitable for unit testing please see
* {@link ngMock.$httpBackend unit-testing $httpBackend mock}.
*
* This implementation can be used to respond with static or dynamic responses via the `when` api
* and its shortcuts (`whenGET`, `whenPOST`, etc) and optionally pass through requests to the
* real $httpBackend for specific requests (e.g. to interact with certain remote apis or to fetch
* templates from a webserver).
*
* As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
* is being developed with the real backend api replaced with a mock, it is often desirable for
* certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
* templates or static files from the webserver). To configure the backend with this behavior
* use the `passThrough` request handler of `when` instead of `respond`.
*
* Additionally, we don't want to manually have to flush mocked out requests like we do during unit
* testing. For this reason the e2e $httpBackend automatically flushes mocked out requests
* automatically, closely simulating the behavior of the XMLHttpRequest object.
*
* To setup the application to run with this http backend, you have to create a module that depends
* on the `ngMockE2E` and your application modules and defines the fake backend:
*
* <pre>
* myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
* myAppDev.run(function($httpBackend) {
* phones = [{name: 'phone1'}, {name: 'phone2'}];
*
* // returns the current list of phones
* $httpBackend.whenGET('/phones').respond(phones);
*
* // adds a new phone to the phones array
* $httpBackend.whenPOST('/phones').respond(function(method, url, data) {
* phones.push(angular.fromJSON(data));
* });
* $httpBackend.whenGET(/^\/templates\//).passThrough();
* //...
* });
* </pre>
*
* Afterwards, bootstrap your app with this new module.
