treating that method as an event</li>
</ul>
For custom event subscriptions, pass the custom event name as the first argument and callback as the second. The `this` object in the callback will be `Y` unless an override is passed as the third argument.
Y.on('io:complete', function () {
Y.MyApp.updateStatus('Transaction complete');
});
To subscribe to DOM events, pass the name of a DOM event as the first argument
and a CSS selector string as the third argument after the callback function.
Alternately, the third argument can be a `Node`, `NodeList`, `HTMLElement`,
array, or simply omitted (the default is the `window` object).
Y.on('click', function (e) {
e.preventDefault();
// proceed with ajax form submission
var url = this.get('action');
...
}, '#my-form');
The `this` object in DOM event callbacks will be the `Node` targeted by the CSS
selector or other identifier.
`on()` subscribers for DOM events or custom events `publish`ed with a
`defaultFn` can prevent the default behavior with `e.preventDefault()` from the
event object passed as the first parameter to the subscription callback.
To subscribe to the execution of an object method, pass arguments corresponding to the call signature for
<a href="../classes/Do.html#methods_before">`Y.Do.before(...)`</a>.
NOTE: The formal parameter list below is for events, not for function
injection. See `Y.Do.before` for that signature.

@param {Function} fn The callback to execute in response to the event

/**
* `Transaction` creates a black box that is able to wrap any method such that
* certain invariants are maintained before and after the method is invoked
* (Even if an exception is thrown while invoking the wrapped method). Whoever
* instantiates a transaction can provide enforcers of the invariants at
* creation time. The `Transaction` class itself will supply one additional
* automatic invariant for you - the invariant that any transaction instance
* should not be run while it is already being run. You would typically create a
* single instance of a `Transaction` for reuse multiple times, that potentially
* is used to wrap several different methods. Wrappers are extremely simple -
* they only require implementing two methods.

* Use cases:
* - Preserving the input selection ranges before/after reconciliation.
* Restoring selection even in the event of an unexpected error.
* - Deactivating events while rearranging the DOM, preventing blurs/focuses,
* while guaranteeing that afterwards, the event system is reactivated.
* - Flushing a queue of collected DOM mutations to the main UI thread after a
* reconciliation takes place in a worker thread.
* - Invoking any collected `componentDidUpdate` callbacks after rendering new
* content.
* - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
* to preserve the `scrollTop` (an automatic scroll aware DOM).
* - (Future use case): Layout calculations before and after DOM upates.
*
* Transactional plugin API:
* - A module that has an `initialize` method that returns any precomputation.
* - and a `close` method that accepts the precomputation. `close` is invoked
* when the wrapped process is completed, or has failed.

* Select a set of or single entities by components or an entity's ID.

* Crafty uses syntax similar to jQuery by having a selector engine to select entities by their components.
*
* If there is more than one match, the return value is an Array-like object listing the ID numbers of each matching entity. If there is exactly one match, the entity itself is returned. If you're not sure how many matches to expect, check the number of matches via Crafty(...).length. Alternatively, use Crafty(...).each(...), which works in all cases.
*
* @example
* ~~~
* Crafty("MyComponent")
* Crafty("Hello 2D Component")
* Crafty("Hello, 2D, Component")
* ~~~
*
* The first selector will return all entities that have the component `MyComponent`. The second will return all entities that have `Hello` and `2D` and `Component` whereas the last will return all entities that have at least one of those components (or).
*
* ~~~
* Crafty("*")
* ~~~
* Passing `*` will select all entities.
*
* ~~~
* Crafty(1)
* ~~~
* Passing an integer will select the entity with that `ID`.

* is the object that will be inherited by entities.
*
* A couple of methods are treated specially. They are invoked in partiular contexts, and (in those contexts) cannot be overridden by other components.
*
* - `init` will be called when the component is added to an entity
* - `remove` will be called just before a component is removed, or before an entity is destroyed. It is passed a single boolean parameter that is `true` if the entity is being destroyed.
*
* In addition to these hardcoded special methods, there are some conventions for writing components.
*
* - Properties or methods that start with an underscore are considered private.
* - A method with the same name as the component is considered to be a constructor
* and is generally used when you need to pass configuration data to the component on a per entity basis.
*
* @example
* ~~~
* Crafty.c("Annoying", {
* _message: "HiHi",
* init: function() {
* this.bind("EnterFrame", function() { alert(this.message); });
* },
* annoying: function(message) { this.message = message; }
* });
*
* Crafty.e("Annoying").annoying("I'm an orange...");
* ~~~
*
*
* WARNING:
*
* in the example above the field _message is local to the entity. That is, if you create many entities with the Annoying component they can all have different values for _message. That is because it is a simple value, and simple values are copied by value. If however the field had been an object or array, the value would have been shared by all entities with the component because complex types are copied by reference in javascript. This is probably not what you want and the following example demonstrates how to work around it:
*
* ~~~
* Crafty.c("MyComponent", {
* _iAmShared: { a: 3, b: 4 },
* init: function() {
* this._iAmNotShared = { a: 3, b: 4 };

* @param tileh - Height of the tile; if provided, tile is interpreted as the width
* @param url - URL of the sprite image
* @param map - Object where the key is what becomes a new component and the value points to a position on the sprite map
* @param paddingX - Horizontal space in between tiles. Defaults to 0.
* @param paddingY - Vertical space in between tiles. Defaults to paddingX.
* Generates components based on positions in a sprite image to be applied to entities.
*
* Accepts a tile size, URL and map for the name of the sprite and its position.
*
* The position must be an array containing the position of the sprite where index `0`
* is the `x` position, `1` is the `y` position and optionally `2` is the width and `3`
* is the height. If the sprite map has padding, pass the values for the `x` padding
* or `y` padding. If they are the same, just add one value.
*
* If the sprite image has no consistent tile size, `1` or no argument need be
* passed for tile size.
*
* Entities that add the generated components are also given a component called `Sprite`.
*
* @example
* ~~~
* Crafty.sprite("imgs/spritemap6.png", {flower:[0,0,20,30]});
* var flower_entity = Crafty.e("2D, DOM, flower");
* ~~~
* The first line creates a component called `flower` associated with the sub-image of
* spritemap6.png with top-left corner (0,0), width 20 pixels, and height 30 pixels.
* The second line creates an entity with that image. (Note: `Crafty.e("flower, 2D, DOM")`
* would NOT work. When the `2D` component is assigned, it erases the width and height
* information. So you should list `2D` before `flower`.)
* ~~~
* Crafty.sprite(50, "imgs/spritemap6.png", {flower:[0,0], grass:[0,1,3,1]});
* ~~~
* In this case, the `flower` component is pixels 0 <= x < 50, 0 <= y < 50, and the
* `grass` component is pixels 0 <= x < 150, 50 <= y < 100. (The `3` means grass has a
* width of 3 tiles, i.e. 150 pixels.)
* ~~~
* Crafty.sprite(50, 100, "imgs/spritemap6.png", {flower:[0,0], grass:[0,1]}, 10);
* ~~~
* In this case, each tile is 50x100, and there is a spacing of 10 pixels between
* consecutive tiles. So `flower` is pixels 0 <= x < 50, 0 <= y < 100, and `grass` is
* pixels 0 <= x < 50, 110 <= y < 210.
*

* Method to create scenes on the stage. Pass an ID and function to register a scene.
*
* To play a scene, just pass the ID. When a scene is played, all
* previously-created entities with the `2D` component are destroyed. The
* viewport is also reset.
*
* If you want some entities to persist over scenes (as in, not be destroyed)
* simply add the component `Persist`.
*
* @example
* ~~~
* Crafty.scene("loading", function() {
* Crafty.background("#000");
* Crafty.e("2D, DOM, Text")
* .attr({ w: 100, h: 20, x: 150, y: 120 })
* .text("Loading")
* .css({ "text-align": "center"})
* .textColor("#FFFFFF");
* });
*
* Crafty.scene("UFO_dance",
* function() {Crafty.background("#444"); Crafty.e("UFO");},
* function() {...send message to server...});
* ~~~
* This defines (but does not play) two scenes as discussed below.
* ~~~
* Crafty.scene("loading");
* ~~~
* This command will clear the stage by destroying all `2D` entities (except
* those with the `Persist` component). Then it will set the background to
* black and display the text "Loading".
* ~~~
* Crafty.scene("UFO_dance");
* ~~~
* This command will clear the stage by destroying all `2D` entities (except
* those with the `Persist` component). Then it will set the background to
* gray and create a UFO entity. Finally, the next time the game encounters
* another command of the form `Crafty.scene(scene_name)` (if ever), then the
* game will send a message to the server.

* More tips for writing text inside an image: (1) Use the z-index (from 2D component)
* to ensure that the text is on top of the image, not the other way around; (2)
* use .attach() (from 2D component) to glue the text to the image so they move and
* rotate together.
*
* Note 2: For DOM (but not canvas) text entities, various font settings (like
* text-decoration and text-align) can be set using `.css()` (see DOM component). But
* you cannot use `.css()` to set the properties which are controlled by `.textFont()`

Try to resize/zoom in window - tooltip in this sample will try to
magnet to window borders, top left border is priority here. Idea
is following: sometimes you have custom border cases, like custom
scrolls, small windows, iframes, react-tooltip itself can not
cover everything, so up to you if you want to customize default
behavior, or may be just limit it like in this example.

/*
* The observedSet abstraction is a perf optimization which reduces the total
* number of Object.observe observations of a set of objects. The idea is that
* groups of Observers will have some object dependencies in common and this
* observed set ensures that each object in the transitive closure of
* dependencies is only observed once. The observedSet acts as a write barrier
* such that whenever any change comes through, all Observers are checked for
* changed values.
*
* Note that this optimization is explicitly moving work from setup-time to
* change-time.
*
* TODO(rafaelw): Implement "garbage collection". In order to move work off
* the critical path, when Observers are closed, their observed objects are
* not Object.unobserve(d). As a result, it's possible that if the observedSet
* is kept open, but some Observers have been closed, it could cause "leaks"
* (prevent otherwise collectable objects from being collected). At some
* point, we should implement incremental "gc" which keeps a list of
* observedSets which may need clean-up and does small amounts of cleanup on a
* timeout until all is clean.

* The "U" in "CRUD". Update the item of type `resourceName` and primary key `id` with `attrs`. This is useful when you
* want to update an item that isn't already in the data store, or you don't want to update the item that's in the data
* store until the adapter operation succeeds. This differs from `DS.save` which simply saves items in their current
* form that already exist in the data store. The resulting item (by default) will be injected into the data store.
*
* ## Signature:
* ```js
* DS.update(resourceName, id, attrs[, options])
* ```

* ## Example:
*
* ```js
* DS.get('document', 5); // undefined
*
* DS.update('document', 5, {
* title: 'How to cook in style'
* }).then(function (document) {
* document; // A reference to the document that's been saved via an adapter
* // and now resides in the data store
* });
* ```
*
* @param {string} resourceName The resource type, e.g. 'user', 'comment', etc.
* @param {string|number} id The primary key of the item to update.
* @param {object} attrs The attributes with which to update the item.
* @param {object=} options Optional configuration. Also passed along to the adapter's `update` method. Properties:

* - `{boolean=}` - `cacheResponse` - Inject the data returned by the adapter into the data store. Default: `true`.
* - `{function=}` - `beforeValidate` - Override the resource or global lifecycle hook.

* - `{function=}` - `beforeUpdate` - Override the resource or global lifecycle hook.
* - `{function=}` - `afterUpdate` - Override the resource or global lifecycle hook.
*
* @returns {Promise} Promise produced by the `$q` service.

* @doc method
* @id DS.sync methods:defineResource
* @name defineResource
* @description
* Define a resource and register it with the data store.
*
* ## Signature:
* ```js
* DS.defineResource(definition)
* ```
*
* ## Example:
*
* ```js
* DS.defineResource({
* name: 'document',
* idAttribute: '_id',
* endpoint: '/documents
* baseUrl: 'http://myapp.com/api',
* beforeDestroy: function (resourceName attrs, cb) {
* console.log('looks good to me');
* cb(null, attrs);
* }
* });
* ```
*
* ## Throws
*
* - `{IllegalArgumentError}`
* - `{RuntimeError}`
*
* @param {string|object} definition Name of resource or resource definition object: Properties:
*
* - `{string}` - `name` - The name by which this resource will be identified.
* - `{string="id"}` - `idAttribute` - The attribute that specifies the primary key for this resource.
* - `{string=}` - `endpoint` - The attribute that specifies the primary key for this resource. Default is the value of `name`.
* - `{string=}` - `baseUrl` - The url relative to which all AJAX requests will be made.
* - `{boolean=}` - `useClass` - Whether to use a wrapper class created from the ProperCase name of the resource. The wrapper will always be used for resources that have `methods` defined.
* - `{boolean=}` - `keepChangeHistory` - Whether to keep a history of changes for items in the data store. Default: `false`.
* - `{boolean=}` - `resetHistoryOnInject` - Whether to reset the history of changes for items when they are injected of re-injected into the data store. This will also reset an item's previous attributes. Default: `true`.
* - `{function=}` - `defaultFilter` - Override the filtering used internally by `DS.filter` with you own function here.
* - `{*=}` - `meta` - A property reserved for developer use. This will never be used by the API.
* - `{object=}` - `methods` - If provided, items of this resource will be wrapped in a constructor function that is
* empty save for the attributes in this option which will be mixed in to the constructor function prototype. Enabling
* this feature for this resource will incur a slight performance penalty, but allows you to give custom behavior to what
* are now "instances" of this resource.
* - `{function=}` - `beforeValidate` - Lifecycle hook. Overrides global. Signature: `beforeValidate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `validate` - Lifecycle hook. Overrides global. Signature: `validate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `afterValidate` - Lifecycle hook. Overrides global. Signature: `afterValidate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `beforeCreate` - Lifecycle hook. Overrides global. Signature: `beforeCreate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `afterCreate` - Lifecycle hook. Overrides global. Signature: `afterCreate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `beforeUpdate` - Lifecycle hook. Overrides global. Signature: `beforeUpdate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `afterUpdate` - Lifecycle hook. Overrides global. Signature: `afterUpdate(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `beforeDestroy` - Lifecycle hook. Overrides global. Signature: `beforeDestroy(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.
* - `{function=}` - `afterDestroy` - Lifecycle hook. Overrides global. Signature: `afterDestroy(resourceName, attrs, cb)`. Callback signature: `cb(err, attrs)`.

* Inject the given item into the data store as the specified type. If `attrs` is an array, inject each item into the
* data store. Injecting an item into the data store does not save it to the server. Emits a `"DS.inject"` event.
*
* ## Signature:
* ```js
* DS.inject(resourceName, attrs[, options])
* ```
*
* ## Examples:
*
* ```js
* DS.get('document', 45); // undefined
*
* DS.inject('document', { title: 'How to Cook', id: 45 });
*
* DS.get('document', 45); // { title: 'How to Cook', id: 45 }

*
* Inject a collection into the data store:
*
* ```js
* DS.filter('document'); // [ ]
*
* DS.inject('document', [ { title: 'How to Cook', id: 45 }, { title: 'How to Eat', id: 46 } ]);

* ## Examples:
*
* Assume `user` has `hasMany` relationships to `post` and `comment`.
* ```js

* ## Install
*
* #### Bower
* ```text
* bower install angular-data
* ```
*
* Load `dist/angular-data.js` or `dist/angular-data.min.js` onto your web page after Angular.js.
*
* #### Npm
* ```text
* npm install angular-data
* ```
*
* Load `dist/angular-data.js` or `dist/angular-data.min.js` onto your web page after Angular.js.
*
* #### Manual download
* Download angular-data from the [Releases](https://github.com/jmdobry/angular-data/releases)
* section of the angular-data GitHub project.
*
* ## Load into Angular
* Your Angular app must depend on the module `"angular-data.DS"` in order to use angular-data. Loading
* angular-data into your app allows you to inject the following:
*
* - `DS`
* - `DSHttpAdapter`
* - `DSUtils`
* - `DSErrors`
*
* [DS](/documentation/api/api/DS) is the Data Store itself, which you will inject often.
* [DSHttpAdapter](/documentation/api/api/DSHttpAdapter) is useful as a wrapper for `$http` and is configurable.
* [DSUtils](/documentation/api/api/DSUtils) has some useful utility methods.
* [DSErrors](/documentation/api/api/DSErrors) provides references to the various errors thrown by the data store.
