* - `process.nextTick` is only Node.js.

* - Everything else is browser based (e.g., mutation observer, requestAnimationFrame, etc).
* - Only API which is universal is `setTimeout`.
* - Note that `0` is not actually `0ms`. Browser environments commonly have a minimum delay of `4ms`. This is acceptable. Here, the main intent of this function is to give the runtime a chance to run garbage collection, clear state, and tend to any other pending tasks before returning control to benchmark tasks. The larger aim (attainable or not) is to provide each benchmark run with as much of a fresh state as possible.

/**
* Returns an accumulator function which incrementally computes an unbiased sample variance.
*
* ## Method
*
* - This implementation uses Welford's algorithm for efficient computation, which can be derived as follows. Let
*
* ```tex
* \begin{align*}
* S_n &= n \sigma_n^2 \\
* &= \sum_{i=1}^{n} (x_i - \mu_n)^2 \\
* &= \biggl(\sum_{i=1}^{n} x_i^2 \biggr) - n\mu_n^2
* \end{align*}
* ```
*
* Accordingly,
*
* ```tex
* \begin{align*}
* S_n - S_{n-1} &= \sum_{i=1}^{n} x_i^2 - n\mu_n^2 - \sum_{i=1}^{n-1} x_i^2 + (n-1)\mu_{n-1}^2 \\
* &= x_n^2 - n\mu_n^2 + (n-1)\mu_{n-1}^2 \\
* &= x_n^2 - \mu_{n-1}^2 + n(\mu_{n-1}^2 - \mu_n^2) \\
* &= x_n^2 - \mu_{n-1}^2 + n(\mu_{n-1} - \mu_n)(\mu_{n-1} + \mu_n) \\
* &= x_n^2 - \mu_{n-1}^2 + (\mu_{n-1} - x_n)(\mu_{n-1} + \mu_n) \\
* &= x_n^2 - \mu_{n-1}^2 + \mu_{n-1}^2 - x_n\mu_n - x_n\mu_{n-1} + \mu_n\mu_{n-1} \\
* &= x_n^2 - x_n\mu_n - x_n\mu_{n-1} + \mu_n\mu_{n-1} \\
* &= (x_n - \mu_{n-1})(x_n - \mu_n) \\
* &= S_{n-1} + (x_n - \mu_{n-1})(x_n - \mu_n)
* \end{align*}
* ```
*
* where we use the identity
*
* ```tex
* x_n - \mu_{n-1} = n (\mu_n - \mu_{n-1})
* ```

* ## Notes
*
* - In contrast to the built-in `Object.getOwnPropertyNames()`, this function returns an empty array if provided `undefined` or `null`, rather than throwing an error.
* - In environments lacking support for `Object.getOwnPropertyNames()`, property descriptors are unavailable, and thus all properties can be safely assumed to be enumerable. Hence, we can defer to calling `Object.keys`, which retrieves all own enumerable property names.
*
* @private
* @param {*} value - input object
* @returns {Array} a list of own property names
*
* @example
* var obj = {
* 'beep': 'boop',
* 'foo': 3.14
* };
*
* var keys = getOwnPropertyNames( obj );
* // e.g., returns [ 'beep', 'foo' ]
*/

// 2. If that resulting state will trigger a _read, then call _read.

// deeply ugly to write APIs this way, but that still doesn't mean
// that the Readable class should behave improperly, as streams are
// designed to be sync/async agnostic.
// Take note if the _read call is sync or async (ie, if the read call
// has returned yet), so that we know whether or not it's safe to emit

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

* each point whether added by options or methods like series.addPoint.
* - Next, series.data contains those values converted to points, but in case the series data length
* exceeds the cropThreshold, or if the data is grouped, series.data doesn't contain all the points. It
* only contains the points that have been created on demand.
* - Then there's series.points that contains all currently visible point objects. In case of cropping,
* the cropped-away points are not part of this array. The series.points array starts at series.cropStart
* compared to series.data and series.options.data. If however the series data is grouped, these can't
* be correlated one to one.
* - series.xData and series.processedXData contain clean x values, equivalent to series.data and series.points.

This file creates a global JSON object containing two methods: stringify
and parse.
JSON.stringify(value, replacer, space)
value any JavaScript value, usually an object or array.
replacer an optional parameter that determines how object
values are stringified for objects. It can be a
function or an array of strings.
space an optional parameter that specifies the indentation
of nested structures. If it is omitted, the text will
be packed without extra whitespace. If it is a number,
it will specify the number of spaces to indent at each
level. If it is a string (such as '\t' or ' '),
it contains the characters used to indent at each level.
This method produces a JSON text from a JavaScript value.
When an object value is found, if the object contains a toJSON
method, its toJSON method will be called and the result will be
stringified. A toJSON method does not serialize: it returns the
value represented by the name/value pair that should be serialized,
or undefined if nothing should be serialized. The toJSON method
will be passed the key associated with the value, and this will be
bound to the value
For example, this would serialize Dates as ISO strings.
Date.prototype.toJSON = function (key) {
function f(n) {
// Format integers to have at least two digits.
return n < 10 ? '0' + n : n;
}
return this.getUTCFullYear() + '-' +
f(this.getUTCMonth() + 1) + '-' +
f(this.getUTCDate()) + 'T' +
f(this.getUTCHours()) + ':' +
f(this.getUTCMinutes()) + ':' +
f(this.getUTCSeconds()) + 'Z';
};
You can provide an optional replacer method. It will be passed the
key and value of each member, with this bound to the containing
object. The value that is returned from your method will be
serialized. If your method returns undefined, then the member will
be excluded from the serialization.
If the replacer parameter is an array of strings, then it will be
used to select the members to be serialized. It filters the results
such that only members with keys listed in the replacer array are
stringified.
Values that do not have JSON representations, such as undefined or
functions, will not be serialized. Such values in objects will be
dropped; in arrays they will be replaced with null. You can use
a replacer function to replace those with JSON values.
JSON.stringify(undefined) returns undefined.
The optional space parameter produces a stringification of the
value that is filled with line breaks and indentation to make it
easier to read.
If the space parameter is a non-empty string, then that string will
be used for indentation. If the space parameter is a number, then
the indentation will be that many spaces.
Example:
text = JSON.stringify(['e', {pluribus: 'unum'}]);
// text is '["e",{"pluribus":"unum"}]'
text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
// text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
text = JSON.stringify([new Date()], function (key, value) {
return this[key] instanceof Date ?
'Date(' + this[key] + ')' : value;
});
// text is '["Date(---current time---)"]'
JSON.parse(text, reviver)
This method parses a JSON text to produce an object or array.
It can throw a SyntaxError exception.
The optional reviver parameter is a function that can filter and
transform the results. It receives each of the keys and values,
and its return value is used instead of the original value.
If it returns what it received, then the structure is not modified.
If it returns undefined then the member is deleted.
Example:
// Parse the text. Values that look like ISO date strings will
// be converted to Date objects.
myData = JSON.parse(text, function (key, value) {
var a;
if (typeof value === 'string') {
a =
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
if (a) {
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
+a[5], +a[6]));
}
}
return value;
});
myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
var d;
if (typeof value === 'string' &&
value.slice(0, 5) === 'Date(' &&
value.slice(-1) === ')') {
d = new Date(value.slice(5, -1));
if (d) {
return d;
}
}
return value;

// even the surrounding frame which wraps your whole app. Defining a chunk of
// UI as a **View** allows you to define your DOM events declaratively, without
// having to worry about render order ... and makes it easy for the view to
// react to specific changes in the state of your models.

// if an existing element is not provided...

* Summary of `ReactEventEmitter` event handling:
*
* - Top-level delegation is used to trap native browser events. We normalize
* and de-duplicate events to account for browser quirks.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.

* `Transaction` creates a black box that is able to wrap any method such that

* (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 ran while it is already being ran. 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.

* 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 `componentDidRender` 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.

If an Ember.js developer defines a subclass of DS.Store on their application,

Note that this code will only be run if the `ember-application` package is

A ManyArray is a RecordArray that represents the contents of a has-many
relationship.
The ManyArray is instantiated lazily the first time the relationship is

### Inverses
Often, the relationships in Ember Data applications will have
an inverse. For example, imagine the following models are
defined:
App.Post = DS.Model.extend({
comments: DS.hasMany('App.Comment')
});
App.Comment = DS.Model.extend({
post: DS.belongsTo('App.Post')
});
If you created a new instance of `App.Post` and added
a `App.Comment` record to its `comments` has-many
relationship, you would expect the comment's `post`
property to be set to the post that contained
the has-many.
We call the record to which a relationship belongs the
relationship's _owner_.

/**
The Mappable mixin is designed for classes that would like to
behave as a map for configuration purposes.
For example, the DS.Adapter class can behave like a map, with
more semantic API, via the `map` API:
DS.Adapter.map('App.Person', { firstName: { key: 'FIRST' } });
Class configuration via a map-like API has a few common requirements
that differentiate it from the standard Ember.Map implementation.
First, values often are provided as strings that should be normalized
into classes the first time the configuration options are used.
Second, the values configured on parent classes should also be taken
into account.
Finally, setting the value of a key sometimes should merge with the
previous value, rather than replacing it.
This mixin provides a instance method, `createInstanceMapFor`, that
will reify all of the configuration options set on an instance's
constructor and provide it for the instance to use.
Classes can implement certain hooks that allow them to customize
the requirements listed above:
* `resolveMapConflict` - called when a value is set for an existing
value
* `transformMapKey` - allows a key name (for example, a global path
to a class) to be normalized
* `transformMapValue` - allows a value (for example, a class that
should be instantiated) to be normalized
Classes that implement this mixin should also implement a class
method built using the `generateMapFunctionFor` method:
DS.Adapter.reopenClass({
map: DS.Mappable.generateMapFunctionFor('attributes', function(key, newValue, map) {
var existingValue = map.get(key);
for (var prop in newValue) {
if (!newValue.hasOwnProperty(prop)) { continue; }
existingValue[prop] = newValue[prop];
}
})
});
The function passed to `generateMapFunctionFor` is invoked every time a
new value is added to the map.

// * +reference+ means a record reference object, which holds metadata about a
// record, even if it has not yet been fully materialized.
// * +type+ means a subclass of DS.Model.
// Used by the store to normalize IDs entering the store. Despite the fact
// that developers may provide IDs as numbers (e.g., `store.find(Person, 1)`),
// it is important that internally we use strings, since IDs may be serialized
// and lose type information. For example, Ember's router may put a record's

/**
The store contains all of the data for records loaded from the server.
It is also responsible for creating instances of DS.Model that wrap
the individual data for a record, so that they can be bound to in your
Handlebars templates.
Define your application's store like this:
MyApp.Store = DS.Store.extend();
Most Ember.js applications will only have a single `DS.Store` that is
automatically created by their `Ember.Application`.
You can retrieve models from the store in several ways. To retrieve a record
for a specific id, use `DS.Model`'s `find()` method:
var person = App.Person.find(123);
If your application has multiple `DS.Store` instances (an unusual case), you can
specify which store should be used:
var person = store.find(App.Person, 123);
In general, you should retrieve models using the methods on `DS.Model`; you should
rarely need to interact with the store directly.
By default, the store will talk to your backend using a standard REST mechanism.
You can customize how the store talks to your backend by specifying a custom adapter:
MyApp.store = DS.Store.create({
adapter: 'MyApp.CustomAdapter'
});
You can learn more about writing a custom adapter by reading the `DS.Adapter`
documentation.

WARNING: Much of these docs are inaccurate as of bf8497.
This file encapsulates the various states that a record can transition
through during its lifecycle.
### State Manager
A record's state manager explicitly tracks what state a record is in
at any given time. For instance, if a record is newly created and has
not yet been sent to the adapter to be saved, it would be in the
`created.uncommitted` state. If a record has had local modifications
made to it that are in the process of being saved, the record would be
in the `updated.inFlight` state. (These state paths will be explained
in more detail below.)
Events are sent by the record or its store to the record's state manager.
How the state manager reacts to these events is dependent on which state
it is in. In some states, certain events will be invalid and will cause
an exception to be raised.
States are hierarchical. For example, a record can be in the
`deleted.start` state, then transition into the `deleted.inFlight` state.
If a child state does not implement an event handler, the state manager
will attempt to invoke the event on all parent states until the root state is
reached. The state hierarchy of a record is described in terms of a path
string. You can determine a record's current state by getting its manager's
current state path:
record.get('stateManager.currentPath');
//=> "created.uncommitted"
The `DS.Model` states are themselves stateless. What we mean is that,
though each instance of a record also has a unique instance of a
`DS.StateManager`, the hierarchical states that each of *those* points
to is a shared data structure. For performance reasons, instead of each
record getting its own copy of the hierarchy of states, each state
manager points to this global, immutable shared instance. How does a
state know which record it should be acting on? We pass a reference to
the current state manager as the first parameter to every method invoked
on a state.
The state manager passed as the first parameter is where you should stash
state about the record if needed; you should never store data on the state
object itself. If you need access to the record being acted on, you can
retrieve the state manager's `record` property. For example, if you had
an event handler `myEvent`:
myEvent: function(manager) {
var record = manager.get('record');
record.doSomething();
}
For more information about state managers in general, see the Ember.js
documentation on `Ember.StateManager`.
### Events, Flags, and Transitions
A state may implement zero or more events, flags, or transitions.
#### Events
Events are named functions that are invoked when sent to a record. The
state manager will first look for a method with the given name on the
current state. If no method is found, it will search the current state's
parent, and then its grandparent, and so on until reaching the top of
the hierarchy. If the root is reached without an event handler being found,
an exception will be raised. This can be very helpful when debugging new
features.
Here's an example implementation of a state with a `myEvent` event handler:
aState: DS.State.create({
myEvent: function(manager, param) {
console.log("Received myEvent with "+param);
}
})
To trigger this event:
record.send('myEvent', 'foo');
//=> "Received myEvent with foo"
Note that an optional parameter can be sent to a record's `send()` method,
which will be passed as the second parameter to the event handler.
Events should transition to a different state if appropriate. This can be
done by calling the state manager's `transitionTo()` method with a path to the
desired state. The state manager will attempt to resolve the state path
relative to the current state. If no state is found at that path, it will
attempt to resolve it relative to the current state's parent, and then its
parent, and so on until the root is reached. For example, imagine a hierarchy
like this:
* created
* start <-- currentState
* inFlight
* updated
* inFlight
If we are currently in the `start` state, calling
`transitionTo('inFlight')` would transition to the `created.inFlight` state,
while calling `transitionTo('updated.inFlight')` would transition to
the `updated.inFlight` state.
Remember that *only events* should ever cause a state transition. You should
never call `transitionTo()` from outside a state's event handler. If you are
tempted to do so, create a new event and send that to the state manager.
#### Flags
Flags are Boolean values that can be used to introspect a record's current
state in a more user-friendly way than examining its state path. For example,
instead of doing this:
var statePath = record.get('stateManager.currentPath');
if (statePath === 'created.inFlight') {
doSomething();
}
You can say:
if (record.get('isNew') && record.get('isSaving')) {
doSomething();
}
If your state does not set a value for a given flag, the value will
be inherited from its parent (or the first place in the state hierarchy
where it is defined).
The current set of flags are defined below. If you want to add a new flag,
in addition to the area below, you will also need to declare it in the
`DS.Model` class.
#### Transitions
Transitions are like event handlers but are called automatically upon
entering or exiting a state. To implement a transition, just call a method
either `enter` or `exit`:
myState: DS.State.create({
// Gets called automatically when entering
// this state.
enter: function(manager) {
console.log("Entered myState");
}
})
Note that enter and exit events are called once per transition. If the
current state changes, but changes to another child state of the parent,
the transition event on the parent will not be triggered.

//
// Each state has a boolean value for all of the following flags:
//
// * isLoaded: The record has a populated `data` property. When a
// record is loaded via `store.find`, `isLoaded` is false
// until the adapter sets it. When a record is created locally,
// its `isLoaded` property is always true.
// * isDirty: The record has local changes that have not yet been
// saved by the adapter. This includes records that have been
// created (but not yet saved) or deleted.
// * isSaving: The record has been committed, but
// the adapter has not yet acknowledged that the changes have
// been persisted to the backend.
// * isDeleted: The record was marked for deletion. When `isDeleted`
// is true and `isDirty` is true, the record is deleted locally
// but the deletion was not yet persisted. When `isSaving` is
// true, the change is in-flight. When both `isDirty` and
// `isSaving` are false, the change has persisted.
// * isError: The adapter reported that it was unable to save
// local changes to the backend. This may also result in the
// record having its `isValid` property become false if the
// adapter reported that server-side validations failed.
// * isNew: The record was created on the client and the adapter
// did not yet report that it was successfully saved.
// * isValid: No client-side validations have failed and the
// adapter did not report any server-side validation failures.
// The dirty state is a abstract state whose functionality is
// shared between the `created` and `updated` states.
//
// The deleted state shares the `isDirty` flag with the
// subclasses of `DirtyState`, but with a very different
// implementation.
//
// Dirty states have three child states:
//
// `uncommitted`: the store has not yet handed off the record

/**
An adapter is an object that receives requests from a store and
translates them into the appropriate action to take against your
persistence layer. The persistence layer is usually an HTTP API, but may
be anything, such as the browser's local storage.
### Creating an Adapter
First, create a new subclass of `DS.Adapter`:
App.MyAdapter = DS.Adapter.extend({
// ...your code here
});
To tell your store which adapter to use, set its `adapter` property:
App.store = DS.Store.create({
adapter: App.MyAdapter.create()
});
`DS.Adapter` is an abstract base class that you should override in your
application to customize it for your backend. The minimum set of methods
that you should implement is:
* `find()`
* `createRecord()`
* `updateRecord()`
* `deleteRecord()`
To improve the network performance of your application, you can optimize
your adapter by overriding these lower-level methods:
* `findMany()`
* `createRecords()`
* `updateRecords()`
* `deleteRecords()`
* `commit()`
For an example implementation, see `DS.RestAdapter`, the
included REST adapter.
@class Adapter
@namespace DS
@extends Ember.Object
@uses DS._Mappable
*/
DS.Adapter = Ember.Object.extend(DS._Mappable, {
/**
The `find()` method is invoked when the store is asked for a record that
has not previously been loaded. In response to `find()` being called, you
should query your persistence layer for a record with the given ID. Once
found, you can asynchronously call the store's `load()` method to load
the record.
Here is an example `find` implementation:
find: function(store, type, id) {
var url = type.url;
url = url.fmt(id);
jQuery.getJSON(url, function(data) {
// data is a hash of key/value pairs. If your server returns a
// root, simply do something like:
// store.load(type, id, data.person)
store.load(type, id, data);
});

If the globally unique IDs for your records should be generated on the client,

Most traditional REST-like HTTP APIs will not use this method. Instead, the ID
of the record will be set by the server, and your adapter will update the store
with the new ID when it calls `didCreateRecord()`. Only implement this method if
you intend to generate record IDs on the client-side.
The `generateIdForRecord()` method will be invoked with the requesting store as
the first parameter and the newly created record as the second parameter:

Normalizes a part of the JSON payload returned by
the server. You should override this method, munge the hash
and call super if you have generic normalization to do.
It takes the type of the record that is being normalized
(as a DS.Model class), the property where the hash was
originally found, and the hash to normalize.
For example, if you have a payload that looks like this:
```js
{
"post": {
"id": 1,
"title": "Rails is omakase",
"comments": [ 1, 2 ]
},
"comments": [{
"id": 1,
"body": "FIRST"
}, {
"id": 2,
"body": "Rails is unagi"
}]
}
```
The `normalize` method will be called three times:
* With `App.Post`, `"posts"` and `{ id: 1, title: "Rails is omakase", ... }`
* With `App.Comment`, `"comments"` and `{ id: 1, body: "FIRST" }`
* With `App.Comment`, `"comments"` and `{ id: 2, body: "Rails is unagi" }`
You can use this method, for example, to normalize underscored keys to camelized
or other general-purpose normalizations.
If you want to do normalizations specific to some part of the payload, you
can specify those under `normalizeHash`.
For example, if the `IDs` under `"comments"` are provided as `_id` instead of
`id`, you can specify how to normalize just the comments:
```js
App.PostSerializer = DS.RESTSerializer.extend({
normalizeHash: {
comments: function(hash) {
hash.id = hash._id;
delete hash._id;
return hash;
}
}
});
```
The key under `normalizeHash` is just the original key that was in the original
payload.

It is your opportunity to clean up the server's response into the normalized

do more fine-grained normalization in the `normalize` method.
For example, if you have a payload like this in response to a request for

"comment": [{
"_id": 1,
"comment_title": "FIRST"
}, {
"_id": 2,
"comment_title": "Rails is unagi"

}
}
```
You could implement a serializer that looks like this to get your payload
into shape:
```js
App.PostSerializer = DS.RESTSerializer.extend({
// First, restructure the top-level so it's organized by type
extractSingle: function(store, type, payload, id, requestType) {
var comments = payload._embedded.comment;
delete payload._embedded;
payload = { comments: comments, post: payload };

},

// Next, normalize individual comments, which (after `extract`)

comments: function(hash) {
hash.id = hash._id;
hash.title = hash.comment_title;
delete hash._id;
delete hash.comment_title;
return hash;
}
}
})
```
When you call super from your own implementation of `extractSingle`, the
built-in implementation will find the primary record in your normalized
payload and push the remaining records into the store.
The primary record is the single hash found under `post` or the first
element of the `posts` array.
The primary record has special meaning when the record is being created
for the first time or updated (`createRecord` or `updateRecord`). In
particular, it will update the properties of the record that was saved.

// SERIALIZE
/**
Called when a record is saved in order to convert the
record into JSON.
By default, it creates a JSON object with a key for
each attribute and belongsTo relationship.
For example, consider this model:
```js
App.Comment = DS.Model.extend({
title: DS.attr(),
body: DS.attr(),
author: DS.belongsTo('user')
});
```
The default serialization would create a JSON object like:
```js
{
"title": "Rails is unagi",
"body": "Rails? Omakase? O_O",
"author": 12
}
```
By default, attributes are passed through as-is, unless
you specified an attribute type (`DS.attr('date')`). If
you specify a transform, the JavaScript value will be
serialized when inserted into the JSON hash.
By default, belongs-to relationships are converted into
IDs when inserted into the JSON hash.
## IDs
`serialize` takes an options hash with a single option:
`includeId`. If this option is `true`, `serialize` will,
by default include the ID in the JSON object it builds.
The adapter passes in `includeId: true` when serializing
a record for `createRecord`, but not for `updateRecord`.
## Customization
Your server may expect a different JSON format than the
built-in serialization format.
In that case, you can implement `serialize` yourself and
return a JSON hash of your choosing.
```js
App.PostSerializer = DS.RESTSerializer.extend({
serialize: function(post, options) {
var json = {
POST_TTL: post.get('title'),
POST_BDY: post.get('body'),
POST_CMS: post.get('comments').mapProperty('id')
}
if (options.includeId) {
json.POST_ID_ = post.get('id');
}
return json;
}
});
```
## Customizing an App-Wide Serializer
If you want to define a serializer for your entire
application, you'll probably want to use `eachAttribute`
and `eachRelationship` on the record.
```js
App.ApplicationSerializer = DS.RESTSerializer.extend({
serialize: function(record, options) {
var json = {};
record.eachAttribute(function(name) {
json[serverAttributeName(name)] = record.get(name);
})
record.eachRelationship(function(name, relationship) {
if (relationship.kind === 'hasMany') {
json[serverHasManyName(name)] = record.get(name).mapBy('id');
}
});
if (options.includeId) {
json.ID_ = record.get('id');
}
return json;
}
});
function serverAttributeName(attribute) {
return attribute.underscore().toUpperCase();
}
function serverHasManyName(name) {
return serverAttributeName(name.singularize()) + "_IDS";
}
```
This serializer will generate JSON that looks like this:
```js
{
"TITLE": "Rails is omakase",
"BODY": "Yep. Omakase.",
"COMMENT_IDS": [ 1, 2, 3 ]
}
```
## Tweaking the Default JSON
If you just want to do some small tweaks on the default JSON,
you can call super first and make the tweaks on the returned
JSON.
```js
App.PostSerializer = DS.RESTSerializer.extend({
serialize: function(record, options) {
var json = this._super(record, options);
json.subject = json.title;
delete json.title;
return json;
}
});
```
*/
serialize: function(record, options) {
return this._super.apply(this, arguments);
}
});
/**
The REST adapter allows your store to communicate with an HTTP server by
transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
should use the REST adapter.
This adapter is designed around the idea that the JSON exchanged with
the server should be conventional.
## JSON Structure
The REST adapter expects the JSON returned from your server to follow
these conventions.
### Object Root
The JSON payload should be an object that contains the record inside a
root property. For example, in response to a `GET` request for
`/posts/1`, the JSON should look like this:
```js
{
"post": {
title: "I'm Running to Reform the W3C's Tag",
author: "Yehuda Katz"
}
}
```
### Conventional Names
Attribute names in your JSON payload should be the underscored versions of
the attributes in your Ember.js models.
For example, if you have a `Person` model:
```js
App.Person = DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
occupation: DS.attr('string')
});
```
The JSON returned should look like this:
```js
{
"person": {
"first_name": "Barack",
"last_name": "Obama",
"occupation": "President"
}
}
```
## Customization
### Endpoint path customization
Endpoint paths can be prefixed with a `namespace` by setting the namespace
property on the adapter:
```js
DS.RESTAdapter.reopen({
namespace: 'api/1'
});
```
Requests for `App.Person` would now target `/api/1/people/1`.
### Host customization
An adapter can target other hosts by setting the `url` property.
```js
DS.RESTAdapter.reopen({
url: 'https://api.example.com'
});
```
### Headers customization
Some APIs require HTTP headers, eg to provide an API key. An array of
headers can be added to the adapter which are passed with every request:
```js
DS.RESTAdapter.reopen({
headers: {
"API_KEY": "secret key",
"ANOTHER_HEADER": "asdsada"
}

* [Create one now](https://www.algolia.com/users/sign_up).
* @propType {string} indexName - Main index in which to search.
* @propType {boolean} [refresh=false] - Flag to activate when the cache needs to be cleared so that the front-end is updated when a change occurs in the index.
* @propType {object} [searchClient] - Provide a custom search client.
* @propType {func} [onSearchStateChange] - Function to be called everytime a new search is done. Useful for [URL Routing](guide/Routing.html).
* @propType {object} [searchState] - Object to inject some search state. Switches the InstantSearch component in controlled mode. Useful for [URL Routing](guide/Routing.html).
* @propType {func} [createURL] - Function to call when creating links, useful for [URL Routing](guide/Routing.html).
* @propType {SearchResults|SearchResults[]} [resultsState] - Use this to inject the results that will be used at first rendering. Those results are found by using the `findResultsState` function. Useful for [Server Side Rendering](guide/Server-side_rendering.html).
* @propType {number} [stalledSearchDelay=200] - The amount of time before considering that the search takes too much time. The time is expressed in milliseconds.
* @propType {{ Root: string|function, props: object }} [root] - Use this to customize the root element. Default value: `{ Root: 'div' }`

/**
* A breadcrumb is a secondary navigation scheme that allows the user to see where the current page
* is in relation to the website or web application’s hierarchy.
* In terms of usability, using a breadcrumb reduces the number of actions a visitor needs to take in
* order to get to a higher-level page.
*
* If you want to select a specific refinement for your Breadcrumb component, you will need to
* use a [Virtual Hierarchical Menu](https://community.algolia.com/react-instantsearch/guide/Virtual_widgets.html)
* and set its defaultRefinement that will be then used by the Breadcrumb.
*
* @name Breadcrumb
* @kind widget
* @requirements Breadcrumbs are used for websites with a large amount of content organised in a hierarchical manner.
* The typical example is an e-commerce website which has a large variety of products grouped into logical categories
* (with categories, subcategories which also have subcategories).To use this widget, your attributes must be formatted in a specific way.
*
* Keep in mind that breadcrumbs shouldn’t replace effective primary navigation menus:
* it is only an alternative way to navigate around the website.
*
* If, for instance, you would like to have a breadcrumb of categories, objects in your index
* should be formatted this way:
*
* ```json
* {
* "categories.lvl0": "products",
* "categories.lvl1": "products > fruits",
* "categories.lvl2": "products > fruits > citrus"
* }
* ```
*
* It's also possible to provide more than one path for each level:
*
* ```json
* {
* "categories.lvl0": ["products", "goods"],
* "categories.lvl1": ["products > fruits", "goods > to eat"]
* }
* ```
*
* All attributes passed to the `attributes` prop must be present in "attributes for faceting"
* on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
*
* @propType {array.<string>} attributes - List of attributes to use to generate the hierarchy of the menu. See the example for the convention to follow
* @propType {node} [separator='>'] - Symbol used for separating hyperlinks
* @propType {string} [rootURL=null] - The originating page (homepage)
* @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return
* @themeKey ais-Breadcrumb - the root div of the widget
* @themeKey ais-Breadcrumb--noRefinement - the root div of the widget when there is no refinement
* @themeKey ais-Breadcrumb-list - the list of all breadcrumb items
* @themeKey ais-Breadcrumb-item - the breadcrumb navigation item
* @themeKey ais-Breadcrumb-item--selected - the selected breadcrumb item
* @themeKey ais-Breadcrumb-separator - the separator of each breadcrumb item
* @themeKey ais-Breadcrumb-link - the clickable breadcrumb element
* @translationKey rootLabel - The root's label. Accepts a string
* @example
* import React from 'react';
* import algoliasearch from 'algoliasearch/lite';
* import { Breadcrumb, InstantSearch, HierarchicalMenu } from 'react-instantsearch-dom';
*
* const searchClient = algoliasearch(

/**
* The hierarchical menu lets the user browse attributes using a tree-like structure.
*
* This is commonly used for multi-level categorization of products on e-commerce
* websites. From a UX point of view, we suggest not displaying more than two levels deep.
*
* @name HierarchicalMenu
* @kind widget
* @requirements To use this widget, your attributes must be formatted in a specific way.
* If you want for example to have a hiearchical menu of categories, objects in your index
* should be formatted this way:
*
* ```json
* [{
* "objectID": "321432",
* "name": "lemon",
* "categories.lvl0": "products",
* "categories.lvl1": "products > fruits",
* },
* {
* "objectID": "8976987",
* "name": "orange",
* "categories.lvl0": "products",
* "categories.lvl1": "products > fruits",
* }]
* ```
*
* It's also possible to provide more than one path for each level:
*
* ```json
* {
* "objectID": "321432",
* "name": "lemon",
* "categories.lvl0": ["products", "goods"],
* "categories.lvl1": ["products > fruits", "goods > to eat"]
* }
* ```
*
* All attributes passed to the `attributes` prop must be present in "attributes for faceting"
* on the Algolia dashboard or configured as `attributesForFaceting` via a set settings call to the Algolia API.
*
* @propType {array.<string>} attributes - List of attributes to use to generate the hierarchy of the menu. See the example for the convention to follow.
* @propType {boolean} [showMore=false] - Flag to activate the show more button, for toggling the number of items between limit and showMoreLimit.
* @propType {number} [limit=10] - The maximum number of items displayed.
* @propType {number} [showMoreLimit=20] - The maximum number of items displayed when the user triggers the show more. Not considered if `showMore` is false.
* @propType {string} [separator='>'] - Specifies the level separator used in the data.
* @propType {string} [rootPath=null] - The path to use if the first level is not the root level.
* @propType {boolean} [showParentLevel=true] - Flag to set if the parent level should be displayed.
* @propType {string} [defaultRefinement] - the item value selected by default
* @propType {function} [transformItems] - Function to modify the items being displayed, e.g. for filtering or sorting them. Takes an items as parameter and expects it back in return.
* @themeKey ais-HierarchicalMenu - the root div of the widget
* @themeKey ais-HierarchicalMenu-noRefinement - the root div of the widget when there is no refinement
* @themeKey ais-HierarchicalMenu-searchBox - the search box of the widget. See [the SearchBox documentation](widgets/SearchBox.html#classnames) for the classnames and translation keys of the SearchBox.
* @themeKey ais-HierarchicalMenu-list - the list of menu items
* @themeKey ais-HierarchicalMenu-list--child - the child list of menu items
* @themeKey ais-HierarchicalMenu-item - the menu list item
* @themeKey ais-HierarchicalMenu-item--selected - the selected menu list item
* @themeKey ais-HierarchicalMenu-item--parent - the menu list item containing children
* @themeKey ais-HierarchicalMenu-link - the clickable menu element
* @themeKey ais-HierarchicalMenu-label - the label of each item
* @themeKey ais-HierarchicalMenu-count - the count of values for each item
* @themeKey ais-HierarchicalMenu-showMore - the button used to display more categories
* @themeKey ais-HierarchicalMenu-showMore--disabled - the disabled button used to display more categories
* @translationKey showMore - The label of the show more button. Accepts one parameter, a boolean that is true if the values are expanded
* @example
* import React from 'react';
* import algoliasearch from 'algoliasearch/lite';
* import { InstantSearch, HierarchicalMenu } from 'react-instantsearch-dom';
