  /**
    An `Ember.Binding` connects the properties of two objects so that whenever
    the value of one property changes, the other property will be changed also.
  
    ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
  
    You do not usually create Binding objects directly but instead describe
    bindings in your class or object definition using automatic binding
    detection.
  
    Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
    instances. The value of this property should be a string representing a path
    to another object or a custom binding instance created using Binding helpers
    (see "One Way Bindings"):
  
    ```
    valueBinding: "MyApp.someController.title"
    ```
  
    This will create a binding from `MyApp.someController.title` to the `value`
    property of your object instance automatically. Now the two values will be
    kept in sync.
  
    ## One Way Bindings
  
    One especially useful binding customization you can use is the `oneWay()`
    helper. This helper tells Ember that you are only interested in
    receiving changes on the object you are binding from. For example, if you
    are binding to a preference and you want to be notified if the preference
    has changed, but your object will not be changing the preference itself, you
    could do:
  
    ```
    bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
    ```
  
    This way if the value of `MyApp.preferencesController.bigTitles` changes the
    `bigTitles` property of your object will change also. However, if you
    change the value of your `bigTitles` property, it will not update the
    `preferencesController`.
  
    One way bindings are almost twice as fast to setup and twice as fast to
    execute because the binding only has to worry about changes to one side.
  
    You should consider using one way bindings anytime you have an object that
    may be created frequently and you do not intend to change a property; only
    to monitor it for changes (such as in the example above).
  
    ## Adding Bindings Manually
  
    All of the examples above show you how to configure a custom binding, but the
    result of these customizations will be a binding template, not a fully active
    Binding instance. The binding will actually become active only when you
    instantiate the object the binding belongs to. It is useful however, to
    understand what actually happens when the binding is activated.
  
    For a binding to function it must have at least a `from` property and a `to`
    property. The `from` property path points to the object/key that you want to
    bind from while the `to` path points to the object/key you want to bind to.
  
    When you define a custom binding, you are usually describing the property
    you want to bind from (such as `MyApp.someController.value` in the examples
    above). When your object is created, it will automatically assign the value
    you want to bind `to` based on the name of your binding key. In the
    examples above, during init, Ember objects will effectively call
    something like this on your binding:
  
    ```javascript
    binding = Ember.Binding.from("valueBinding").to("value");
    ```
  
    This creates a new binding instance based on the template you provide, and
    sets the to path to the `value` property of the new object. Now that the
    binding is fully configured with a `from` and a `to`, it simply needs to be
    connected to become active. This is done through the `connect()` method:
  
    ```javascript
    binding.connect(this);
    ```
  
    Note that when you connect a binding you pass the object you want it to be
    connected to. This object will be used as the root for both the from and
    to side of the binding when inspecting relative paths. This allows the
    binding to be automatically inherited by subclassed objects as well.
  
    This also allows you to bind between objects using the paths you declare in
    `from` and `to`:
  
    ```javascript
    // Example 1
    binding = Ember.Binding.from("App.someObject.value").to("value");
    binding.connect(this);
  
    // Example 2
    binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
    binding.connect(this);
    ```
  
    Now that the binding is connected, it will observe both the from and to side
    and relay changes.
  
    If you ever needed to do so (you almost never will, but it is useful to
    understand this anyway), you could manually create an active binding by
    using the `Ember.bind()` helper method. (This is the same method used by
    to setup your bindings on objects):
  
    ```javascript
    Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
    ```
  
    Both of these code fragments have the same effect as doing the most friendly
    form of binding creation like so:
  
    ```javascript
    MyApp.anotherObject = Ember.Object.create({
      valueBinding: "MyApp.someController.value",
  
      // OTHER CODE FOR THIS OBJECT...
    });
    ```
  
    Ember's built in binding creation method makes it easy to automatically
    create bindings for you. You should always use the highest-level APIs
    available, even if you understand how it works underneath.

  // ..........................................................
  // COMPUTED PROPERTY
  //

  /**
    A computed property transforms an object's function into a property.
  
    By default the function backing the computed property will only be called
    once and the result will be cached. You can specify various properties
    that your computed property depends on. This will force the cached
    result to be recomputed if the dependencies are modified.
  
    In the following example we declare a computed property (by calling
    `.property()` on the fullName function) and setup the property
    dependencies (depending on firstName and lastName). The fullName function
    will be called once (regardless of how many times it is accessed) as long
    as its dependencies have not changed. Once firstName or lastName are updated
    any future calls (or anything bound) to fullName will incorporate the new
    values.
  
    ```javascript
    var Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: function() {
        var firstName = this.get('firstName');
        var lastName = this.get('lastName');
  
       return firstName + ' ' + lastName;
      }.property('firstName', 'lastName')
    });
  
    var tom = Person.create({
      firstName: 'Tom',
      lastName: 'Dale'
    });
  
    tom.get('fullName') // 'Tom Dale'
    ```
  
    You can also define what Ember should do when setting a computed property.
    If you try to set a computed property, it will be invoked with the key and
    value you want to set it to. You can also accept the previous value as the
    third parameter.
  
    ```javascript
    var Person = Ember.Object.extend({
      // these will be supplied by `create`
      firstName: null,
      lastName: null,
  
      fullName: function(key, value, oldValue) {
        // getter
        if (arguments.length === 1) {
          var firstName = this.get('firstName');
          var lastName = this.get('lastName');
  
          return firstName + ' ' + lastName;
  
        // setter
        } else {

  /**
    This helper returns a new property descriptor that wraps the passed
    computed property function. You can use this helper to define properties
    with mixins or via `Ember.defineProperty()`.
  
    The function you pass will be used to both get and set property values.
    The function should accept two parameters, key and value. If value is not
    undefined you should set the value first. In either case return the
    current value of the property.
  
    A computed property defined in this way might look like this:
  
    ```js
    var Person = Ember.Object.extend({
      firstName: 'Betty',
      lastName: 'Jones',
  
      fullName: Ember.computed('firstName', 'lastName', function(key, value) {

    client.set('lastName', 'Fuller');

    ```
  
    _Note: This is the preferred way to define computed properties when writing third-party
    libraries that depend on or use Ember, since there is no guarantee that the user

    [Prototype Extensions](http://emberjs.com/guides/configuring-ember/disabling-prototype-extensions/).

    (if prototype extensions are enabled, which is the default behavior):

  /**
    The purpose of the Ember Instrumentation module is
    to provide efficient, general-purpose instrumentation
    for Ember.
  
    Subscribe to a listener by using `Ember.subscribe`:
  
    ```javascript
    Ember.subscribe("render", {
      before: function(name, timestamp, payload) {
  
      },
  
      after: function(name, timestamp, payload) {
  
      }
    });
    ```
  
    If you return a value from the `before` callback, that same
    value will be passed as a fourth parameter to the `after`
    callback.
  
    Instrument a block of code by using `Ember.instrument`:
  
    ```javascript
    Ember.instrument("render.handlebars", payload, function() {
      // rendering logic
    }, binding);
    ```
  
    Event names passed to `Ember.instrument` are namespaced
    by periods, from more general to more specific. Subscribers
    can listen for events by whatever level of granularity they
    are interested in.
  
    In the above example, the event is `render.handlebars`,
    and the subscriber listened for all events beginning with
    `render`. It would receive callbacks for events named
    `render`, `render.handlebars`, `render.container`, or
    even `render.handlebars.layout`.

  JavaScript (before ES6) does not have a Map implementation. Objects,
  which are often used as dictionaries, may only have Strings as keys.

  Because Ember has a way to get a unique identifier for every object
  via `Ember.guidFor`, we can implement a performant Map with arbitrary
  keys. Because it is commonly used in low-level bookkeeping, Map is
  implemented as a pure JavaScript object for performance.

  This implementation follows the current iteration of the ES6 proposal for
  maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
  with one exception:  as we do not have the luxury of in-VM iteration, we implement a
  forEach method for iteration.

  Map is mocked out to look like an Ember object, so you can do
  `Ember.Map.create()` for symmetry with other Ember classes.

    The `Ember.Mixin` class allows you to create mixins, whose properties can be
    added to other classes. For instance,
  
    ```javascript
    App.Editable = Ember.Mixin.create({
      edit: function() {
        console.log('starting to edit');
        this.set('isEditing', true);
      },
      isEditing: false
    });
  
    // Mix mixins into classes by passing them as the first arguments to
    // .extend.
    App.CommentView = Ember.View.extend(App.Editable, {
      template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
    });
  
    commentView = App.CommentView.create();
    commentView.edit(); // outputs 'starting to edit'
    ```
  
    Note that Mixins are created with `Ember.Mixin.create`, not
    `Ember.Mixin.extend`.
  
    Note that mixins extend a constructor's prototype so arrays and object literals
    defined as properties will be shared amongst objects that implement the mixin.
    If you want to define a property in a mixin that is not shared, you can define
    it either as a computed property or have it be created on initialization of the object.
  
    ```javascript
    //filters array will be shared amongst any object implementing mixin
    App.Filterable = Ember.Mixin.create({
      filters: Ember.A()
    });
  
    //filters will be a separate  array for every object implementing the mixin
    App.Filterable = Ember.Mixin.create({
      filters: Ember.computed(function() {return Ember.A();})
    });
  
    //filters will be created as a separate array during the object's initialization
    App.Filterable = Ember.Mixin.create({
      init: function() {
        this._super.apply(this, arguments);
        this.set("filters", Ember.A());

    NOTE: This is a low-level method used by other parts of the API. You almost
    never want to call this method directly. Instead you should use
    `Ember.mixin()` to define new properties.
  
    Defines a property on an object. This method works much like the ES5
    `Object.defineProperty()` method except that it can also accept computed
    properties and other special descriptors.
  
    Normally this method takes only three parameters. However if you pass an
    instance of `Descriptor` as the third param then you can pass an
    optional value as the fourth parameter. This is often more efficient than
    creating new descriptor hashes for each property.
  
    ## Examples
  
    ```javascript
    // ES5 compatible mode
    Ember.defineProperty(contact, 'firstName', {
      writable: true,
      configurable: false,
      enumerable: true,
      value: 'Charles'
    });
  
    // define a simple property
    Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
  
    // define a computed property
    Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
      return this.firstName+' '+this.lastName;
    }).property('firstName', 'lastName'));
    ```
  
    @private
    @method defineProperty
    @for Ember
    @param {Object} obj the object to define this property on. This may be a prototype.
    @param {String} keyName the name of the property
    @param {Descriptor} [desc] an instance of `Descriptor` (typically a
      computed property) or an ES5 descriptor.
      You must provide this or `data` but not both.
    @param {*} [data] something other than a descriptor, that will
      become the explicit value of this property.

    Allows you to specify which context to call the specified function in while
    adding the execution of that function to the Ember run loop. This ability
    makes this method a great way to asynchronously integrate third-party libraries
    into your Ember application.
  
    `run.bind` takes two main arguments, the desired context and the function to
    invoke in that context. Any additional arguments will be supplied as arguments
    to the function that is passed in.
  
    Let's use the creation of a TinyMCE component as an example. Currently,
    TinyMCE provides a setup configuration option we can use to do some processing
    after the TinyMCE instance is initialized but before it is actually rendered.
    We can use that setup option to do some additional setup for our component.
    The component itself could look something like the following:
  
    ```javascript
    App.RichTextEditorComponent = Ember.Component.extend({
      initializeTinyMCE: Ember.on('didInsertElement', function() {
        tinymce.init({
          selector: '#' + this.$().prop('id'),
          setup: Ember.run.bind(this, this.setupEditor)
        });
      }),
  
      setupEditor: function(editor) {
        this.set('editor', editor);
  
        editor.on('change', function() {
          console.log('content changed!');
        });
      }
    });
    ```
  
    In this example, we use Ember.run.bind to bind the setupEditor method to the
    context of the App.RichTextEditorComponent and to have the invocation of that
    method be safely handled and executed by the Ember run loop.
  
    @method bind
    @namespace Ember
    @param {Object} [target] target of method to call
    @param {Function|String} method Method to invoke.

    not prevent additional calls with an identical anonymous function from
    scheduling the items multiple times, e.g.:
  
    ```javascript
    function scheduleIt() {
      run.scheduleOnce('actions', myContext, function() {

  /**
    Schedules an item to run from within a separate run loop, after
    control has been returned to the system. This is equivalent to calling
    `run.later` with a wait time of 1ms.
  
    ```javascript
    run.next(myContext, function() {
      // code to be executed in the next run loop,
      // which will be scheduled after the current one
    });
    ```
  
    Multiple operations scheduled with `run.next` will coalesce
    into the same later run loop, along with any other operations
    scheduled by `run.later` that expire right around the same
    time that `run.next` operations will fire.
  
    Note that there are often alternatives to using `run.next`.
    For instance, if you'd like to schedule an operation to happen
    after all DOM element operations have completed within the current
    run loop, you can make use of the `afterRender` run loop queue (added
    by the `ember-views` package, along with the preceding `render` queue
    where all the DOM element operations happen). Example:
  
    ```javascript
    App.MyCollectionView = Ember.CollectionView.extend({
      didInsertElement: function() {
        run.scheduleOnce('afterRender', this, 'processChildElements');
      },
      processChildElements: function() {
        // ... do something with collectionView's child view
        // elements after they've finished rendering, which
        // can't be done within the CollectionView's
        // `didInsertElement` hook because that gets run
        // before the child elements have been added to the DOM.
      }
    });
    ```
  
    One benefit of the above approach compared to using `run.next` is
    that you will be able to perform DOM/CSS operations before unprocessed
    elements are rendered to the screen, which may prevent flickering or
    other artifacts caused by delaying processing until after rendering.
  
    The other major benefit to the above approach is that `run.next`
    introduces an element of non-determinism, which can make things much
    harder to test, due to its reliance on `setTimeout`; it's much harder
    to guarantee the order of scheduled operations when they are scheduled
    outside of the current run loop, i.e. with `run.next`.

    This method should be used when an event may be called multiple times
    but the action should only be called once when the event is done firing.
    A common example is for scroll events where you only want updates to

   be used to transform the stream's value. In the case of a non-stream object,
   returns the result of the function.
  
   The value to transform would typically be available to the function you pass
   to `chain()` via scope. For example:
  
   ```javascript
       var source = ...;  // stream returning a number
                              // or a numeric (non-stream) object
       var result = chain(source, function() {
         var currentValue = read(source);
         return currentValue + 1;
       });
   ```
  
   In the example, result is a stream if source is a stream, or a number of
   source was numeric.

  /**
    Strongly hint runtimes to intern the provided string.
  
    When do I need to use this function?
  
    For the most part, never. Pre-mature optimization is bad, and often the
    runtime does exactly what you need it to, and more often the trade-off isn't
    worth it.
  
    Why?
  
    Runtimes store strings in at least 2 different representations:
    Ropes and Symbols (interned strings). The Rope provides a memory efficient
    data-structure for strings created from concatenation or some other string
    manipulation like splitting.
  
    Unfortunately checking equality of different ropes can be quite costly as
    runtimes must resort to clever string comparison algorithms. These
    algorithms typically cost in proportion to the length of the string.
    Luckily, this is where the Symbols (interned strings) shine. As Symbols are
    unique by their string content, equality checks can be done by pointer
    comparison.
  
    How do I know if my string is a rope or symbol?
  
    Typically (warning general sweeping statement, but truthy in runtimes at
    present) static strings created as part of the JS source are interned.
    Strings often used for comparisons can be interned at runtime if some
    criteria are met.  One of these criteria can be the size of the entire rope.
    For example, in chrome 38 a rope longer then 12 characters will not
    intern, nor will segments of that rope.

    In order to store defaults for a class, a prototype may need to create
    a default meta object, which will be inherited by any objects instantiated
    from the class's constructor.
  
    However, the properties of that meta object are only shallow-cloned,
    so if a property is a hash (like the event system's `listeners` hash),
    it will by default be shared across all instances of that class.
  
    This method allows extensions to deeply clone a series of nested hashes or
    other complex objects. For instance, the event system might pass
    `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
    walk down the keys provided.
  
    For each key, if the key does not exist, it is created. If it already
    exists and it was inherited from its constructor, the constructor's
    key is cloned.
  
    You can also pass false for `writable`, which will simply return
    undefined if `prepareMetaPath` discovers any part of the path that
    shared or undefined.

  /**
    HTMLBars delegates the runtime behavior of a template to
    hooks provided by the host environment. These hooks explain
    the lexical environment of a Handlebars template, the internal
    representation of references, and the interaction between an
    HTMLBars template and the DOM it is managing.
  
    While HTMLBars host hooks have access to all of this internal
    machinery, templates and helpers have access to the abstraction
    provided by the host hooks.
  
    ## The Lexical Environment
  
    The default lexical environment of an HTMLBars template includes:
  
    * Any local variables, provided by *block arguments*
    * The current value of `self`
  
    ## Simple Nesting
  
    Let's look at a simple template with a nested block:
  
    ```hbs
    <h1>{{title}}</h1>
  
    {{#if author}}
      <p class="byline">{{author}}</p>
    {{/if}}
    ```
  
    In this case, the lexical environment at the top-level of the
    template does not change inside of the `if` block. This is
    achieved via an implementation of `if` that looks like this:
  
    ```js
    registerHelper('if', function(params) {
      if (!!params[0]) {
        return this.yield();
      }
    });
    ```
  
    A call to `this.yield` invokes the child template using the
    current lexical environment.
  
    ## Block Arguments
  
    It is possible for nested blocks to introduce new local
    variables:
  
    ```hbs
    {{#count-calls as |i|}}
    <h1>{{title}}</h1>
    <p>Called {{i}} times</p>
    {{/count}}
    ```
  
    In this example, the child block inherits its surrounding
    lexical environment, but augments it with a single new
    variable binding.
  
    The implementation of `count-calls` supplies the value of
    `i`, but does not otherwise alter the environment:
  
    ```js
    var count = 0;
    registerHelper('count-calls', function() {
      return this.yield([ ++count ]);
    });
    ```

    This host hook is a workhorse of the system. It is invoked
    whenever a block is encountered, and is responsible for
    resolving the helper to call, and then invoke it.
  
    The helper should be invoked with:
  
    - `{Array} params`: the parameters passed to the helper
      in the template.
    - `{Object} hash`: an object containing the keys and values passed
      in the hash position in the template.
  
    The values in `params` and `hash` will already be resolved
    through a previous call to the `get` host hook.
  
    The helper should be invoked with a `this` value that is
    an object with one field:
  
    `{Function} yield`: when invoked, this function executes the
    block with the current scope. It takes an optional array of
    block parameters. If block parameters are supplied, HTMLBars
    will invoke the `bindLocal` host hook to bind the supplied
    values to the block arguments provided by the template.
  
    In general, the default implementation of `block` should work
    for most host environments. It delegates to other host hooks
    where appropriate, and properly invokes the helper with the
    appropriate arguments.
