/**
* Takes in an AST and outputs a list of actions to be consumed
* by a compiler. For example, the template
*
* foo{{bar}}<div>baz</div>
*
* produces the actions
*
* [['startProgram', [programNode, 0]],
* ['text', [textNode, 0, 3]],
* ['mustache', [mustacheNode, 1, 3]],
* ['openElement', [elementNode, 2, 3, 0]],
* ['text', [textNode, 0, 1]],
* ['closeElement', [elementNode, 2, 3],
* ['endProgram', [programNode]]]
*
* This visitor walks the AST depth first and backwards. As
* a result the bottom-most child template will appear at the
* top of the actions list whereas the root template will appear
* at the bottom of the list. For example,
*
* <div>{{#if}}foo{{else}}bar<b></b>{{/if}}</div>
*
* produces the actions
*
* [['startProgram', [programNode, 0]],
* ['text', [textNode, 0, 2, 0]],
* ['openElement', [elementNode, 1, 2, 0]],
* ['closeElement', [elementNode, 1, 2]],
* ['endProgram', [programNode]],
* ['startProgram', [programNode, 0]],
* ['text', [textNode, 0, 1]],
* ['endProgram', [programNode]],
* ['startProgram', [programNode, 2]],
* ['openElement', [elementNode, 0, 1, 1]],
* ['block', [blockNode, 0, 1]],
* ['closeElement', [elementNode, 0, 1]],
* ['endProgram', [programNode]]]
*
* The state of the traversal is maintained by a stack of frames.
* Whenever a node with children is entered (either a ProgramNode
* or an ElementNode) a frame is pushed onto the stack. The frame
* contains information about the state of the traversal of that
* node. For example,
*
* - index of the current child node being visited
* - the number of mustaches contained within its child nodes
* - the list of actions generated by its child nodes

Allows for runtime registration of handler functions that override the default deprecation behavior.
Deprecations are invoked by calls to [Ember.deprecate](https://emberjs.com/api/classes/Ember.html#method_deprecate).
The following example demonstrates its usage by registering a handler that throws an error if the
message contains the word "should", otherwise defers to the default handler.
```javascript
Ember.Debug.registerDeprecationHandler((message, options, next) => {
if (message.indexOf('should') !== -1) {
throw new Error(`Deprecation message with should: ${message}`);
} else {
// defer to whatever handler was registered before this one
next(message, options);
}

```
The handler function takes the following arguments:
<ul>
<li> <code>message</code> - The message received from the deprecation call.</li>
<li> <code>options</code> - An object passed in with the deprecation call containing additional information including:</li>
<ul>
<li> <code>id</code> - An id of the deprecation in the form of <code>package-name.specific-deprecation</code>.</li>
<li> <code>until</code> - The Ember version number the feature and deprecation will be removed in.</li>

/**
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('firstName', 'lastName', function() {
return this.firstName+' '+this.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.

/**
A computed property transforms an object literal with object's accessor function(s) 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 - `fullName` - by calling
`.Ember.computed()` with property dependencies (`firstName` and `lastName`) as leading arguments and getter accessor function. The `fullName` getter 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
let Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: Ember.computed('firstName', 'lastName', function() {
let firstName = this.get('firstName'),
lastName = this.get('lastName');
return firstName + ' ' + lastName;
})
});
let 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 by providing additional function (`set`) in hash argument.
If you try to set a computed property, it will try to invoke setter accessor function with the key and
value you want to set it to as arguments.
```javascript
let Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: Ember.computed('firstName', 'lastName', {
get(key) {
let firstName = this.get('firstName'),
lastName = this.get('lastName');
return firstName + ' ' + lastName;
},
set(key, value) {
let [firstName, lastName] = value.split(' ');
this.set('firstName', firstName);
this.set('lastName', lastName);
return value;
}
})
});
let person = Person.create();
person.set('fullName', 'Peter Wagenet');
person.get('firstName'); // 'Peter'
person.get('lastName'); // 'Wagenet'
```
You can overwrite computed property with normal property (no longer computed), that won't change if dependencies change, if you set computed property and it won't have setter accessor function defined.
You can also mark computed property as `.readOnly()` and block all attempts to set it.
```javascript
let Person = Ember.Object.extend({
// these will be supplied by `create`
firstName: null,
lastName: null,
fullName: Ember.computed('firstName', 'lastName', {
get(key) {
let firstName = this.get('firstName');
let lastName = this.get('lastName');
return firstName + ' ' + lastName;
}
}).readOnly()
});
let person = Person.create();
person.set('fullName', 'Peter Wagenet'); // Uncaught Error: Cannot set read-only property "fullName" on object: <(...):emberXXX>
```

/**
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()`.
If you pass a function as an argument, it will be used as a getter. A computed
property defined in this way might look like this:
```js
let Person = Ember.Object.extend({
init() {
this._super(...arguments);
this.firstName = 'Betty';
this.lastName = 'Jones';
},
fullName: Ember.computed('firstName', 'lastName', function() {
return `${this.get('firstName')} ${this.get('lastName')}`;
})
});
let client = Person.create();
client.get('fullName'); // 'Betty Jones'
client.set('lastName', 'Fuller');
client.get('fullName'); // 'Betty Fuller'
```
You can pass a hash with two functions, `get` and `set`, as an
argument to provide both a getter and setter:
```js
let Person = Ember.Object.extend({
init() {
this._super(...arguments);
this.firstName = 'Betty';
this.lastName = 'Jones';
},
fullName: Ember.computed('firstName', 'lastName', {
get(key) {
return `${this.get('firstName')} ${this.get('lastName')}`;
},
set(key, value) {
let [firstName, lastName] = value.split(/\s+/);
this.setProperties({ firstName, lastName });
return value;
}
})
});
let client = Person.create();
client.get('firstName'); // 'Betty'
client.set('fullName', 'Carroll Fuller');
client.get('firstName'); // 'Carroll'
```
The `set` function should accept two parameters, `key` and `value`. The value
returned from `set` will be the new value of the property.
_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
will have [prototype Extensions](https://emberjs.com/guides/configuring-ember/disabling-prototype-extensions/) enabled._
The alternative syntax, with prototype extensions, might look like:
```js
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
}.property('firstName', 'lastName')
```

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(name, timestamp, payload) {
},
after(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`.

/**
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.

/**
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
export default Ember.Component.extend({
didInsertElement() {
this._super(...arguments);
run.scheduleOnce('afterRender', this, 'processChildElements');
},
processChildElements() {
// ... do something with component's child component
// elements after they've finished rendering, which
// can't be done within this component'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`.

/**
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.

/**
The `Ember.Mixin` class allows you to create mixins, whose properties can be
added to other classes. For instance,
```javascript
const EditableMixin = Ember.Mixin.create({
edit() {
console.log('starting to edit');
this.set('isEditing', true);
},
isEditing: false
});
// Mix mixins into classes by passing them as the first arguments to
// `.extend.`
const Comment = Ember.Object.extend(EditableMixin, {
post: null
});
let comment = Comment.create({
post: somePost
});
comment.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
const FilterableMixin = Ember.Mixin.create({
filters: Ember.A()
});
// filters will be a separate array for every object implementing the mixin
const FilterableMixin = Ember.Mixin.create({
filters: Ember.computed(function() {
return Ember.A();
})
});
// filters will be created as a separate array during the object's initialization
const Filterable = Ember.Mixin.create({
init() {
this._super(...arguments);
this.set("filters", Ember.A());
}
});

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.
