addArrayObserver (target, opts) Ember.Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:240

target: Object; The observer object.
opts: Hash; Optional hash of configuration options including `willChange` and `didChange` option.
returns: Ember.Array; receiver

Adds an array observer to the receiving array. The array observer object normally must implement two methods:

arrayWillChange(observedObj, start, removeCount, addCount) - This method will be called just before the array is modified.
arrayDidChange(observedObj, start, removeCount, addCount) - This method will be called just after the array is modified.

Both callbacks will be passed the observed object, starting index of the change as well a a count of the items to be removed and added. You can use these callbacks to optionally inspect the array during the change, clear caches, or do any other bookkeeping necessary.

In addition to passing a target, you can also include an options hash which you can use to override the method names that will be invoked on the target.

addEnumerableObserver (target, opts)

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:838

target: Object
opts: Hash
returns: this

Registers an enumerable observer. Must implement Ember.EnumerableObserver mixin.

addEnumerableObserver (target, opts)

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:838

target: Object
opts: Hash
returns: this

Registers an enumerable observer. Must implement Ember.EnumerableObserver mixin.

addObject (object) Object

Module: ember

Inherited from Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:51

object: Object; The object to add to the enumerable.
returns: Object; the passed object

Required. You must implement this method to apply this mixin.

Attempts to add the passed object to the receiver if the object is not already present in the collection. If the object is present, this method has no effect.

If the passed object is of a type not supported by the receiver, then this method should raise an exception.

addObjects (objects) Object

Module: ember

Inherited from Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:67

objects: Ember.Enumerable; the objects to add.
returns: Object; receiver

Adds each object in the passed enumerable to the receiver.

addObserver (key, target, method) Ember.Object

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:312

key: String; The key to observer
target: Object; The target object to invoke
method: String|Function; The method to invoke.
returns: Ember.Object; self

Adds an observer on a property.

This is the core method used to register an observer for a property.

Once you call this method, any time the key's value is set, your observer will be notified. Note that the observers are triggered any time the value is set, regardless of whether it has actually changed. Your observer should be prepared to handle that.

You can also pass an optional context parameter to this method. The context will be passed to your observer method whenever it is triggered. Note that if you add the same target/method pair on a key multiple times with different context parameters, your observer will only be called once with the last context you passed.

Observer Methods

Observer methods you pass should generally have the following signature if you do not pass a context parameter:

        
              fooDidChange: function(sender, key, value, rev) { };

The sender is the object that changed. The key is the property that changes. The value property is currently reserved and unused. The rev is the last property revision of the object when it changed, which you can use to detect if the key value has really changed or not.

If you pass a context parameter, the context will be passed before the revision like so:

        
              fooDidChange: function(sender, key, value, context, rev) { };

Usually you will not need the value, context or revision parameters at the end. In this case, it is common to write observer methods that take only a sender and key value as parameters or, if you aren't interested in any of these values, to write an observer that has no parameters at all.

any (callback, target) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:578

callback: Function; The callback to execute
target: Object; The target object to use
returns: Boolean; `true` if the passed function returns `true` for any item

Returns true if the passed function returns true for any item in the enumeration. This corresponds with the some() method in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

It should return the true to include the item in the results, false otherwise.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

Usage Example:

        
              if (people.any(isManager)) { Paychecks.addBiggerBonus(); }

any (callback, target) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:578

Returns true if the passed function returns true for any item in the enumeration. This corresponds with the some() method in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

It should return the true to include the item in the results, false otherwise.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

Usage Example:

        
              if (people.any(isManager)) { Paychecks.addBiggerBonus(); }

anyBy (key, value) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:653

key: String; the property to test
value: String; optional value to test against.
returns: Boolean; `true` if the passed function returns `true` for any item

Returns true if the passed property resolves to true for any item in the enumerable. This method is often simpler/faster than using a callback.

anyBy (key, value) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:653

key: String; the property to test
value: String; optional value to test against.
returns: Boolean; `true` if the passed function returns `true` for any item

Returns true if the passed property resolves to true for any item in the enumerable. This method is often simpler/faster than using a callback.

arrayContentDidChange (startIdx, removeAmt, addAmt) Ember.Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:353

startIdx: Number; The starting index in the array that did change.
removeAmt: Number; The number of items that were removed. If you pass `null` assumes 0
addAmt: Number; The number of items that were added. If you pass `null` assumes 0.
returns: Ember.Array; receiver

If you are implementing an object that supports Ember.Array, call this method just after the array content changes to notify any observers and invalidate any related properties. Pass the starting index of the change as well as a delta of the amounts to change.

arrayContentWillChange (startIdx, removeAmt, addAmt) Ember.Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:309

startIdx: Number; The starting index in the array that will change.
removeAmt: Number; The number of items that will be removed. If you pass `null` assumes 0
addAmt: Number; The number of items that will be added. If you pass `null` assumes 0.
returns: Ember.Array; receiver

If you are implementing an object that supports Ember.Array, call this method just before the array content changes to notify any observers and invalidate any related properties. Pass the starting index of the change as well as a delta of the amounts to change.

beginPropertyChanges Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:211

returns: Ember.Observable

Begins a grouping of property changes.

You can use this method to group property changes so that notifications will not be sent until the changes are finished. If you plan to make a large number of changes to an object at one time, you should call this method at the beginning of the changes to begin deferring change notifications. When you are done making changes, call endPropertyChanges() to deliver the deferred change notifications and end deferring.

cacheFor (keyName) Object

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:490

keyName: String
returns: Object; The cached value of the computed property, if any

Returns the cached value of a computed property, if it exists. This allows you to inspect the value of a computed property without accidentally invoking it if it is intended to be generated lazily.

clear Ember.Array

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:55

returns: Ember.Array; An empty Array.

Remove all elements from self. This is useful if you want to reuse an existing array without having to recreate it.

        
              var colors = ["red", "green", "blue"];
color.length();   //  3
colors.clear();   //  []
colors.length();  //  0

compact Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:760

returns: Array; the array without null and undefined elements.

Returns a copy of the array with all null and undefined elements removed.

        
              var arr = ["a", null, "c", undefined];
arr.compact();  // ["a", "c"]

compact Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:760

returns: Array; the array without null and undefined elements.

Returns a copy of the array with all null and undefined elements removed.

        
              var arr = ["a", null, "c", undefined];
arr.compact();  // ["a", "c"]

contains (obj) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:168

obj: Object; The object to search for.
returns: Boolean; `true` if object is found in enumerable.

Returns true if the passed object can be found in the receiver. The default version will iterate through the enumerable until the object is found. You may want to override this with a more efficient version.

        
              var arr = ["a", "b", "c"];
arr.contains("a"); // true
arr.contains("z"); // false

contains (obj) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:168

obj: Object; The object to search for.
returns: Boolean; `true` if object is found in enumerable.

Returns true if the passed object can be found in the receiver. The default version will iterate through the enumerable until the object is found. You may want to override this with a more efficient version.

        
              var arr = ["a", "b", "c"];
arr.contains("a"); // true
arr.contains("z"); // false

create (arguments)

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:435

arguments

Creates an instance of a class. Accepts either no arguments, or an object containing values to initialize the newly instantiated object with.

        
              App.Person = Ember.Object.extend({
  helloWorld: function() {
    alert("Hi, my name is " + this.get('name'));
  }
});

var tom = App.Person.create({
  name: 'Tom Dale'
});

tom.helloWorld(); // alerts "Hi, my name is Tom Dale".

create will call the init function if defined during Ember.AnyObject.extend

If no arguments are passed to create, it will not set values to the new instance during initialization:

        
              var noName = App.Person.create();
noName.helloWorld(); // alerts undefined

NOTE: For performance reasons, you cannot declare methods or computed properties during create. You should instead declare methods and computed properties when using extend or use the createWithMixins shorthand.

createWithMixins (arguments)

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:421

arguments

Equivalent to doing extend(arguments).create(). If possible use the normal create method instead.

decrementProperty (keyName, decrement) Number

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:453

keyName: String; The name of the property to decrement
decrement: Number; The amount to decrement by. Defaults to 1
returns: Number; The new property value

Set the value of a property to the current value minus some amount.

        
              player.decrementProperty('lives');
orc.decrementProperty('health', 5);

destroy Ember.Object

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:289

returns: Ember.Object; receiver

Destroys an object by setting the isDestroyed flag and removing its metadata, which effectively destroys observers and bindings.

If you try to set a property on a destroyed object, an exception will be raised.

Note that destruction is scheduled for the end of the run loop and does not happen immediately. It will set an isDestroying flag immediately.

eachComputedProperty (callback, binding)

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:590

callback: Function
binding: Object

Iterate over each computed property for the class, passing its name and any associated metadata (see metaForProperty) to the callback.

endPropertyChanges Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:230

returns: Ember.Observable

Ends a grouping of property changes.

You can use this method to group property changes so that notifications will not be sent until the changes are finished. If you plan to make a large number of changes to an object at one time, you should call beginPropertyChanges() at the beginning of the changes to defer change notifications. When you are done making changes, call this method to deliver the deferred change notifications and end deferring.

enumerableContentDidChange (start, removing, adding)

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:927

start: Number; optional start offset for the content change. For unordered enumerables, you should always pass -1.
removing: Ember.Enumerable|Number; An enumerable of the objects to be removed or the number of items to be removed.
adding: Ember.Enumerable|Number; An enumerable of the objects to be added or the number of items to be added.

Invoke this method when the contents of your enumerable has changed. This will notify any observers watching for content changes. If your are implementing an ordered enumerable (such as an array), also pass the start and end values where the content changed so that it can be used to notify range observers.

every (callback, target) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:515

callback: Function; The callback to execute
target: Object; The target object to use

              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

It should return the true or false.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:316

callback: Function; The callback to execute
target: Object; The target object to use
returns: Array; A filtered array.

Returns an array with all of the items in the enumeration that the passed function returns true for. This method corresponds to filter() defined in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.

callback: Function; The callback to execute
target: Object; The target object to use
returns: Object; Found item or `undefined`.

Returns the first item in the array for which the callback returns true. This method works similar to the filter() method defined in JavaScript 1.6 except that it will stop working on the array once a match is found.

key: String; the property to test
value: String; optional value to test against.
returns: Object; found item or `undefined`

Returns the first item with a property matching the passed value. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to true.

This method works much like the more generic find() method.

forEach (callback, target) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:187

callback: Function; The callback to execute
target: Object; The target object to use
returns: Object; receiver

Iterates through the enumerable, calling the passed function on each item. This method corresponds to the forEach() method defined in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

forEach (callback, target) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:187

callback: Function; The callback to execute
target: Object; The target object to use
returns: Object; receiver

Iterates through the enumerable, calling the passed function on each item. This method corresponds to the forEach() method defined in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

get (keyName) Object

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:78

keyName: String; The property to retrieve
returns: Object; The property value or undefined.

Retrieves the value of a property from the object.

This method is usually similar to using object[keyName] or object.keyName, however it supports both computed properties and the unknownProperty handler.

Because get unifies the syntax for accessing all these kinds of properties, it can make many refactorings easier, such as replacing a simple property with a computed property, or vice versa.

Computed Properties

Computed properties are methods defined with the property modifier declared at the end, such as:

        
              fullName: function() {
  return this.getEach('firstName', 'lastName').compact().join(' ');
}.property('firstName', 'lastName')

When you call get on a computed property, the function will be called and the return value will be returned instead of the function itself.

Unknown Properties

Likewise, if you try to call get on a property whose value is undefined, the unknownProperty() method will be called on the object. If this method returns any value other than undefined, it will be returned instead. This allows you to implement "virtual" properties that are not defined upfront.

getEach (key) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:228

key: String; name of the property
returns: Array; The mapped array.

Alias for mapBy

getProperties (list) Hash

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:120

list: String...|Array; of keys to get
returns: Hash

To get multiple properties at once, call getProperties with a list of strings or an array:

        
              record.getProperties('firstName', 'lastName', 'zipCode');  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }

is equivalent to:

        
              record.getProperties(['firstName', 'lastName', 'zipCode']);  // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }

getWithDefault (keyName, defaultValue) Object

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:416

defaultValue: Object; The value to return if the property value is undefined
returns: Object; The property value or the defaultValue.

Retrieves the value of a property, or a default value in the case that the property returns undefined.

        
              person.getWithDefault('lastName', 'Doe');

hasObserverFor (key) Boolean

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:379

key: String; Key to check
returns: Boolean

Returns true if the object currently has observers registered for a particular key. You can use this method to potentially defer performing an expensive action until someone begins observing a particular property on the object.

incrementProperty (keyName, increment) Number

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:433

keyName: String; The name of the property to increment
increment: Number; The amount to increment by. Defaults to 1
returns: Number; The new property value

Set the value of a property to the current value plus some amount.

        
              person.incrementProperty('age');
team.incrementProperty('score', 2);

indexOf (object, startAt) Number

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:170

object: Object; the item to search for
startAt: Number; optional starting location to search, default 0
returns: Number; index or -1 if not found

Returns the index of the given object's first occurrence. If no startAt argument is given, the starting location to search is 0. If it's negative, will count backward from the end of the array. Returns -1 if no match is found.

        
              var arr = ["a", "b", "c", "d", "a"];
arr.indexOf("a");       //  0
arr.indexOf("z");       // -1
arr.indexOf("a", 2);    //  4
arr.indexOf("a", -1);   //  4
arr.indexOf("b", 3);    // -1
arr.indexOf("a", 100);  // -1

init

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:171

An overridable method called when objects are instantiated. By default, does nothing unless it is overridden during class definition.

Example:

        
              App.Person = Ember.Object.extend({
  init: function() {
    this._super();
    alert('Name is ' + this.get('name'));
  }
});

var steve = App.Person.create({
  name: "Steve"
});

// alerts 'Name is Steve'.

NOTE: If you do override init for a framework class like Ember.View or Ember.ArrayController, be sure to call this._super() in your init declaration! If you don't, Ember may not have an opportunity to do important setup work, and you'll see strange behavior in your application.

insertAt (idx, object)

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:76

idx: Number; index of insert the object at.
object: Object; object to insert
returns: this

This will use the primitive replace() method to insert an object at the specified index.

        
              var colors = ["red", "green", "blue"];
colors.insertAt(2, "yellow");  // ["red", "green", "yellow", "blue"]
colors.insertAt(5, "orange");  // Error: Index out of range

invoke (methodName, args) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:723

methodName: String; the name of the method
args: Object...; optional arguments to pass as well.
returns: Array; return values from calling invoke.

Invokes the named method on every object in the receiver that implements it. This method corresponds to the implementation in Prototype 1.6.

invoke (methodName, args) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:723

methodName: String; the name of the method
args: Object...; optional arguments to pass as well.
returns: Array; return values from calling invoke.

Invokes the named method on every object in the receiver that implements it. This method corresponds to the implementation in Prototype 1.6.

lastIndexOf (object, startAt) Number

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:203

object: Object; the item to search for
startAt: Number; optional starting location to search, default 0
returns: Number; index or -1 if not found

Returns the index of the given object's last occurrence. If no startAt argument is given, the search starts from the last position. If it's negative, will count backward from the end of the array. Returns -1 if no match is found.

        
              var arr = ["a", "b", "c", "d", "a"];
arr.lastIndexOf("a");       //  4
arr.lastIndexOf("z");       // -1
arr.lastIndexOf("a", 2);    //  0
arr.lastIndexOf("a", -1);   //  4
arr.lastIndexOf("b", 3);    //  1
arr.lastIndexOf("a", 100);  //  4

lookupItemController (object) String

Module: ember

Defined in packages/ember-runtime/lib/controllers/array_controller.js:113

object: Object
returns: String

Return the name of the controller to wrap items, or null if items should be returned directly. The default implementation simply returns the itemController property, but subclasses can override this method to return different controllers for different objects.

For example:

        
              App.MyArrayController = Ember.ArrayController.extend({
  lookupItemController: function( object ) {
    if (object.get('isSpecial')) {
      return "special"; // use App.SpecialController
    } else {
      return "regular"; // use App.RegularController
    }
  }
});

map (callback, target) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:256

callback: Function; The callback to execute
target: Object; The target object to use
returns: Array; The mapped array.

Maps all of the items in the enumeration to another value, returning a new array. This method corresponds to map() defined in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

It should return the mapped value.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

map (callback, target) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:256

callback: Function; The callback to execute
target: Object; The target object to use
returns: Array; The mapped array.

Maps all of the items in the enumeration to another value, returning a new array. This method corresponds to map() defined in JavaScript 1.6.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

It should return the mapped value.

Note that in addition to a callback, you can also pass an optional target object that will be set as this on the context. This is a good way to give your iterator function access to the current object.

mapBy (key) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:290

key: String; name of the property
returns: Array; The mapped array.

Similar to map, this specialized function returns the value of the named property on all items in the enumeration.

mapBy (key) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:290

key: String; name of the property
returns: Array; The mapped array.

Similar to map, this specialized function returns the value of the named property on all items in the enumeration.

metaForProperty (key)

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:556

key: String; property name

In some cases, you may want to annotate computed properties with additional metadata about how they function or what values they operate on. For example, computed property functions may close over variables that are then no longer available for introspection.

You can pass a hash of these values to a computed property like this:

        
              person: function() {
  var personId = this.get('personId');
  return App.Person.create({ id: personId });
}.property().meta({ type: App.Person })

Once you've done this, you can retrieve the values saved to the computed property from your class like this:

        
              MyClass.metaForProperty('person');

This will return the original hash that was passed to meta().

nextObject (index, previousObject, context) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:74

index: Number; the current index of the iteration
previousObject: Object; the value returned by the last call to `nextObject`.
context: Object; a context object you can use to maintain state.
returns: Object; the next object in the iteration or undefined

Implement this method to make your class enumerable.

This method will be call repeatedly during enumeration. The index value will always begin with 0 and increment monotonically. You don't have to rely on the index value to determine what object to return, but you should always check the value and start from the beginning when you see the requested index is 0.

The previousObject is the object that was returned from the last call to nextObject for the current iteration. This is a useful way to manage iteration if you are tracing a linked list, for example.

Finally the context parameter will always contain a hash you can use as a "scratchpad" to maintain any other state you need in order to iterate properly. The context object is reused and is not reset between iterations so make sure you setup the context with a fresh state whenever the index parameter is 0.

Generally iterators will continue to call nextObject until the index reaches the your current length-1. If you run out of data before this time for some reason, you should simply return undefined.

The default implementation of this method simply looks up the index. This works great on any Array-like objects.

nextObject (index, previousObject, context) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:74

index: Number; the current index of the iteration
previousObject: Object; the value returned by the last call to `nextObject`.
context: Object; a context object you can use to maintain state.
returns: Object; the next object in the iteration or undefined

notifyPropertyChange (keyName) Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:294

keyName: String; The property key to be notified about.
returns: Ember.Observable

Convenience method to call propertyWillChange and propertyDidChange in succession.

objectAt (idx) *

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:59

idx: Number; The index of the item to return.
returns: *; item at index or undefined

Returns the object at the given index. If the given index is negative or is greater or equal than the array length, returns undefined.

This is one of the primitives you must implement to support Ember.Array. If your object supports retrieving the value of an array item using get() (i.e. myArray.get(0)), then you do not need to implement this method yourself.

        
              var arr = ['a', 'b', 'c', 'd'];
arr.objectAt(0);   // "a"
arr.objectAt(3);   // "d"
arr.objectAt(-1);  // undefined
arr.objectAt(4);   // undefined
arr.objectAt(5);   // undefined

objectAtContent (idx) Object

Module: ember

Inherited from Ember.ArrayProxy packages/ember-runtime/lib/system/array_proxy.js:72

idx: Number; The index to retrieve.
returns: Object; the value or undefined if none found

Should actually retrieve the object at the specified index from the content. You can override this method in subclasses to transform the content item to something new.

This method will only be called if content is non-null.

objectsAt (indexes) Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:86

indexes: Array; An array of indexes of items to return.
returns: Array

This returns the objects at the specified indexes, using objectAt.

        
              var arr = ['a', 'b', 'c', 'd'];
arr.objectsAt([0, 1, 2]);  // ["a", "b", "c"]
arr.objectsAt([2, 3, 4]);  // ["c", "d", undefined]

popObject

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:172

returns: object

Pop object from array or nil if none are left. Works just like pop() but it is KVO-compliant.

        
              var colors = ["red", "green", "blue"];
colors.popObject();   // "blue"
console.log(colors);  // ["red", "green"]

propertyDidChange (keyName) Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:271

keyName: String; The property key that has just changed.
returns: Ember.Observable

Notify the observer system that a property has just changed.

Sometimes you need to change a value directly or indirectly without actually calling get() or set() on it. In this case, you can use this method and propertyWillChange() instead. Calling these two methods together will notify all observers that the property has potentially changed value.

Note that you must always call propertyWillChange and propertyDidChange as a pair. If you do not, it may get the property change groups out of order and cause notifications to be delivered more often than you would like.

propertyWillChange (keyName) Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:248

keyName: String; The property key that is about to change.
returns: Ember.Observable

Notify the observer system that a property is about to change.

Sometimes you need to change a value directly or indirectly without actually calling get() or set() on it. In this case, you can use this method and propertyDidChange() instead. Calling these two methods together will notify all observers that the property has potentially changed value.

Note that you must always call propertyWillChange and propertyDidChange as a pair. If you do not, it may get the property change groups out of order and cause notifications to be delivered more often than you would like.

pushObject (obj) *

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:131

obj: *; object to push
returns: *; the same obj passed as param

Push the object onto the end of the array. Works just like push() but it is KVO-compliant.

        
              var colors = ["red", "green", "blue"];
colors.pushObject("black");               // ["red", "green", "blue", "black"]
colors.pushObject(["yellow", "orange"]);  // ["red", "green", "blue", "black", ["yellow", "orange"]]

pushObjects (objects) Ember.Array

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:150

objects: Ember.Enumerable; the objects to add
returns: Ember.Array; receiver

Add the objects in the passed numerable to the end of the array. Defers notifying observers of the change until all objects are added.

        
              var colors = ["red", "green", "blue"];
colors.pushObjects(["black"]);               // ["red", "green", "blue", "black"]
colors.pushObjects(["yellow", "orange"]);  // ["red", "green", "blue", "black", "yellow", "orange"]

reduce (callback, initialValue, reducerProperty) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:678

callback: Function; The callback to execute
initialValue: Object; Initial value for the reduce
reducerProperty: String; internal use only.
returns: Object; The reduced value.

This will combine the values of the enumerator into a single value. It is a useful way to collect a summary value from an enumeration. This corresponds to the reduce() method defined in JavaScript 1.8.

The callback method you provide should have the following signature (all parameters are optional):

        
              function(previousValue, item, index, enumerable);

previousValue is the value returned by the last call to the iterator.
item is the current item in the iteration.
index is the current index in the iteration.
enumerable is the enumerable object itself.

Return the new cumulative value.

In addition to the callback you can also pass an initialValue. An error will be raised if you do not pass an initial value and the enumerator is empty.

Note that unlike the other methods, this method does not allow you to pass a target object to set as this for the callback. It's part of the spec. Sorry.

reject (callback, target) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:352

callback: Function; The callback to execute
target: Object; The target object to use
returns: Array; A rejected array.

Returns an array with all of the items in the enumeration where the passed function returns false for. This method is the inverse of filter().

The callback method you provide should have the following signature (all parameters are optional):

        
                function(item, index, enumerable);

item is the current item in the iteration.
index is the current index in the iteration
enumerable is the enumerable object itself.

It should return the a falsey value to include the item in the results.

Note that in addition to a callback, you can also pass an optional target object that will be set as "this" on the context. This is a good way to give your iterator function access to the current object.

removeArrayObserver (target, opts) Ember.Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:276

target: Object; The object observing the array.
opts: Hash; Optional hash of configuration options including `willChange` and `didChange` option.
returns: Ember.Array; receiver

start: Number; index, start of range
len: Number; length of passing range
returns: Object; receiver

Remove an object at the specified index using the replace() primitive method. You can pass either a single index, or a start and a length.

If you pass a start and length that is beyond the length this method will throw an OUT_OF_RANGE_EXCEPTION

        
              var colors = ["red", "green", "blue", "yellow", "orange"];
colors.removeAt(0);     // ["green", "blue", "yellow", "orange"]

replace (idx, amt, objects)

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:38

idx: Number; Starting index in the array to replace. If idx >= length, then append to the end of the array.
amt: Number; Number of elements that should be removed from the array, starting at *idx*.
objects: Array; An array of zero or more objects that should be inserted into the array at *idx*

Required. You must implement this method to apply this mixin.

This is one of the primitives you must implement to support Ember.Array. You should replace amt objects started at idx with the objects in the passed array. You should also call this.enumerableContentDidChange()

replaceContent (idx, amt, objects) Void

Module: ember

Inherited from Ember.ArrayProxy packages/ember-runtime/lib/system/array_proxy.js:87

idx: Number; The starting index
amt: Number; The number of items to remove from the content.
objects: Array; Optional array of objects to insert or null if no objects.
returns: Void

Should actually replace the specified objects on the content array. You can override this method in subclasses to transform the content item into something new.

This method will only be called if content is non-null.

replaceRoute (name, models)

Module: ember

Inherited from Ember.ControllerMixin packages/ember-routing/lib/ext/controller.js:48

name: String; the name of the route
models: ...Object; the

Alernative to transitionToRoute. Transition the application into another route. The route may be either a single route or route path:

        
                aController.replaceRoute('blogPosts');
  aController.replaceRoute('blogPosts.recentEntries');

Optionally supply a model for the route in question. The model will be serialized into the URL using the serialize hook of the route:

        
                aController.replaceRoute('blogPost', aPost);

reverseObjects Ember.Array

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:252

Reverse objects in the array. Works just like reverse() but it is KVO-compliant.

set (keyName, value) Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:142

keyName: String; The property to set
value: Object; The value to set or `null`.
returns: Ember.Observable

Sets the provided key or path to the value.

This method is generally very similar to calling object[key] = value or object.key = value, except that it provides support for computed properties, the setUnknownProperty() method and property observers.

Computed Properties

If you try to set a value on a key that has a computed property handler defined (see the get() method for an example), then set() will call that method, passing both the value and key instead of simply changing the value itself. This is useful for those times when you need to implement a property that is composed of one or more member properties.

Unknown Properties

If you try to set a value on a key that is undefined in the target object, then the setUnknownProperty() handler will be called instead. This gives you an opportunity to implement complex "virtual" properties that are not predefined on the object. If setUnknownProperty() returns undefined, then set() will simply set the value on the object.

Property Observers

In addition to changing the property, set() will also register a property change with the object. Unless you have placed this call inside of a beginPropertyChanges() and endPropertyChanges(), any "local" observers (i.e. observer methods declared on the same object), will be called immediately. Any "remote" observers (i.e. observer methods declared on another object) will be placed in a queue and called at a later time in a coalesced manner.

Chaining

In addition to property changes, set() returns the value of the object itself so you can do chaining like this:

        
              record.set('firstName', 'Charles').set('lastName', 'Jolley');

setEach (key, value) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:239

key: String; The key to set
value: Object; The object to set
returns: Object; receiver

Sets the value on the named property for each member. This is more efficient than using other methods defined on this helper. If the object implements Ember.Observable, the value will be changed to set(), otherwise it will be set directly. null objects are skipped.

setEach (key, value) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:239

key: String; The key to set
value: Object; The object to set
returns: Object; receiver

Sets the value on the named property for each member. This is more efficient than using other methods defined on this helper. If the object implements Ember.Observable, the value will be changed to set(), otherwise it will be set directly. null objects are skipped.

setObjects (objects) Ember.Array

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:267

objects: Ember.Array; array whose content will be used for replacing the content of the receiver
returns: Ember.Array; receiver with the new content

Replace all the the receiver's content with content of the argument. If argument is an empty array receiver will be cleared.

        
              var colors = ["red", "green", "blue"];
colors.setObjects(["black", "white"]);  // ["black", "white"]
colors.setObjects([]);                  // []

setProperties (hash) Ember.Observable

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:195

hash: Hash; the hash of keys and values to set
returns: Ember.Observable

To set multiple properties at once, call setProperties with a Hash:

        
              record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });

shiftObject

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:194

returns: object

Shift an object from start of array or nil if none are left. Works just like shift() but it is KVO-compliant.

        
              var colors = ["red", "green", "blue"];
colors.shiftObject();  // "red"
console.log(colors);   // ["green", "blue"]

slice (beginIndex, endIndex) Array

Module: ember

Inherited from Ember.Array packages/ember-runtime/lib/mixins/array.js:138

beginIndex: Integer; (Optional) index to begin slicing from.
endIndex: Integer; (Optional) index to end the slice at.
returns: Array; New array with specified slice

Returns a new array that is a slice of the receiver. This implementation uses the observable array methods to retrieve the objects for the new slice.

        
              var arr = ['red', 'green', 'blue'];
arr.slice(0);       // ['red', 'green', 'blue']
arr.slice(0, 2);    // ['red', 'green']
arr.slice(1, 100);  // ['green', 'blue']

toArray Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:747

returns: Array; the enumerable as an array.

Simply converts the enumerable into a genuine array. The order is not guaranteed. Corresponds to the method implemented by Prototype.

toString String

Module: ember

Inherited from Ember.CoreObject packages/ember-runtime/lib/system/core_object.js:338

returns: String; string representation

Returns a string representation which attempts to provide more information than Javascript's toString typically does, in a generic way for all Ember objects.

        
              App.Person = Em.Object.extend()
person = App.Person.create()
person.toString() //=> "<App.Person:ember1024>"

If the object's class is not defined on an Ember namespace, it will indicate it is a subclass of the registered superclass:

        
              Student = App.Person.extend()
student = Student.create()
student.toString() //=> "<(subclass of App.Person):ember1025>"

If the method toStringExtension is defined, its return value will be included in the output.

        
              App.Teacher = App.Person.extend({
  toStringExtension: function() {
    return this.get('fullName');
  }
});
teacher = App.Teacher.create()
teacher.toString(); //=> "<App.Teacher:ember1026:Tom Dale>"

toggleProperty (keyName) Object

Module: ember

Inherited from Ember.Observable packages/ember-runtime/lib/mixins/observable.js:473

keyName: String; The name of the property to toggle
returns: Object; The new property value

Set the value of a boolean property to the opposite of it's current value.

        
              starship.toggleProperty('warpDriveEngaged');

transitionToRoute (name, models)

Module: ember

Inherited from Ember.ControllerMixin packages/ember-routing/lib/ext/controller.js:9

name: String; the name of the route
models: ...Object; the

Transition the application into another route. The route may be either a single route or route path:

        
                aController.transitionToRoute('blogPosts');
  aController.transitionToRoute('blogPosts.recentEntries');

Optionally supply a model for the route in question. The model will be serialized into the URL using the serialize hook of the route:

        
                aController.transitionToRoute('blogPost', aPost);

uniq Ember.Enumerable

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:798

returns: Ember.Enumerable

Returns a new enumerable that contains only unique values. The default implementation returns an array regardless of the receiver type.

        
              var arr = ["a", "a", "b", "b"];
arr.uniq();  // ["a", "b"]

uniq Ember.Enumerable

Module: ember

              var arr = ["a", "a", "b", "b"];
arr.uniq();  // ["a", "b"]

unshiftObject (obj) *

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:214

obj: *; object to unshift
returns: *; the same obj passed as param

Unshift an object to start of array. Works just like unshift() but it is KVO-compliant.

        
              var colors = ["red", "green", "blue"];
colors.unshiftObject("yellow");             // ["yellow", "red", "green", "blue"]
colors.unshiftObject(["black", "white"]);   // [["black", "white"], "yellow", "red", "green", "blue"]

unshiftObjects (objects) Ember.Array

Module: ember

Inherited from Ember.MutableArray packages/ember-runtime/lib/mixins/mutable_array.js:233

objects: Ember.Enumerable; the objects to add
returns: Ember.Array; receiver

Adds the named objects to the beginning of the array. Defers notifying observers until all objects have been added.

        
              var colors = ["red", "green", "blue"];
colors.unshiftObjects(["black", "white"]);   // ["black", "white", "red", "green", "blue"]
colors.unshiftObjects("yellow");             // Type Error: 'undefined' is not a function
