Ember.MutableArray - 1.0 - Ember API Documentation

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.

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.

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(); }

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.

clear Ember.Array

Module: ember

Defined in 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"]

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

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.

enumerableContentWillChange (removing, adding)

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:891

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 just before the contents of your enumerable will change. You can either omit the parameters completely or pass the objects to be removed or added if available or just a count.

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
returns: Boolean

Returns true if the passed function returns true for every item in the enumeration. This corresponds with the every() 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 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.

Example Usage:

        
              if (people.every(isEngineer)) { Paychecks.addBigBonus(); }

everyBy (key, value) Boolean

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:553

key: String; the property to test
value: String; optional value to test against.
returns: Boolean

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

filter (callback, target) Array

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.
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.

filterBy (key, value) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:382

key: String; the property to test
value: String; optional value to test against.
returns: Array; filtered array

Returns an array with just the items with the matched property. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to true.

find (callback, target) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:440

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.

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.

findBy (key, value) Object

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:484

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.

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

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

insertAt (idx, object)

Module: ember

Defined in 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.

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

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.

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.

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

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

Defined in 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"]

pushObject (obj) *

Module: ember

Defined in 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

Defined in 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.

rejectBy (key, value) Array

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:409

key: String; the property to test
value: String; optional value to test against.
returns: Array; rejected array

Returns an array with the items that do not have truthy values for key. You can pass an optional second argument with the target value. Otherwise this will match any property that evaluates to false.

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

Removes an array observer from the object if the observer is current registered. Calling this method multiple times with the same object will have no effect.

removeAt (start, len) Object

Module: ember

Defined in packages/ember-runtime/lib/mixins/mutable_array.js:97

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"]
colors.removeAt(2, 2);  // ["green", "blue"]
colors.removeAt(4, 2);  // Error: Index out of range

removeEnumerableObserver (target, opts)

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:859

target: Object
opts: Hash
returns: this

Removes a registered enumerable observer.

removeObject (object) Object

Module: ember

Inherited from Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:81

object: Object; The object to remove from the enumerable.
returns: Object; the passed object

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

Attempts to remove the passed object from the receiver collection if the object is present in the collection. If the object is not 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.

removeObjects (objects) Object

Module: ember

Inherited from Ember.MutableEnumerable packages/ember-runtime/lib/mixins/mutable_enumerable.js:98

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

Removes each object in the passed enumerable from the receiver.

replace (idx, amt, objects)

Module: ember

Defined in 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()

reverseObjects Ember.Array

Module: ember

Defined in packages/ember-runtime/lib/mixins/mutable_array.js:252

returns: Ember.Array; receiver

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

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

Defined in 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([]);                  // []

shiftObject

Module: ember

Defined in 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.

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"]

unshiftObject (obj) *

Module: ember

Defined in 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

Defined in 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

without (value) Ember.Enumerable

Module: ember

Inherited from Ember.Enumerable packages/ember-runtime/lib/mixins/enumerable.js:775

value: Object
returns: Ember.Enumerable

Returns a new enumerable that excludes the passed value. The default implementation returns an array regardless of the receiver type unless the receiver does not contain the value.

        
              var arr = ["a", "b", "a", "c"];
arr.without("a");  // ["b", "c"]
