ICollectionView
or IList
interfaces. Operations on a ArrayCollection instance modify the data source;
for example, if you use the removeItemAt()
method on an
ArrayCollection, you remove the item from the underlying Array.

ArrayCollection(source:Array = null)
Constructor. | ArrayCollection | ||
Adds a list of items to the current list, placing them at the end of
the list in the order they are passed. | ListCollectionView | ||
Adds a list of items to the current list, placing them at the position
index passed in to the function. | ListCollectionView | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | ListCollectionView | ||
Adds the specified item to the end of the list. | ListCollectionView | ||
Adds the item at the specified index. | ListCollectionView | ||
Returns whether the view contains the specified object. | ListCollectionView | ||
Creates a new IViewCursor that works with this view. | ListCollectionView | ||
Prevents changes to the collection itself and items within the
collection from being dispatched by the view. | ListCollectionView | ||
Dispatches an event into the event flow. | ListCollectionView | ||
Enables auto-updating. | ListCollectionView | ||
Gets the item at the specified index. | ListCollectionView | ||
Returns the index of the item if it is in the list such that
getItemAt(index) == item. | ListCollectionView | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | ListCollectionView | ||
Indicates whether an object has a specified property defined. | Object | ||
Called automatically by the MXML compiler when the ListCollectionView
is created using an MXML tag. | ListCollectionView | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
itemUpdated(item:Object, property:Object = null, oldValue:Object = null, newValue:Object = null):void
Notifies the view that an item has been updated. | ListCollectionView | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Applies the sort and filter to the view. | ListCollectionView | ||
Remove all items from the list. | ListCollectionView | ||
Removes a listener from the EventDispatcher object. | ListCollectionView | ||
Removes the item at the specified index and returns it. | ListCollectionView | ||
Places the item at the specified index. | ListCollectionView | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Returns an Array that is populated in the same order as the IList
implementation. | ListCollectionView | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Prints the contents of this view to a string and returns it. | ListCollectionView | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. | ListCollectionView |
Property Detail

source:Array
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
The source of data in the ArrayCollection. The ArrayCollection object does not represent any changes that you make directly to the source array. Always use the ICollectionView or IList methods to modify the collection.
This property can be used as the source for data binding. When this property is modified, it dispatches the listChanged
event.
Implementation
