IRepeater
  currentIndex : int
[read-only] The index of the item in the dataProvider currently being processed while this Repeater is executing.
IRepeater
  currentItem : Object
[read-only] The item in the dataProvider currently being processed while this Repeater is executing.
IRepeater
  dataProvider : Object
The data provider used by this Repeater to create repeated instances of its children.
IRepeater
  recycleChildren : Boolean
A Boolean flag indicating whether this Repeater should re-use previously created children, or create new ones.

Property Detail

container

property
container:IContainer  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The container that contains this Repeater, and in which it will create its children.



Implementation
    public function get container():IContainer

count

property 
count:int

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The number of times this Repeater should execute.

If the Repeater reaches the end of the data provider while executing, the number of times it actually executes will be less that the requested count.



Implementation
    public function get count():int
    public function set count(value:int):void

currentIndex

property 
currentIndex:int  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The index of the item in the dataProvider currently being processed while this Repeater is executing.

After the Repeater has finished executing, this property is -1. However, the repeaterIndex property of a repeated component instance remembers the index of the dataProvider item from which it was created. In the case of nested Repeaters, you can use the repeaterIndices array.



Implementation
    public function get currentIndex():int

See also

currentItem

property 
currentItem:Object  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The item in the dataProvider currently being processed while this Repeater is executing.

After the Repeater has finished executing, this property is null. However, in this case you can call the getRepeaterItem() method of the repeated component instance to get the dataProvider item from which it was created.



Implementation
    public function get currentItem():Object

See also

dataProvider

property 
dataProvider:Object

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The data provider used by this Repeater to create repeated instances of its children.

If you read the dataProvider property, you always get an ICollectionView object or null. If you set the dataProvider property to anything other than null, it is converted into an ICollectionView object, according the following rules:

  • If you set it to an Array, it is converted into an ArrayCollection.
  • If you set it to an ICollectionView, no conversion is performed.
  • If you set it to an IList, it is converted into a ListCollectionView.
  • If you set it to an XML or XMLList, it is converted into an XMLListCollection.
  • Otherwise, it is converted to a single-element ArrayCollection.

You must specify a value for the dataProvider property or the Repeater component will not execute.



Implementation
    public function get dataProvider():Object
    public function set dataProvider(value:Object):void

recycleChildren

property 
recycleChildren:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

A Boolean flag indicating whether this Repeater should re-use previously created children, or create new ones.

If true, when this Repeater's dataProvider, startingIndex, or count changes, it will recycle the existing children by binding the new data into them. If more children are required, they are created and added. If fewer children are required, the extra ones are removed and garbage collected.

If false, when this Repeater's dataProvider, startingIndex, or count changes, it will remove any previous children that it created and then create and add new children from the new data items.

This property is false by default. Setting it to true can increase performance, but is not appropriate in all situations. For example, if the previously created children have state information such as text typed in by a user, then this state will not get reset when the children are recycled.



Implementation
    public function get recycleChildren():Boolean
    public function set recycleChildren(value:Boolean):void

startingIndex

property 
startingIndex:int

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The index into the dataProvider at which this Repeater starts creating children.



Implementation
    public function get startingIndex():int
    public function set startingIndex(value:int):void
Method Detail

executeChildBindings

()method
public function executeChildBindings():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Initializes a new Repeater object.

This method is called by the Flex framework. Developers should not need to call it.

Parameters

container:IContainer — The Container that contains this Repeater, and in which this Repeater will create its children.
 
recurse:Boolean — A Boolean flag indicating whether this Repeater should create all descendants of its children.
