Property | Defined By | ||
---|---|---|---|
container : IContainer [read-only]
The container that contains this Repeater,

count : int
The number of times this Repeater should execute. | 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 | ||

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. | IRepeater | ||

Initializes a new Repeater object. | IRepeater |
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
Related API Elements
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

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
executeChildBindings | () | method |
public function executeChildBindings():void
Language Version: | ActionScript 3.0 |
Product Version: | Flex 3 |
Runtime Versions: | Flash Player 9, AIR 1.1 |
Executes the bindings into all the UIComponents created by this Repeater.
This method is called by the Flex framework. Developers should not need to call it.
initializeRepeater | () | method |
public function initializeRepeater(container:IContainer, recurse:Boolean):void
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.
