The IRepeater interface defines the APIs for Repeater
public APIs of the Repeater object.
container:IContainer [read-only]
The container that contains this Repeater,
and in which it will create its children.
Implementation
public function get container():IContainer
count:int [read-write]
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:int [read-only]
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:Object [read-only]
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:Object [read-write]
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:Boolean [read-write]
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:int [read-write]
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
public function executeChildBindings():void
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.
public function initializeRepeater(container:IContainer, recurse:Boolean):void
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.
