Descrizione delle proprietà

container

proprietà
container:IContainer  [sola lettura]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

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



Implementazione
    public function get container():IContainer

count

proprietà 
count:int

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: 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.



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

currentIndex

proprietà 
currentIndex:int  [sola lettura]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: 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.



Implementazione
    public function get currentIndex():int

currentItem

proprietà 
currentItem:Object  [sola lettura]

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: 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.

    public function get currentItem():Object

Elementi API correlati

dataProvider

proprietà 
dataProvider:Object

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: 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.



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

recycleChildren

proprietà 
recycleChildren:Boolean

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: 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.



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

startingIndex

proprietà 
startingIndex:int

Versione linguaggio: ActionScript 3.0
Versione prodotto: Flex 3
Versioni runtime: Flash Player 9, AIR 1.1

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



Implementazione
    public function get startingIndex():int
    public function set startingIndex(value:int):void

recurse:Boolean — A Boolean flag indicating whether this Repeater should create all descendants of its children.





[ X ]Perché in inglese?
Il contenuto della Guida di riferimento di ActionScript 3.0 appare in inglese

Non tutte le parti della Guida di riferimento di ActionScript 3.0 sono tradotte in tutte le lingue. Quando un elemento del linguaggio non è tradotto, viene riportato in inglese. Ad esempio, la classe ga.controls.HelpBox non è tradotta in nessuna lingua. Pertanto, nella versione italiana della guida di riferimento, la descrizione della classe ga.controls.HelpBox è riportata in inglese.
