container:IContainer [skrivskyddad] | Språkversion: | ActionScript 3.0 |

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

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.

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.

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.

dataProvider | egenskap |
dataProvider:Object| Språkversion: | ActionScript 3.0 |
| Produktversion: | Flex 3 |
| Körningsmiljöversioner: | 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.

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.

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