런타임 버전:

Flash Player 9, AIR 1.1

A flag that, if true, indicates that the current data provider has a root node; for example, a single top-level node in a hierarchical structure. XML and Object are examples of data types that have a root node, while Lists and Arrays do not.

구현
public function get hasRoot():Boolean

언어 버전:

ActionScript 3.0

제품 버전:

showRoot

속성

showRoot:Boolean

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

A Boolean flag that specifies whether to display the data provider's root node. If the source data has a root node, and this property is set to false, the collection will not include the root item. Only the descendants of the root item will be included in the collection.

This property has no effect on a source with no root node, such as List and Array objects.

기본값: true.

이 속성은 데이터 바인딩에 대한 소스로 사용할 수 있습니다. 이 속성을 수정하면 propertyChange 이벤트를 전달합니다.

Add a child node to a node at the specified index. This implementation does the following:

If the parent is null or undefined, inserts the child at the specified index in the collection specified by source.
If the parent has a children field or property, the method adds the child to it at the index location. In this case, the source is not required.
If the parent does not have a children field or property, the method adds the children to the parent. The method then adds the child to the parent at the index location. In this case, the source is not required.
If the index value is greater than the collection length or number of children in the parent, adds the object as the last child.

매개 변수

	`parent:Object` — The Object that defines the parent node.

	`newChild:Object` — The Object that defines the child node.

제품 버전:

Applies the sort and filter to the view. The ICollectionView does not detect changes to a sort or filter automatically, so you must call the refresh() method to update the view after setting the sort or filterFunction property. If your ICollectionView implementation also implements the IMXMLObject interface, you should to call the refresh() method from your initialized() method.

Returns true if the refresh was successful and false if the sort is not yet complete (e.g., items are still pending). A client of the view should wait for a CollectionEvent event with the CollectionEventKind.REFRESH kind property to ensure that the refresh() operation is complete.

반환값

Boolean — true if the refresh() was complete, false if the refresh() is incomplete.
