Esconder Propriedades Públicas Herdadas
Exibir Propriedades Públicas HerdadashasRoot:Boolean [read-only]
A flag that, if true, indicates that the current data provider has a root node;
for exemplo, 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.
public function get hasRoot():Boolean
| openNodes | propriedade |
openNodes:Object [read-write] An Array of Objects containing the data provider element for all the open branch nodes of the data.
public function get openNodes():Object
public function set openNodes(value:Object):void
| showRoot | propriedade |
showRoot:Boolean [read-write]
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.
The default value is true.
public function get showRoot():Boolean
public function set showRoot(value:Boolean):void
