| hasRoot | propriedade |
hasRoot: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
| length | propriedade |
length:int [read-only] The length of the currently parsed collection.
public function get length():int
| 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.
This property can be used as the source for data binding.
public function get showRoot():Boolean
public function set showRoot(value:Boolean):void
| source | propriedade |

The source data of the IHierarchicalCollectionView.

| addChild | () | método |
public function addChild(parent:Object, newChild:Object):Boolean
Adds a child node to a node of the data.
Parâmetros
parent:Object — The Object that defines the parent node.
|
|
newChild:Object — The Object that defines the new node.
|
Boolean — true if the node is added successfully.
|
| addChildAt | () | método |
public function addChildAt(parent:Object, newChild:Object, index:int):Boolean
Add a child node to a node at the specified index. This implementation does the following:
parent is null or undefined,
inserts the child at the
specified index in the collection specified
by source.
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.
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.
index value is greater than the collection
length or number of children in the parent, adds the object as
the last child.
Parâmetros
parent:Object — The Object that defines the parent node.
|
|
newChild:Object — The Object that defines the child node.
|
|
index:int — The 0-based index of where to insert the child node.
|
Boolean — true if the child is added successfully.
|
| closeNode | () | método |
public function closeNode(node:Object):void
Closes a node to hide its children.
Parâmetros
node:Object — The Object that defines the node.
|
| contains | () | método |
public function contains(item:Object):Boolean
Checks the collection for the data item using standard equality test.
Parâmetros
item:Object — The Object that defines the node to look for.
|
Boolean — true if the data item is in the collection,
and false if not.
|
| createCursor | () | método |
public function createCursor():IViewCursor
Returns a new instance of a view iterator over the items in this view.
RetornaIViewCursor — IViewCursor instance.
