Interface providing methods for parsing and adding nodes
to a collection of data that is displayed by a Tree control.
public function addChildAt(parent:Object, newChild:Object, index:int, model:Object = null):Boolean
Adds a child node to a node at the specified index.
Parameters
| parent:Object — The node object that will parent the child.
|
| |
| newChild:Object — The node object that will be parented by the node.
|
| |
| index:int — The 0-based index of where to put the child node.
|
| |
| model:Object (default = null) |
Returns
public function getChildren(node:Object, model:Object = null):ICollectionView
Provides access to a node's children, returning a collection
view of children if they exist.
A node can return any object in the collection as its children;
children need not be nested.
It is best-practice to return the same collection view for a
given node.
Parameters
| node:Object — The node object currently being evaluated.
|
| |
| model:Object (default = null) |
Returns
public function getData(node:Object, model:Object = null):Object
Gets the data from a node.
Parameters
| node:Object — The node object from which to get the data.
|
| |
| model:Object (default = null) |
Returns
| Object — Object The requested data.
|
public function hasChildren(node:Object, model:Object = null):Boolean
Tests for the existence of children in a non-terminating node.
Parameters
Returns
public function isBranch(node:Object, model:Object = null):Boolean
Tests a node for termination.
Branches are non-terminating but are not required
to have any leaf nodes.
Parameters
| node:Object — The node object currently being evaluated.
|
| |
| model:Object (default = null) |
Returns
| Boolean — A Boolean indicating if this node is non-terminating.
|
public function removeChildAt(parent:Object, child:Object, index:int, model:Object = null):Boolean
Removes a child node to a node at the specified index.
Parameters
| parent:Object — The node object that is the parent of the child.
|
| |
| child:Object — The node object that will be removed.
|
| |
| index:int — The 0-based index of the soon to be deleted node.
|
| |
| model:Object (default = null) |
Returns
