Method Detail
addChildAt | () | method |
public function addChildAt(parent:Object, newChild:Object, index:int, model:Object = null):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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) |
Boolean — true if successful.

getChildren | () | method |
public function getChildren(node:Object, model:Object = null):ICollectionView| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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) |
ICollectionView — An collection view containing the child nodes.
|
getData | () | method |
public function getData(node:Object, model:Object = null):Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Gets the data from a node.
Parameters
node:Object — The node object from which to get the data.
| |
model:Object (default = null) |
Object — The requested data.
|
hasChildren | () | method |
public function hasChildren(node:Object, model:Object = null):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Tests for the existence of children in a non-terminating node.
Parameters
node:Object — The current node.
| |
model:Object (default = null) |
Boolean — true if the node has at least one child.
|
isBranch | () | method |
public function isBranch(node:Object, model:Object = null):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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) |
Boolean — A Boolean indicating if this node is non-terminating.
|
removeChildAt | () | method |
public function removeChildAt(parent:Object, child:Object, index:int, model:Object = null):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
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) |
Boolean — true if successful.
