The DefaultDataDescriptor class provides a default implementation for accessing and manipulating data for use in controls such as Tree and Menu. This implementation handles e4x XML and object nodes in similar but different ways. See each method description for details on how the method accesses values in nodes of various types. This class is the default value of the Tree, Menu, MenuBar, and PopUpMenuButton control dataDescriptor properties.

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

If the parent parameter is null or undefined, inserts the child parameter at the specified index in the collection specified by model parameter.
If the parent parameter has a children field or property, the method adds the child parameter to it at the index parameter location. In this case, the model parameter is not required.
If the parent parameter does not have a children field or property, the method adds the children property to the parent. The method then adds the child parameter to the parent at the index parameter location. In this case, the model parameter 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 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 relative to the parent.
