public class UITreeData

implements javax.faces.component.NamingContainer, org.apache.myfaces.custom.tree2.Tree, javax.faces.component.UniqueIdVendor

TreeData is a UIComponent that supports binding data stored in a tree represented by a TreeNode instance. During iterative processing over the tree nodes in the data model, the object for the current node is exposed as a request attribute under the key specified by the var property. Renderers of this component should use the appropriate facet to assist in rendering.
