Class AjaxTreeModel.WrapperNode

java.lang.Object
  er.ajax.AjaxTreeModel.WrapperNode

Enclosing class:

AjaxTreeModel

public abstract static class AjaxTreeModel.WrapperNode
extends java.lang.Object

WrapperNode is useful if your objects form a graph instead of a tree and you want to maintain the unique branching to a particular node as the user navigates through the tree. isLeaf has a default implementation that you may want to overried if you can provide a "smarter" implementation.
