      extended byorg.dom4j.tree.AbstractBranch
          extended byorg.dom4j.tree.AbstractElement
              extended byorg.dom4j.tree.DefaultElement
                  extended byorg.dom4j.util.UserDataElement
All Implemented Interfaces:
Branch, Cloneable, Element, Node, Serializable
public class UserDataElement
extends DefaultElement

UserDataElement support the adornment of a user data object on an Element or Attribute instance such that the methods setData(Object)will get and set the values of a user data object. This can be useful for developers wishing to create XML trees and adorn the trees with user defined objects.
