## org.dom4j.util
Class UserDataElement

    java.lang.Object
      org.dom4j.tree.AbstractNode
          org.dom4j.tree.AbstractBranch
              org.dom4j.tree.AbstractElement
                  org.dom4j.tree.DefaultElement
                      org.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.
