A
NodeChangeEvent

object is passed to the methods of any
NodeChangeListener objects registered on a
Preferences object when a child
Preferences node is added or removed.
getChild( ) returns the
Preferences object that was added or removed.
getParent( ) returns the parent
Preferences node from which the child was added or
removed. This parent Preferences object is the one
on which the NodeChangeListener was registered.

Although this class inherits the Serializable
interface, it is not actually serializable.
