This
interface
defines the methods that an object must implement if it wants to be
notified when a child preferences node is added to or removed from a
Preferences object. When such an addition or
removal occurs, the parent Preferences object
passes a NodeChangeEvent object to the appropriate
method of any NodeChangeListener objects that have
been registered through the
Preferences.addNodeChangeListener( ) method.
