Java 1.4

event listener

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.
