Java 1.4

event listener

This interface defines the method that an object must implement if it wants to be notified when a preference key/value pair is added to, removed from, or changed in a Preferences object. After any such change, the Preferences object passes a PreferenceChangeEvent object describing the change to the preferenceChange( ) method of any PreferenceChangeListener objects that have been registered through the Preferences.addPreferenceChangeListener( ) method.
