Examples of java.util.prefs.NodeChangeEvent

java.util.prefs.NodeChangeEvent
An event emitted by a Preferences node to indicate that a child of that node has been added or removed.
Note, that although NodeChangeEvent inherits Serializable interface from java.util.EventObject, it is not intended to be Serializable. Appropriate serialization methods are implemented to throw NotSerializableException. @author Josh Bloch @version $I$, $G$ @see Preferences @see NodeChangeListener @see PreferenceChangeEvent @since 1.4 @serial exclude
