java.util.prefs
Class PreferenceChangeEvent
- Serializable
ObjectEvent fired when a Preferences entry changes.
This event is generated when a entry is added, changed or removed.
When an entry is removed then
getNewValue will return null.
Preference change events are only generated for entries in one particular
preference node. Notification of subnode addition/removal is given by a
NodeChangeEvent.
Note that although this class is marked as serializable, attempts to
serialize it will fail with NotSerializableException.
