Examples of ObjectChangeListener

javax.naming.event.ObjectChangeListener
The listener interface to get notification of object change events.
These object change events include naming events with type OBJECT_CHANGED. These events could mean that a bound object has had its attributes changed somehow, or has been replaced altogether. The listener can work out what has changed by querying the NamingEvent object that is passed to the objectChanged notification method.
org.eclipse.persistence.internal.descriptors.changetracking.ObjectChangeListener
Purpose: Define a listener for object change tracking.
Description: Listener is notified on a PropertyChangeEvent from the object it belongs to.
Responsibilities: Set the flag to true when there is any change in the object.
