public interface ObjectChangeListener extends NamingListener
An OBJECT_CHANGED event type is fired when (the contents of) an object has changed. This might mean that its attributes have been modified, added, or removed, and/or that the object itself has been replaced. How the object has changed can be determined by examining the NamingEvent's old and new bindings.
A listener interested in OBJECT_CHANGED event types must:
void objectChanged(NamingEvent evt)
The binding of the changed object can be obtained using evt.getNewBinding(). Its old binding (before the change) can be obtained using evt.getOldBinding().
evt- The nonnull naming event.
