Interface DatabaseChangeListener
- All Superinterfaces:
- java.util.EventListener
public interface DatabaseChangeListener
- extends java.util.EventListener
The listener interface for receiving Database Change Notification (DCN)
events. The class that is interested in processing a DCN event implements
this interface, and the object created with that class is registered with
a DatabaseChangeRegistration, using it's
addListener
method. When the DCN event occurs, that object's
onDatabaseChangeNotification
method is invoked.
onDatabaseChangeNotification
void onDatabaseChangeNotification(DatabaseChangeEvent e)
- This method will be invoked whenever a Database Change event occurs. Note that
you can control which thread will invoke this method by specifying
an executor when you register this listener. If the code inside this
method is time/resource consuming, then it is recommended to use your
own thread otherwise you may starve the other listeners.
