Interface ClusterListener

All Superinterfaces:
EventListener
All Known Implementing Classes:
ClusterListenerAdapter
public interface ClusterListener extends EventListener
A listener for cluster-related events.

It does not have to be thread-safe. All events received by ClusterListener, ServerListener, ServerMonitorListener are totally ordered (and the event order implies the happens-before order), provided that the listeners are not shared by different MongoClients. This means that even if you have a single class implementing all of ClusterListener, ServerListener, ServerMonitorListener, it does not have to be thread-safe.
