IEndpointLifecycleSubscriber (apache-cassandra API)

All Known Implementing Classes:

Server.EventNotifier
```
public interface IEndpointLifecycleSubscriber
```
Interface on which interested parties can be notified of high level endpoint state changes. Note that while IEndpointStateChangeSubscriber notify about gossip related changes (IEndpointStateChangeSubscriber.onJoin() is called when a node join gossip), this interface allows to be notified about higher level events.
