Interface ConnectionStateListener

All Known Implementing Classes:

ConnectionManagerImpl

public interface ConnectionStateListener

An internal interface used by the framework - implemented by an object which can be notified when connections are opened or closed.

Note: in practice this is implemented by the ConnectionManager as a means to be notified of connection events, and this interface is invoked by ConnectionListeners when incoming connections are received and by Connection objects when connections are closed.

This interface really only exists to decouple objects which send notifications from the implementations which subscribe to them, to simplify independent unit testing etc.
