Interface WsSessionListener

public interface WsSessionListener

A simple listener that is attached to a single websocket Session.

When a new websocket client connects, this object's sessionAdded() method will be called informing this object that a new client is ready to begin sending commands over the websocket.

When a old websocket client disconnects, this object's sessionRemoved() method will be called informing this object that it should clean up any resources or other connections that are no longer needed now that the client has gone away.

Note on concurrency: The implementors are warranted that sessionAdded() will be called before sessionRemoved() and that there will be no overlapping calls of these methods from distinct threads. Further best effort will be done to call sessionRemoved() for all existing listeners on application exit.
