      • onClose

        public void onClose​(Session session,
                            CloseReason closeReason)
        Description copied from class: Endpoint
        This method is called immediately prior to the session with the remote peer being closed. It is called whether the session is being closed because the remote peer initiated a close and sent a close frame, or whether the local websocket container or this endpoint requests to close the session. The developer may take this last opportunity to retrieve session attributes such as the ID, or any application data it holds before it becomes unavailable after the completion of the method. Developers should not attempt to modify the session from within this method, or send new messages from this call as the underlying connection will not be able to send them at this stage.
        Overrides:
        onClose in class Endpoint
        Parameters:
        session - the session about to be closed.
        closeReason - the reason the session was closed.
      • onError

        public void onError​(Session session,
                            java.lang.Throwable thr)
        Description copied from class: Endpoint
        Developers may implement this method when the web socket session creates some kind of error that is not modeled in the web socket protocol. This may for example be a notification that an incoming message is too big to handle, or that the incoming message could not be encoded.

        There are a number of categories of exception that this method is (currently) defined to handle:

        • connection problems, for example, a socket failure that occurs before the web socket connection can be formally closed. These are modeled as SessionExceptions
        • runtime errors thrown by developer created message handlers calls.
        • conversion errors encoding incoming messages before any message handler has been called. These are modeled as DecodeExceptions
        Overrides:
        onError in class Endpoint
        Parameters:
        session - the session in use when the error occurs.
        thr - the throwable representing the problem.
      • onOpen

        public void onOpen​(Session session,
                           EndpointConfig configuration)
        Description copied from class: Endpoint
        Developers must implement this method to be notified when a new conversation has just begun.

        Note:

        • It is permitted to send messages from this method.
        • It is permitted to add MessageHandlers from this method. No messages will be mapped to the appropriate MessageHandler until this method has completed.
        Specified by:
        onOpen in class Endpoint
        Parameters:
        session - the session that has just been activated.
        configuration - the configuration used to configure this endpoint.
