com.levigo.jadice.web.transport.server.networking.websocket.WebSocketTransportEndpoint
All Implemented Interfaces:
com.levigo.jadice.web.transport.server.session.internal.TransportSession

public class WebSocketTransportEndpoint extends Object implements com.levigo.jadice.web.transport.server.session.internal.TransportSession
The WebSocketTransportEndpoint dispatches all incoming and/or outgoing messages using the WebSocket protocol.

Note: The WebSocket container will instantiate a new instance of this class for each client.

    • open

      public void open(javax.websocket.Session session, String clientId, Long lastEventId, javax.websocket.EndpointConfig config) throws IOException
      This gets called by the WebSocket implementation of the application server, once a session is opened.
      Parameters:
      session - the session which was closed by the WebSocket implementation
      clientId - the identifier of the client, passed with the client request
      lastEventId - the id of the latest event, passed with the client request
      config - the configuration of this endpoint given by the websocket container
      Throws:
      IOException - once an error occurred sending initial messages
    • message

      public void message(javax.websocket.Session session, String message, boolean last)
      This is fired by the WebSocket implementation of the application server, once a message was received.
      Parameters:
      session - this is the WebSocket session for the client that gets injected by the application server
      message - the message that was received from the client
    • message

      public void message(javax.websocket.Session session, javax.websocket.PongMessage pongMsg)
      This is fired by the WebSocket implementation of the application server, once a PongMessage was received.

      A pong is send as an answer of a ping. A Ping frame may serve either as a keepalive or as a means to verify that the remote endpoint is still responsive.

      Parameters:
      session - this is the WebSocket session for the client that gets injected by the application server
      pongMsg - this is the pong message of the WebSocket protocol that was received from the client

      Parameters:
      session - this is the WebSocket session for the client that gets injected by the application server
      t - the error which was thrown by the WebSocket implementation
    • close

      public void close(javax.websocket.Session session)
