      Returns:
      this

    • handshake

      boolean handshake(javax.servlet.http.HttpServletRequest request)
      Determine if the WebSocket's handshake data can be processed, or if the request be cancelled. Since it's container related native API, the HttpServletRequest might be null, so implementation must check for null.

      WebSocketProcessor registerWebSocketHandler(String path, WebSocketProcessor.WebSocketHandlerProxy webSockethandler)
      Register a WebSocketHandler
      Parameters:
      path - the URI mapping the WebSocketHandler
      webSockethandler - an instance of WebSocketProcessor.WebSocketHandlerProxy
      Returns:
      this
