        Parameters:

        Returns:
      • binaryHandlerID

        public String binaryHandlerID()
        When a WebSocket is created, it may register an event handler with the event bus - the ID of that handler is given by this method.

        By default, no handler is registered, the feature must be enabled via WebSocketConnectOptions or HttpServerOptions.

        Given this ID, a different event loop can send a binary frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops.

        Specified by:
        binaryHandlerID in interface WebSocketBase
        Returns:
        the binary handler id
      • textHandlerID

        public String textHandlerID()
        When a WebSocket is created, it may register an event handler with the eventbus, the ID of that handler is given by textHandlerID.

        By default, no handler is registered, the feature must be enabled via WebSocketConnectOptions or HttpServerOptions.

        Given this ID, a different event loop can send a text frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops.

        Specified by:
        textHandlerID in interface WebSocketBase
        Returns:
        the text handler id
      • subProtocol

        public String subProtocol()
        Returns the WebSocket sub protocol selected by the WebSocket handshake.

        On the server, the value will be null when the handler receives the WebSocket callback as the handshake will not be completed yet.

        Specified by:
        subProtocol in interface WebSocketBase
        Returns:
      • closeStatusCode

        public Short closeStatusCode()

        Returns the HTTP headers when the WebSocket is first obtained in the handler.

        The headers will be null on subsequent interactions.

        Specified by:
        headers in interface WebSocketBase
        Returns:
        the headers
      • pongHandler

        public WebSocketBase pongHandler​(Handler<Buffer> handler)
        Set a pong frame handler on the connection. This handler will be invoked every time a pong frame is received on the server, and can be used by both clients and servers since the RFC 6455 section 5.5.2 and section 5.5.3 do not specify whether the client or server sends a ping.

        Pong frames may be at most 125 bytes (octets).

        There is no ping handler since ping frames should immediately be responded to with a pong frame with identical content

        Pong frames may be received unsolicited.

        Writes a ping frame to the connection. This will be written in a single frame. Ping frames may be at most 125 bytes (octets).

        This method should not be used to write application data and should only be used for implementing a keep alive or to ensure the client is still responsive, see RFC 6455 Section section 5.5.2.

        There is no handler for ping frames because RFC 6455 clearly states that the only response to a ping frame is a pong frame with identical contents.
