      Like `connect(int, String, Handler)` but returns a `Future` of the asynchronous result

    - #### connect

          StompClient connect(NetClient net,
                              Handler<AsyncResult<StompClientConnection>> resultHandler)

        `resultHandler` - handler called with the connection result
      Returns:
        the current `StompClient`

    - #### connect

          Future<StompClientConnection> connect(NetClient net)

      Like `connect(NetClient, Handler)` but returns a `Future` of the asynchronous result

    - #### connect

          StompClient connect(int port,

                              Handler<AsyncResult<StompClientConnection>> resultHandler)

      Connects to the server.
      Parameters:
        `port` - the server port
        `host` - the server host
        `net` - the NET client to use
        `resultHandler` - handler called with the connection result

    - #### connect

          StompClient connect(Handler<AsyncResult<StompClientConnection>> resultHandler)

      Connects to the server using the host and port configured in the client's options.
      Parameters:
        `resultHandler` - handler called with the connection result. A failure will be sent to the handler if a TCP level issue happen before the `CONNECTED` frame is received. Afterwards, the `exceptionHandler(Handler)` is called.
      Returns:
        the current `StompClient`

    - #### connect

          Future<StompClientConnection> connect()

      Like `connect(Handler)` but returns a `Future` of the asynchronous result

    - #### receivedFrameHandler

          StompClient receivedFrameHandler(Handler<Frame> handler)

      Configures a received handler that gets notified when a STOMP frame is received by the client. This handler can be used for logging, debugging or ad-hoc behavior. The frame can still be modified at the time.

      When a connection is created, the handler is used as `StompClientConnection.receivedFrameHandler(Handler)`.

      Parameters:
        `handler` - the handler
      Returns:
        the current `StompClient`

    - #### writingFrameHandler

          StompClient writingFrameHandler(Handler<Frame> handler)

      Configures a writing handler that gets notified when a STOMP frame is written on the wire. This handler can be used for logging, debugging or ad-hoc behavior. The frame can still be modified at the time.

      When a connection is created, the handler is used as `StompClientConnection.writingFrameHandler(Handler)`.

      Parameters:
        `handler` - the handler
      Returns:
        the current `StompClient`

    - #### errorFrameHandler

          StompClient errorFrameHandler(Handler<Frame> handler)

      A general error frame handler. It can be used to catch `ERROR` frame emitted during the connection process (wrong authentication). This error handler will be pass to all `StompClientConnection` created from this client. Obviously, the client can override it when the connection is established.
      Parameters:
        `handler` - the handler
      Returns:
        the current `StompClient`

    - #### exceptionHandler

          StompClient exceptionHandler(Handler<Throwable> handler)

      Sets an exception handler notified for TCP-level errors.
      Parameters:
        `handler` - the handler
      Returns:
        the current `StompClient`

    - #### close

          void close()

      Closes the client.

    - #### options

          StompClientOptions options()

      Returns:
        the client's options.

    - #### vertx

          Vertx vertx()

      Returns:
        the vert.x instance used by the client.

    - #### isClosed

          boolean isClosed()

      Returns:
        whether or not the client is connected to the server.
