6.  def binaryHandlerID(): String

   When a `Websocket` is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

   When a `Websocket` is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

   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. * @return the binary handler id

7.  def binaryMessageHandler(handler: Handler[Buffer]): WebSocketBase

   Set a binary message handler on the connection.

   Set a binary message handler on the connection. This handler serves a similar purpose to io.vertx.scala.core.http.WebSocket#handler except that if a message comes into the socket in multiple frames, the data from the frames will be aggregated into a single buffer before calling the handler (using io.vertx.scala.core.http.WebSocketFrame#isFinal to find the boundaries). * @param handler the handler

    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 5.5.2.

    There is no need to manually write a Pong, as the server and client both handle responding to a ping with a pong automatically and this is exposed to users.RFC 6455 Section 5.5.3 states that pongs may be sent unsolicited in order to implement a one way heartbeat. * @param data the data to write, may be at most 125 bytes
