abstract fun receivedFrameHandler(handler: Handler<Frame>): StompClientConnection
Configures a received handler that get 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 by the handler.
Unlike StompClient#receivedFrameHandler(Handler), the given handler won't receive the CONNECTED frame. If a received frame handler is set on the StompClient, it will be used by all clients connection, so calling this method is useless, except if you want to use a different handler.
Return
the current StompClientConnection
