Examples of org.zeromq.ZMsg.unwrap()

org.zeromq.ZMsg.unwrap()
Pop frame off front of message, caller now owns frame. If next frame is empty, pops and destroys that empty frame (e.g. useful when unwrapping ROUTER socket envelopes) @return Unwrapped frame

            ZMsg msg = null;
            if (backends[0].isReadable()) {
                msg = ZMsg.recvMsg(localbe);
                if (msg == null)
                    break;          //  Interrupted
                ZFrame address = msg.unwrap();
                workers.add(address);
                capacity++;


                //  If it's READY, don't route the message any further
                ZFrame frame = msg.getFirst();
