Example 1 with ValueReference

use of zmq.util.ValueReference in project jeromq by zeromq.

the class Server method xrecv.

@Override
protected Msg xrecv() {
    Msg msg;
    ValueReference<Pipe> pipe = new ValueReference<>();
    msg = fq.recvPipe(errno, pipe);
    // Drop any messages with more flag
    while (msg != null && msg.hasMore()) {
        // drop all frames of the current multi-frame message
        msg = fq.recvPipe(errno, null);
        while (msg != null && msg.hasMore()) {
            msg = fq.recvPipe(errno, null);
        }
        // get the new message
        if (msg != null) {
            msg = fq.recvPipe(errno, pipe);
        }
    }
    if (msg == null) {
        return msg;
    }
    assert (pipe.get() != null);
    int routingId = pipe.get().getRoutingId();
    msg.setRoutingId(routingId);
    return msg;
}
