Examples with PollItem org.zeromq.ZMQ.PollItem used on opensource projects

Example 6 with PollItem

use of org.zeromq.ZMQ.PollItem in project jeromq by zeromq.

the class bstar method voter.

//  .split voter method
//  This method registers a client voter socket. Messages received
//  on this socket provide the CLIENT_REQUEST events for the Binary Star
//  FSM and are passed to the provided application handler. We require
//  exactly one voter per {{bstar}} instance:
public int voter(String endpoint, int type, IZLoopHandler handler, Object arg) {
    //  Hold actual handler+arg so we can call this later
    Socket socket = ctx.createSocket(type);
    socket.bind(endpoint);
    voterFn = handler;
    voterArg = arg;
    PollItem poller = new PollItem(socket, ZMQ.Poller.POLLIN);
    return loop.addPoller(poller, VoterReady, this);
}
