Example 21 with Socket

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

the class ZThread method fork.

//  --------------------------------------------------------------------------
//  Create an attached thread. An attached thread gets a ctx and a PAIR
//  pipe back to its parent. It must monitor its pipe, and exit if the
//  pipe becomes unreadable. Returns pipe, or null if there was an error.
public static Socket fork(ZContext ctx, IAttachedRunnable runnable, Object... args) {
    Socket pipe = ctx.createSocket(ZMQ.PAIR);
    if (pipe != null) {
        pipe.bind(String.format("inproc://zctx-pipe-%d", pipe.hashCode()));
    } else {
        return null;
    }
    //  Connect child pipe to our pipe
    ZContext ccontext = ZContext.shadow(ctx);
    Socket cpipe = ccontext.createSocket(ZMQ.PAIR);
    if (cpipe == null) {
        return null;

    //  Prepare child thread
    Thread shim = new ShimThread(ccontext, runnable, args, cpipe);
