NAME ^

ZeroMQ::PubSub::Server - Listen for published events and broadcast them to all connected subscribers

SYNOPSIS ^

    use ZeroMQ::PubSub::Server;
    my $server = ZeroMQ::PubSub::Server->new(
        # clients connect here to publish events
        publish_addrs => [ 'tcp://0.0.0.0:4000', 'ipc:///tmp/pub.sock' ],

        # clients connect here to subscribe to events
        subscribe_addrs => [ 'tcp://0.0.0.0:5000', 'ipc:///tmp/sub.sock' ],

        debug => 1,
    );

    # listen for events forever
    {
        # listen for events being published to our server
        my $pub_sock = $self->bind_publish_socket;

        # set up to broadcast events to waiting subscribers
        my $sub_sock = $self->bind_subscribe_socket;

        # main processing loop
        while (1) {
            # block while we get one message
            my $msg = $server->recv;

            # deep clone $msg so that event handlers can't modify it
            my $orig = clone($msg);

            # run event handlers
            $self->dispatch_event($msg);

            # broadcast event to subscribers
            $server->broadcast($orig)
        }
    }

    # exact same as above
    $server->run;
