Class ZLoop

java.lang.Object

org.zeromq.ZLoop

public class ZLoop
extends Object

The ZLoop class provides an event-driven reactor pattern. The reactor handles zmq.PollItem items (pollers or writers, sockets or fds), and once-off or repeated timers. Its resolution is 1 msec. It uses a tickless timer to reduce CPU interrupts in inactive processes.
