Example 11 with PollItem

use of org.zeromq.ZMQ.PollItem in project aion by aionnetwork.

the class ZLoop method addPoller.

// --------------------------------------------------------------------------

// the handler, passing the arg. Returns 0 if OK, -1 if there was an error.
// If you register the pollitem more than once, each instance will invoke its
// corresponding handler.
