Class NonReliableRequestReplyReceiver

java.lang.Object

org.fabric3.binding.zeromq.runtime.message.AbstractReceiver

org.fabric3.binding.zeromq.runtime.message.NonReliableRequestReplyReceiver

All Implemented Interfaces:

java.lang.Thread.UncaughtExceptionHandler, Receiver

public class NonReliableRequestReplyReceiver
extends AbstractReceiver
implements java.lang.Thread.UncaughtExceptionHandler

A Receiver that implements request-reply with no qualities of service.

Since ZeroMQ requires the creating socket thread to receive messages, a polling thread is used for reading messages from the ZeroMQ socket. The receiver listens for address updates (e.g. a sender coming online or going away). Since ZeroMQ does not implement disconnect semantics on a socket, if an update is received the original socket will be closed and a new one created to connect to the update set of addresses.
