public class TopicLoadBalancer
extends LoadBalancerSupport

A LoadBalancer implementations which sends to all destinations (rather like JMS Topics).

The MulticastProcessor is more powerful as it offers option to run in parallel and decide whether or not to stop on failure etc.

Strategy method to copy the exchange before sending to another endpoint. Derived classes such as the Pipeline will not clone the exchange

Parameters:

processor - the processor that will send the exchange

exchange - the exchange
