Examples of org.jboss.ha.client.loadbalance.RoundRobin

org.jboss.ha.client.loadbalance.RoundRobin
LoadBalancePolicy implementation that always favors the next available target in the list, ensuring maximum load balancing always occurs.
Different instances of this class will coordinate their target selection via the {@link FamilyClusterInfo#getCursor() FamilyClusterInfo cursor}, so if proxy A makes the first call to target 1, and proxy B makes the next call, it will invoke on target 2; the third call will go to target 3 no matter which proxy makes it, and so on.

The first target in the round-robin is chosen randomly, ensuring that proper load balancing occurs when many clients in different VM's download the proxy.
