Class FirstAvailableIdenticalAllProxies

java.lang.Object
  org.jboss.ha.framework.interfaces.FirstAvailableIdenticalAllProxies

All Implemented Interfaces:: LoadBalancePolicy, Serializable

public class FirstAvailableIdenticalAllProxies
extends Object
implements LoadBalancePolicy

LoadBalancingPolicy implementation that always favor the first available target i.e. no load balancing occurs. Nevertheless, the first target is randomly selected. This does not mean that fail-over will not occur if the first member in the list dies. In this case, fail-over will occur, and a new target will become the first member and invocation will continously be invoked on the same new target until its death. Each proxy using this policy will *not* elect its own prefered target: the target *is* shared with all proxies that belong to the same family (for a different behaviour please take a look at FirstAvailable)
