FirstAvailableIdenticalAllProxiespublic 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) |
