java.lang.Object
org.jboss.ha.framework.interfaces.FirstAvailableIdenticalAllProxies
- All Implemented Interfaces:
- Serializable, org.jboss.ha.client.loadbalance.LoadBalancePolicy
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)

init
public void init(HARMIClient father)
- Description copied from interface:
LoadBalancePolicy
- Initialize the policy with a reference to its parent stub. the load-balancing policy
implementation can use HARMIClient data to take its decision
- Parameters:
father
- The stub that owns the policy

chooseTarget
public Object chooseTarget(org.jboss.ha.framework.interfaces.FamilyClusterInfo clusterFamily,
Invocation routingDecision)
- Description copied from interface:
LoadBalancePolicy
- Called when the stub wishes to know on which node the next invocation must
be performed.
- Parameters:
clusterFamily
- A list of potential target nodesroutingDecision
- The actual invocation object if the policy wants
to have some kind of invocation-based routing strategy
- Returns:
- The selected target for the next invocation
