Examples of FamilyClusterInfo

org.jboss.ha.framework.interfaces.FamilyClusterInfo
Maintain information for a given proxy family. Proxies can statically reference objects implementing this interface: only the content will change as the cluster topology changes, not the FamilyClusterInfo object itself. Proxies or LoadBalancing policy implementations can use the cursor and object attribute to store arbitrary data that is then shared accross all proxies belonging to the same family. Initial access to this object is done through the {@link ClusteringTargetsRepository} singleton. @see org.jboss.ha.framework.interfaces.FamilyClusterInfoImpl @see org.jboss.ha.framework.interfaces.ClusteringTargetsRepository @author Sacha Labourey. @version $Revision: 69400 $
