Interface FamilyClusterInfo

All Known Implementing Classes:: FamilyClusterInfoImpl

public interface 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 ClusteringTargetsRepository singleton.
