ClusteringTargetsRepositorypublic class ClusteringTargetsRepository extends Object | JVM singleton that associates a list of targets (+ other info)
contained in a FamilyClusterInfo to a proxy family. For example
All remote proxies for a given EJB in a given cluster are part of the
same proxy family. Note that home and remote for a same EJB form *2*
proxy families. |
