A Cluster works as a Cluster client/server for the local host Different Cluster implementations can be used to
support different ways to communicate within the Cluster. A Cluster implementation is responsible for setting up a
way to communicate within the Cluster and also supply "ClientApplications" with
ClusterSender used when
sending information in the Cluster and ClusterInfo used for receiving information in the Cluster.- Author:
