public interface Cluster extends Contained
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.
