Package org.apache.catalina
Interface Cluster
- All Superinterfaces:
- Contained
- All Known Subinterfaces:
- CatalinaCluster
- All Known Implementing Classes:
- SimpleTcpCluster
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:
