Class StandaloneClusterManager

java.lang.Object

com.budjb.spring.distributed.cluster.AbstractClusterManager

com.budjb.spring.distributed.cluster.standalone.StandaloneClusterManager

All Implemented Interfaces:

ClusterManager, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class StandaloneClusterManager
extends AbstractClusterManager
implements org.springframework.context.ApplicationContextAware

An implementation of ClusterManager that only contains a single node. While this class may seem to violate the purpose of the library, this implementation is useful for local developing and testing.
