Class DefaultClusterConfigurationHelper

java.lang.Object

com.atlassian.confluence.cluster.DefaultClusterConfigurationHelper

All Implemented Interfaces:

ClusterConfigurationHelper, ClusterConfigurationHelperInternal

@ParametersAreNonnullByDefault
public class DefaultClusterConfigurationHelper
extends Object
implements ClusterConfigurationHelperInternal

An implementation of ClusterConfigurationHelper which assumes that a cluster of some sort is being used. The specifics of the underlying clustering technology are handled by the ClusterManager. If no cluster is being used, then this class is not appropriate, and NonClusterConfigurationHelper should be used instead.
