Class NonClusterConfigurationHelper

java.lang.Object

com.atlassian.confluence.cluster.nonclustered.NonClusterConfigurationHelper

All Implemented Interfaces:

ClusterConfigurationHelper, ClusterConfigurationHelperInternal

public class NonClusterConfigurationHelper
extends Object
implements ClusterConfigurationHelperInternal

An implementation of ClusterConfigurationHelper for use when clustering is not being used. Some methods may throw exceptions if they are used, so isClusteredInstance() should be used to check in advance if the other methods are appropriate to use.
