                                                   ClusterKey clusterKey,
                                                   boolean addResources)

getAutoClusterBackingGroup

public ResourceGroup getAutoClusterBackingGroup(Subject subject,
                                                ClusterKey clusterKey)

Description copied from interface: ClusterManagerRemote

Specified by:

getAutoClusterBackingGroup in interface ClusterManagerRemote

Returns:

The backing group, or null if the key does not have a backing group.

public List<Resource> getAutoClusterResources(Subject subject,
                                              ClusterKey clusterKey)

Description copied from interface: ClusterManagerRemote

Given a cluster key get the auto cluster resource membership. The membership is always determined at call time, regardless of whether a backing group exists. To get the backing group, if it exists, for a cluster key then call #getAutoClusterBackingGroup(String).

Specified by:

getClusterTree

public ClusterFlyweight getClusterTree(Subject subject,
                                       int groupId)

Description copied from interface: ClusterManagerRemote

Load a fully populated tree view of the "cluster nodes" for a cluster group. These are summary nodes and do not contain the actual resources in the group.

Specified by:
