createAutoClusterBackingGroup

public org.rhq.core.domain.resource.group.ResourceGroup createAutoClusterBackingGroup(org.rhq.core.domain.auth.Subject subject,
                                                                             org.rhq.core.domain.resource.group.ClusterKey clusterKey,
                                                                             boolean addResources)

Description copied from interface: ClusterManagerRemote

Given a cluster key create a backing group.

Specified by:

createAutoClusterBackingGroup in interface ClusterManagerRemote

addResources - If true, the new group will be assigned the current resources defined by the clusterKey. Otherwise no resources will be assigned to the new group.

Returns:

the backing group

getAutoClusterBackingGroup

public org.rhq.core.domain.resource.group.ResourceGroup getAutoClusterBackingGroup(org.rhq.core.domain.auth.Subject subject,
                                                                          org.rhq.core.domain.resource.group.ClusterKey clusterKey)

Description copied from interface: ClusterManagerRemote

Return the backing group for the supplied cluster key. Resource membership will represent the resources last set for the group and may not reflect current membership. See ClusterManagerRemote.getAutoClusterResources(Subject, ClusterKey)

Specified by:

getAutoClusterBackingGroup in interface ClusterManagerRemote

Returns:

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

getAutoClusterResources

public List<org.rhq.core.domain.resource.Resource> getAutoClusterResources(org.rhq.core.domain.auth.Subject subject,
                                                                  org.rhq.core.domain.resource.group.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 ClusterManagerRemote.getAutoClusterBackingGroup(Subject, ClusterKey).

Specified by:

getAutoClusterResources in interface ClusterManagerRemote

Returns:

not null

getClusterTree

public org.rhq.core.domain.resource.group.composite.ClusterFlyweight getClusterTree(org.rhq.core.domain.auth.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:

getClusterTree in interface ClusterManagerRemote

Returns:

the tree
