| compareTo | | public int compareTo(Cloud o)(Code) | | Compares this cloud to the passed object.
Returns 0 if they are equal, -1 if the object passed is a Cloud and larger than this cloud,
and +1 if the object passed is a Cloud and smaller than this cloud.
Parameters:
o - the object to compare it with compare number |
| contains | | boolean contains(MMObjectNode node)(Code) | | Checks wether the current transaction contains the given node.
|
| createAggregatedQuery | | public Query createAggregatedQuery()(Code) | | |

| getClusterNodes | | protected List<MMObjectNode> getClusterNodes(Query query)(Code) | | Result with all Cluster - MMObjectNodes, with cache. Security is not considered here (the
query is executed thoughtlessly). The security check is done in getSecureNodes, which calls
this one.
Parameters:
query - query to execute list of cluster nodes

| getLastStepList | | protected NodeList getLastStepList(Query query)(Code) | | Based on multi-level query. Returns however 'normal' nodes based on the last step. This is a
protected function, which is used in the implemetnedion of getRelatedNodes, getRelations of
NodeManager
Before it executes the query, the fields of the query are checked. All and only fields of the
'last' NodeManager and the relation should be queried. If fields are present already, but
not like this, an exception is thrown. If not fields are present, the rights fields are added
first (if the query is still unused, otherwise trhows Exception).
Parameters:
query - query to execute list of normal nodes
throws:
BridgeException - If wrong fields in query or could not be added.
since:
MMBase-1.7 |

Note that you can retrieve a manager with source and destination reversed.
Parameters:
sourceManagerId - number of the NodeManager of the source node
Parameters:
destinationManagerId - number of the NodeManager of the destination node
Parameters:
roleId - number of the role the requested RelationManager |
