Method Detail

getObjects

public Collection getObjects()

getLineage

public String getLineage()

isEmpty

public boolean isEmpty()

filter

public RelatedItemsProcessor.ObjectGroup filter(EPMFilter filter)
                                         throws WTException

Filters the list of objects that belong to this group and returns a new ObjectGroup that holds the filtered list of objects. The original group is left unchanged.

Throws:

WTException

filter

public static List filter(Collection groups,
                          EPMFilter filter)
                   throws WTException

Filters each group on the given list. Returns a new list that holds the new filtered groups. The original groups and list are left unchanged.

Throws:

WTException

reconcile

public static void reconcile(Collection firstGroups,
                             Collection secondGroups)

Reconciles the differences between the two sets of groups. If a group in the second set has a different iteration of the same master as a group in the first set, it is replaced with the iteration from the first group. A master in either set is replaced with an iteration from the other.

getAllObjects

public static List getAllObjects(Collection groups)

Returns all of the objects from all of the groups in the given list. Since an object may belong to more than one group, duplicates are removed.

indexByMaster

private static Map indexByMaster(Collection groups)

getKey

private static QueryKey getKey(Persistable object)
