Method Summary
public static  voidcomputeAddedRemovedEntityRefsFromNewEntitiesOldRefs(Collection addedEntities, Collection removedEntities, Collection newEntities, Collection oldEntityRefs)
     Fill in the two collections of Entity reference strings - those added in newEntities that were not in oldEntityRefs, and those removed, i.e.
public static  booleanentityCollectionContainsRefString(Collection entities, String entityRef)
     Test a collection of Entity object for the specified entity reference
Parameters:
  entities - The collection (Entity) of entities
Parameters:
  entityRef - The string entity reference to find.
public static  booleanisContainedEntityRefsToEntities(Collection entityRefs, Collection entities)
     See if the collection of entity reference strings is contained in the collection of entities.
Parameters:
  entityRefs - The collection (String) of entity references.
Parameters:
  entities - The collection (Entity) of entity objects.
public static  booleanisEqualEntityRefsToEntities(Collection entityRefs, Collection entities)
     See if the collection of entity reference strings matches completely the collection of Entity objects.
Parameters:
  entityRefs - The collection (String) of entity references.
Parameters:
  entities - The collection (Entity) of entity objects.
public static  booleanisIntersectionEntityRefsToEntities(Collection entityRefs, Collection entities)
     See if the collection of entity reference strings has at least one entity that is in the collection of Entity objects.
Parameters:
  entityRefs - The collection (String) of entity references.
Parameters:
  entities - The collection (Entity) of entity objects.
public static  booleanrefCollectionContainsEntity(Collection refs, Entity entity)
     Test a collection of Entity reference Strings for the specified Entity
Parameters:
  refs - The collection (String) of entity refs
Parameters:
  entity - The Entity to find.
