Method Detail

getLoadedCollectionPersister

protected static CollectionPersister getLoadedCollectionPersister(PersistentCollection collection,
                                                                  EventSource source)

getLoadedOwnerOrNull

protected static Object getLoadedOwnerOrNull(PersistentCollection collection,
                                             EventSource source)

getLoadedOwnerIdOrNull

protected static Serializable getLoadedOwnerIdOrNull(PersistentCollection collection,
                                                     EventSource source)

getOwnerIdOrNull

protected static Serializable getOwnerIdOrNull(Object owner,
                                               EventSource source)

getAffectedOwnerEntityName

protected static String getAffectedOwnerEntityName(CollectionPersister collectionPersister,
                                                   Object affectedOwner,
                                                   EventSource source)

getCollection

public PersistentCollection getCollection()

getAffectedOwnerOrNull

public Object getAffectedOwnerOrNull()

Get the collection owner entity that is affected by this event.

Returns:

the affected owner; returns null if the entity is not in the persistence context (e.g., because the collection from a detached entity was moved to a new owner)

getAffectedOwnerIdOrNull

public Serializable getAffectedOwnerIdOrNull()

Get the ID for the collection owner entity that is affected by this event.

Returns:

the affected owner ID; returns null if the ID cannot be obtained from the collection's loaded key (e.g., a property-ref is used for the collection and does not include the entity's ID)

getAffectedOwnerEntityName

public String getAffectedOwnerEntityName()

Get the entity name for the collection owner entity that is affected by this event.

Returns:

the entity name; if the owner is not in the PersistenceContext, the returned value may be a superclass name, instead of the actual class name
