                                  Object changed)

Description copied from class: AbstractCollectionMapper

Maps the changed collection element to the given map.

Specified by:

mapToMapFromObject in class AbstractCollectionMapper<T extends Map>

idData - Map to which composite-id data should be added.

data - Where to map the data.

changed - The changed collection element to map.

buildCollectionChangeSet

protected Set<Object> buildCollectionChangeSet(Object eventCollection,
                                               Collection collection)

isSame

protected boolean isSame(CollectionPersister collectionPersister,
                         Object oldObject,
                         Object newObject)

Description copied from class: AbstractCollectionMapper

Checks whether the old collection element and new collection element are the same. By default, this delegates to the collection persister's CollectionPersister.getElementType().

Overrides:

isSame in class AbstractCollectionMapper<T extends Map>

Parameters:

collectionPersister - The collection persister.

oldObject - The collection element from the old persistent collection.

newObject - The collection element from the new persistent collection.

Returns:

true if the two objects are the same, false otherwise.

Description copied from class: AbstractCollectionMapper

Map collection changes using hash identity.

Specified by:

mapCollectionChanges in class AbstractCollectionMapper<T extends Map>

Parameters:

session - The session.

newColl - The new persistent collection.

oldColl - The old collection.

id - The owning entity identifier.

Returns:

the persistent collection changes.
