Method Details

getInitializor

protected Initializor<T> getInitializor(EnversService enversService,
 AuditReaderImplementor versionsReader,
 Object primaryKey,
 Number revision,
 boolean removed)

Specified by:

getInitializor in class AbstractCollectionMapper<T extends Map>

getNewCollectionContent

protected Collection getNewCollectionContent(org.hibernate.collection.spi.PersistentCollection newCollection)

Specified by:

getNewCollectionContent in class AbstractCollectionMapper<T extends Map>

getOldCollectionContent

protected Collection getOldCollectionContent(Serializable oldCollection)

Specified by:

getOldCollectionContent in class AbstractCollectionMapper<T extends Map>

mapToMapFromObject

protected void mapToMapFromObject(org.hibernate.engine.spi.SessionImplementor session,
 Map<String,Object> idData,
 Map<String,Object> data,
 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)

Specified by:

buildCollectionChangeSet in class AbstractCollectionMapper<T extends Map>

isSame

protected boolean isSame(org.hibernate.persister.collection.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.

mapCollectionChanges

public List<PersistentCollectionChangeData> mapCollectionChanges(org.hibernate.engine.spi.SessionImplementor session,
 org.hibernate.collection.spi.PersistentCollection newColl,
 Serializable oldColl,
 Object id)

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.
