Class CollectionCacheInvalidator

java.lang.Object

org.hibernate.cache.internal.CollectionCacheInvalidator

All Implemented Interfaces:

Serializable, PostDeleteEventListener, PostInsertEventListener, PostUpdateEventListener, Integrator

public class CollectionCacheInvalidator
extends Object
implements Integrator, PostInsertEventListener, PostDeleteEventListener, PostUpdateEventListener

Allows the collection cache to be automatically evicted if an element is inserted/removed/updated *without* properly managing both sides of the association (ie, the ManyToOne collection is changed w/o properly managing the OneToMany). For this functionality to be used, AvailableSettings.AUTO_EVICT_COLLECTION_CACHE must be enabled. For performance reasons, it's disabled by default.

Methods

Modifier and Type	Method and Description
void	disintegrate(SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) Tongue-in-cheek name for a shutdown callback.
void	integrate(Configuration configuration, SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) Perform integration.
void	integrate(MetadataImplementor metadata, SessionFactoryImplementor sessionFactory, SessionFactoryServiceRegistry serviceRegistry) Perform integration.
void	onPostDelete(PostDeleteEvent event)
void	onPostInsert(PostInsertEvent event)
void	onPostUpdate(PostUpdateEvent event)
boolean	requiresPostCommitHanding(EntityPersister persister) Does this listener require that after transaction hooks be registered? Typically this is true for post-insert event listeners, but may not be, for example, in JPA cases where there are no callbacks defined for the particular entity.
