      Handle the given delete event.
      Specified by:

      Parameters:
      event - The delete event to be handled.
      Throws:
      org.hibernate.HibernateException

    • reactiveOnDelete

      public CompletionStage<Void> reactiveOnDelete(org.hibernate.event.spi.DeleteEvent event, org.hibernate.event.spi.DeleteContext transientEntities) throws org.hibernate.HibernateException
      Handle the given delete event. This is the cascaded form.
      Specified by:
      reactiveOnDelete in interface ReactiveDeleteEventListener
      Parameters:
      event - The delete event.
      transientEntities - The cache of entities already deleted
      Throws:
      org.hibernate.HibernateException

    • performDetachedEntityDeletionCheck

      protected void performDetachedEntityDeletionCheck(org.hibernate.event.spi.DeleteEvent event)
      Called when we have recognized an attempt to delete a detached entity.

      This is perfectly valid in Hibernate usage; JPA, however, forbids this. Thus, this is a hook for HEM to affect this behavior.

      Parameters:
      event - The event.

    • deleteTransientEntity

      protected CompletionStage<Void> deleteTransientEntity(org.hibernate.event.spi.EventSource session, Object entity, org.hibernate.persister.entity.EntityPersister persister, org.hibernate.event.spi.DeleteContext transientEntities)
      We encountered a delete request on a transient instance.

      This is a deviation from historical Hibernate (pre-3.2) behavior to align with the JPA spec, which states that transient entities can be passed to remove operation in which case cascades still need to be performed.

      Parameters:
      session - The session which is the source of the event
      entity - The entity being delete processed
      persister - The entity persister
      transientEntities - A cache of already visited transient entities (to avoid infinite recursion).

    • deleteEntity

      protected CompletionStage<Void> deleteEntity(org.hibernate.event.spi.EventSource session, Object entity, org.hibernate.engine.spi.EntityEntry entityEntry, boolean isCascadeDeleteEnabled, boolean isOrphanRemovalBeforeUpdates, org.hibernate.persister.entity.EntityPersister persister, org.hibernate.event.spi.DeleteContext transientEntities)
      Perform the entity deletion. Well, as with most operations, does not really perform it; just schedules an action/execution with the ActionQueue for execution during flush.
      Parameters:
      session - The originating session
      entity - The entity to delete
      entityEntry - The entity's entry in the PersistenceContext
      isCascadeDeleteEnabled - Is delete cascading enabled?
      persister - The entity persister.
      transientEntities - A cache of already deleted entities.
