                                                                             org.hibernate.event.spi.DeleteContext transientEntities)

        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 java.util.concurrent.CompletionStage<java.lang.Void> deleteTransientEntity​(org.hibernate.event.spi.EventSource session,
                                                                                     java.lang.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).

        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.
