      public Object getAffectedOwnerOrNull()
      Get the collection owner entity that is affected by this event.
      Returns:
      the affected owner; returns null if the entity is not in the persistence context (e.g., because the collection from a detached entity was moved to a new owner)

      public Serializable getAffectedOwnerIdOrNull()
      Get the ID for the collection owner entity that is affected by this event.
      Returns:
      the affected owner ID; returns null if the ID cannot be obtained from the collection's loaded key (e.g., a property-ref is used for the collection and does not include the entity's ID)

    • getAffectedOwnerEntityName

      public String getAffectedOwnerEntityName()
      Get the entity name for the collection owner entity that is affected by this event.
      Returns:
      the entity name; if the owner is not in the PersistenceContext, the returned value may be a superclass name, instead of the actual class name
