Example 1 with NaturalIdResolutions

use of org.hibernate.engine.spi.NaturalIdResolutions in project hibernate-orm by hibernate.

the class AbstractEntityPersister method handleNaturalIdReattachment.

private void handleNaturalIdReattachment(Object entity, SharedSessionContractImplementor session) {
    if (naturalIdMapping == null) {
        return;
    }

        return;
    }
    final PersistenceContext persistenceContext = session.getPersistenceContextInternal();
    final NaturalIdResolutions naturalIdResolutions = persistenceContext.getNaturalIdResolutions();
    final Object id = getIdentifier(entity, session);
    // for reattachment of mutable natural-ids, we absolutely positively have to grab the snapshot from the
    // database, because we have no other way to know if the state changed while detached.
    final Object naturalIdSnapshot;
    final Object[] entitySnapshot = persistenceContext.getDatabaseSnapshot(id, this);
    if (entitySnapshot == StatefulPersistenceContext.NO_ROW) {
        naturalIdSnapshot = null;
