Example 1 with EntityReturnImpl

use of org.hibernate.loader.plan.build.internal.returns.EntityReturnImpl in project hibernate-orm by hibernate.

the class AbstractLoadPlanBuildingAssociationVisitationStrategy method startingEntity.

// Entities  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

        return;
    }
    // if we get here, it is a root
    log.tracef("%s Starting root entity : %s", StringHelper.repeat(">>", fetchSourceStack.size()), entityDefinition.getEntityPersister().getEntityName());
    if (!supportsRootEntityReturns()) {
        throw new HibernateException("This strategy does not support root entity returns");
    }
    final EntityReturnImpl entityReturn = new EntityReturnImpl(entityDefinition, querySpaces);
    addRootReturn(entityReturn);
    pushToStack(entityReturn);
    // also add an AssociationKey for the root so we can later on recognize circular references back to the root.
    final Joinable entityPersister = (Joinable) entityDefinition.getEntityPersister();
    associationKeyRegistered(new AssociationKey(entityPersister.getTableName(), entityPersister.getKeyColumnNames()));
