Example 6 with AliasResolutionContextImpl

use of org.hibernate.loader.plan.exec.internal.AliasResolutionContextImpl in project hibernate-orm by hibernate.

the class LoadPlanBuilderTest method testCascadeBasedBuild.

@Test
public void testCascadeBasedBuild() {
    EntityPersister ep = (EntityPersister) sessionFactory().getClassMetadata(Message.class);
    CascadeStyleLoadPlanBuildingAssociationVisitationStrategy strategy = new CascadeStyleLoadPlanBuildingAssociationVisitationStrategy(CascadingActions.MERGE, sessionFactory(), LoadQueryInfluencers.NONE, LockMode.NONE);
    LoadPlan plan = MetamodelDrivenLoadPlanBuilder.buildRootEntityLoadPlan(strategy, ep);
    assertFalse(plan.hasAnyScalarReturns());
    assertEquals(1, plan.getReturns().size());
    Return rtn = plan.getReturns().get(0);
    EntityReturn entityReturn = ExtraAssertions.assertTyping(EntityReturn.class, rtn);
    assertNotNull(entityReturn.getFetches());
    assertEquals(1, entityReturn.getFetches().length);
    Fetch fetch = entityReturn.getFetches()[0];
    EntityFetch entityFetch = ExtraAssertions.assertTyping(EntityFetch.class, fetch);
    assertNotNull(entityFetch.getFetches());
    assertEquals(0, entityFetch.getFetches().length);
    LoadPlanTreePrinter.INSTANCE.logTree(plan, new AliasResolutionContextImpl(sessionFactory()));
}

Example 7 with AliasResolutionContextImpl

use of org.hibernate.loader.plan.exec.internal.AliasResolutionContextImpl in project hibernate-orm by hibernate.

the class LoadPlanBuilderTest method testCollectionInitializerCase.

@Test
public void testCollectionInitializerCase() {
    CollectionPersister cp = sessionFactory().getCollectionPersister(Poster.class.getName() + ".messages");
    FetchStyleLoadPlanBuildingAssociationVisitationStrategy strategy = new FetchStyleLoadPlanBuildingAssociationVisitationStrategy(sessionFactory(), LoadQueryInfluencers.NONE, LockMode.NONE);
    LoadPlan plan = MetamodelDrivenLoadPlanBuilder.buildRootCollectionLoadPlan(strategy, cp);
    assertFalse(plan.hasAnyScalarReturns());
    assertEquals(1, plan.getReturns().size());
    Return rtn = plan.getReturns().get(0);
    CollectionReturn collectionReturn = ExtraAssertions.assertTyping(CollectionReturn.class, rtn);
    assertNotNull(collectionReturn.getElementGraph());
    assertNotNull(collectionReturn.getElementGraph().getFetches());
    // the collection Message elements are fetched, but Message.poster is not fetched
    // (because that collection is owned by that Poster)
    assertEquals(0, collectionReturn.getElementGraph().getFetches().length);
    EntityReference entityReference = ExtraAssertions.assertTyping(EntityReference.class, collectionReturn.getElementGraph());
    assertNotNull(entityReference.getFetches());
    assertEquals(0, entityReference.getFetches().length);
    LoadPlanTreePrinter.INSTANCE.logTree(plan, new AliasResolutionContextImpl(sessionFactory()));
