Example 6 with GraphSemantic

use of org.hibernate.graph.GraphSemantic in project hibernate-orm by hibernate.

the class CriteriaEntityGraphTest method testSemanticsWithSubgraph.

@ParameterizedTest
@EnumSource(GraphSemantic.class)
void testSemanticsWithSubgraph(GraphSemantic graphSemantic) {
    scope.inTransaction(session -> {
        final RootGraphImplementor<Cat> eg = session.createEntityGraph(Cat.class);
        eg.addSubgraph("owner", Person.class);
        final SelectStatement sqlAst = buildSqlSelectAst(Cat.class, eg, graphSemantic, session);
        // Check the from-clause
        assertEntityValuedJoinedGroup(sqlAst, "owner", Person.class, this::assertPersonHomeAddressJoinedGroup);
        // Check the domain-result graph
        assertDomainResult(sqlAst, Cat.class, "owner", Person.class, entityFetch -> {
            if (graphSemantic == GraphSemantic.LOAD) {
                assertThat(entityFetch, instanceOf(EntityFetchJoinedImpl.class));
                final EntityResult entityResult = ((EntityFetchJoinedImpl) entityFetch).getEntityResult();
                final Map<String, Class<? extends Fetch>> fetchClassByAttributeName = entityResult.getFetches().stream().collect(Collectors.toMap(fetch -> fetch.getFetchedMapping().getPartName(), Fetch::getClass));
                final Map<String, Class<? extends Fetch>> expectedFetchClassByAttributeName = new HashMap<>();
                expectedFetchClassByAttributeName.put("pets", DelayedCollectionFetch.class);
                expectedFetchClassByAttributeName.put("homeAddress", EmbeddableFetchImpl.class);
                expectedFetchClassByAttributeName.put("company", EntityDelayedFetchImpl.class);
                assertThat(fetchClassByAttributeName, is(expectedFetchClassByAttributeName));
            }
        });
    });
}

Example 7 with GraphSemantic

use of org.hibernate.graph.GraphSemantic in project hibernate-reactive by hibernate.

the class ReactiveSessionImpl method reactiveInternalLoad.

@Override

    final EffectiveEntityGraph effectiveEntityGraph = getLoadQueryInfluencers().getEffectiveEntityGraph();
    final GraphSemantic semantic = effectiveEntityGraph.getSemantic();

    boolean clearedEffectiveGraph;
    if (semantic == null || graph.appliesTo(entityName)) {
        clearedEffectiveGraph = false;
    } else {
        // log.debug( "Clearing effective entity graph for subsequent-select" );
        clearedEffectiveGraph = true;
        effectiveEntityGraph.clear();
    }

    if (nullable) {
        type = LoadEventListener.INTERNAL_LOAD_NULLABLE;
    } else {
        type = eager ? LoadEventListener.INTERNAL_LOAD_EAGER : LoadEventListener.INTERNAL_LOAD_LAZY;
    }
    threadCheck();
    LoadEvent event = new LoadEvent(id, entityName, true, this, getReadOnlyFromLoadQueryInfluencers());
    return fireLoadNoChecks(event, type).thenApply(v -> {
        Object result = event.getResult();
        if (!nullable) {
            UnresolvableObjectException.throwIfNull(result, id, entityName);
        }
        return result;
    }).whenComplete((v, x) -> {
        if (clearedEffectiveGraph) {
            effectiveEntityGraph.applyGraph(graph, semantic);
