Examples with ListJoin jakarta.persistence.criteria.ListJoin used on opensource projects

Example 1 with ListJoin

use of jakarta.persistence.criteria.ListJoin in project hibernate-orm by hibernate.

the class AbstractQueryCacheResultTransformerTest method testListElementsProjectionList.

@Test
public void testListElementsProjectionList(SessionFactoryScope scope) throws Exception {
    CriteriaExecutor criteriaExecutor = new CriteriaExecutor() {

        @Override
        protected ResultTransformer getResultTransformer() {
            return null;
        }

        @Override
        protected JpaCriteriaQuery getCriteria(Session s) {
            CriteriaBuilder builder = s.getCriteriaBuilder();
            JpaCriteriaQuery criteria = (JpaCriteriaQuery) builder.createQuery();
            Root<Enrolment> root = criteria.from(Student.class);
            final ListJoin<Object, Object> secretCodes = root.joinList("secretCodes");
            criteria.select(secretCodes);
            return criteria;
        }
    };
    HqlExecutor hqlExecutor = new HqlExecutor() {

        @Override
        public Query getQuery(Session s) {
            return s.createQuery("select elements(s.secretCodes) from Student s");
        }
    };
    ResultChecker checker = results -> {
        List resultList = (List) results;
        assertEquals(3, resultList.size());
        assertTrue(resultList.contains(yogiExpected.getSecretCodes().get(0)));
        assertTrue(resultList.contains(shermanExpected.getSecretCodes().get(0)));
        assertTrue(resultList.contains(shermanExpected.getSecretCodes().get(1)));
    };
    runTest(hqlExecutor, criteriaExecutor, checker, false, scope);
}

Example 2 with ListJoin

use of jakarta.persistence.criteria.ListJoin in project eclipselink by eclipse-ee4j.

the class CriteriaBuilderImpl method treat.

@Override
public <X, T, E extends T> ListJoin<X, E> treat(ListJoin<X, T> join, Class<E> type) {
    ListJoinImpl parentJoin = (ListJoinImpl) join;
    ListJoin joinImpl = null;
    if (join instanceof BasicListJoinImpl) {
        joinImpl = new BasicListJoinImpl<X, E>(parentJoin, this.metamodel, type, parentJoin.currentNode.treat(type), parentJoin.getModel(), parentJoin.getJoinType());
    } else {
        joinImpl = new ListJoinImpl<X, E>((Path) join, this.metamodel.managedType(type), this.metamodel, type, parentJoin.currentNode.treat(type), parentJoin.getModel(), parentJoin.getJoinType());
    }
    parentJoin.joins.add(joinImpl);
    ((FromImpl) joinImpl).isJoin = parentJoin.isJoin;
    parentJoin.isJoin = false;
    return joinImpl;
}

Example 3 with ListJoin

use of jakarta.persistence.criteria.ListJoin in project hibernate-orm by hibernate.

the class HHH14916Test method testJoinOnFetchNoExceptionThrow.

@Test
public void testJoinOnFetchNoExceptionThrow(EntityManagerFactoryScope scope) {
    scope.inTransaction(entityManager -> {
        final CriteriaBuilder builder = entityManager.getCriteriaBuilder();
        final CriteriaQuery<Author> query = builder.createQuery(Author.class);
        final Root<Author> root = query.from(Author.class);
        final ListJoin<Author, Book> authorBookJoin = (ListJoin) root.fetch("books", JoinType.LEFT);
        final ListJoin<Book, Chapter> bookChapterJoin = authorBookJoin.joinList("chapters", JoinType.LEFT);
        final Predicate finalPredicate = builder.equal(bookChapterJoin.get("name"), "Overview of HTTP");
        query.where(finalPredicate);
        Author author = entityManager.createQuery(query).getSingleResult();
        assertEquals("David Gourley", author.name);
        assertEquals("HTTP Definitive guide", author.books.get(0).name);
        assertEquals("Overview of HTTP", author.books.get(0).chapters.get(0).name);
    });
}
