            for (ImplicitParameterBinding implicitParameter : implicitParameterBindings) {
                map.put(implicitParameter.getParameterName(), implicitParameter.getJavaType());
            }

Example 3 with QueryImplementor

use of org.hibernate.query.spi.QueryImplementor in project hibernate-orm by hibernate.

the class SessionImpl method createQuery.

@Override
@SuppressWarnings("unchecked")
public <T> QueryImplementor<T> createQuery(String jpaqlString, Class<T> resultClass, Selection selection, QueryOptions queryOptions) {
    try {
        final QueryImplementor query = createQuery(jpaqlString);

            }
        }
        // determine if we need a result transformer
        List tupleElements = Tuple.class.equals(resultClass) ? ((CompoundSelectionImpl<Tuple>) selection).getCompoundSelectionItems() : null;
        if (queryOptions.getValueHandlers() != null || tupleElements != null) {
            query.setResultTransformer(new CriteriaQueryTupleTransformer(queryOptions.getValueHandlers(), tupleElements));
        }
