public void handlePropertyBeingDereferenced(Type propertySource, String propertyName) {
    if (getQueryableCollection() != null && CollectionProperties.isCollectionProperty(propertyName)) {
        // propertyName refers to something like collection.size...
        return;

            }
        } catch (QueryException ignore) {
        // ignore it; the incoming property could not be found so we
        // cannot be sure what to do here.  At the very least, the
        // safest is to simply not apply any dereference toggling...
        }

Example 3 with Queryable

use of org.hibernate.persister.entity.Queryable in project hibernate-orm by hibernate.

    if (parentFromClause != null) {
        // Look up class name using the first identifier in the path.
        final String pathAlias = PathHelper.getAlias(path);
        final FromElement parentFromElement = parentFromClause.getFromElement(pathAlias);

    // Add to the query spaces.
    fromClause.getWalker().addQuerySpaces(entityPersister.getQuerySpaces());
    return elem;
