| Criteria API has provided an alternative means to string-based JPQL to |
| execute a query. However, JPA 2.0 specification has not explicitly specified |
| any equivalence between a dynamically constructed CriteriaQuery and |
| a JPQL string. OpenJPA provides a mechanism to convert a CriteriaQuery to |
| an equivalent JPQL query string via the extended OpenJPACriteriaQuery API. |
