 /**

  * A SqlSelectStatement sublclass that is aware of a special {@link SuffixableQueryByCriteria} Criteria

  * class and will append a suffix specified by that class of criteria to the generated SQL statement.

  * This is a hack to introduce select-for-update functionality into OJB so the same ORM/Criteria abstractions

  * can be retained for select-for-update queries.  Select for update appears to have been added in the OJB

  * source repository, so maybe a forthcoming release will include this functionality and these kludges can be

  * removed.
