 /**

  * SqlGeneratorDefaultImpl subclass that replaced the vanilla SqlSelectStatement implementation

  * with a new {@link SuffixedSqlSelectStatement} that is {@link SuffixableQueryByCriteria} - aware.

  * This class needs to be specified as the SqlGenerator implementation in the OJB properties, to replace

  * the SqlGeneratorDefaultImpl.

  * 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.

  * @see SuffixedSqlSelectStatement
