025/**
026 * A SqlSelectStatement sublclass that is aware of a special {@link SuffixableQueryByCriteria} Criteria
027 * class and will append a suffix specified by that class of criteria to the generated SQL statement.
028 * This is a hack to introduce select-for-update functionality into OJB so the same ORM/Criteria abstractions
029 * can be retained for select-for-update queries.  Select for update appears to have been added in the OJB
030 * source repository, so maybe a forthcoming release will include this functionality and these kludges can be
031 * removed.
