 * $Log: AbstractStringValidator.hpp,v $
 * Revision 1.13  2004/01/29 11:51:22  cargilld
 * Code cleanup changes to get rid of various compiler diagnostic messages.
 *
 * Revision 1.12  2003/12/31 10:38:00  amassari
 * Made virtual function checkAdditionalFacet 'const', so that it matches the declaration in a derived class
 *
 * Revision 1.11  2003/12/17 00:18:38  cargilld
 * Update to memory management so that the static memory manager (one used to call Initialize) is only for static data.
 *
 * Revision 1.10  2003/11/12 20:32:03  peiyongz
 * Statless Grammar: ValidationContext
 *
 * Revision 1.9  2003/09/29 21:47:35  peiyongz
 * Implementation of Serialization/Deserialization
 *
 * Revision 1.8  2003/05/15 18:53:26  knoaman
 * Partial implementation of the configurable memory manager.
 *
 * Revision 1.7  2003/01/27 19:24:17  peiyongz
 * normalize Base64 data before checking against enumeration.
 *
 * Revision 1.6  2003/01/24 23:18:34  peiyongz
 * normalizeEnumeration() added to remove optional ws in Base64 data.
 *
 * Revision 1.5  2002/12/18 14:17:55  gareth
 * Fix to bug #13438. When you eant a vector that calls delete[] on its members you should use RefArrayVectorOf.
 *
 * Revision 1.4  2002/11/04 14:53:27  tng
 * C++ Namespace Support.
 *
 * Revision 1.3  2002/10/18 16:52:14  peiyongz
 * Patch to Bug#13640: Getter methods not public in
 *                                    DecimalDatatypeValidator

 *
 * Revision 1.7  2001/11/15 16:08:15  peiyongz
 * checkContent() made virtual to allow ListDTV participate in the building of
 * its own (in AbstractStringValidator's init())
 *
 * Revision 1.6  2001/10/11 19:32:12  peiyongz
 * Allow derived to overwrite inheritFacet()
 *
 * Revision 1.5  2001/10/09 21:00:54  peiyongz
 * . init() take 1 arg,
 * . make inspectFacetBase() virtual to allow ListDTV provide its own method,
 * . reorganize init() into assignFacet(), inspectFacet(), inspectFacetBase() and
 * inheritFacet() to improve mantainability.
 * . macro to simplify code
 * . save get***() to temp vars
 *
 * Revision 1.4  2001/09/27 13:51:25  peiyongz
 * DTV Reorganization: ctor/init created to be used by derived class
 *
 * Revision 1.3  2001/09/24 15:30:16  peiyongz
 * DTV Reorganization: init() to be invoked from derived class' ctor to allow
 *        correct resolution of virtual methods like assignAdditionalFacet(),
 *        inheritAdditionalFacet(), etc.
 *
 * Revision 1.2  2001/09/19 18:48:27  peiyongz
 * DTV reorganization:getLength() added, move inline to class declaration to avoid inline
