Each RegularExpression object will have its own *    instance of TokenFactory, and that instance will be passed to *    other classes that need to use a TokenFactory to create Token *    objects (with the exception of RangeTokenMap). * o Added a new class RangeTokenMap to map a the different ranges *    in a given category to a specific RangeFactory object. In the old *    design RangeFactory had dual functionality (act as a Map, and as *    a factory for creating RangeToken(s)). The RangeTokenMap will *    have its own copy of the TokenFactory. There will be only one *    instance of the RangeTokenMap class, and that instance will be *    lazily deleted when XPlatformUtils::Terminate is called. * */// ---------------------------------------------------------------------------//  Includes// ---------------------------------------------------------------------------#include <xercesc/util/regx/RangeTokenMap.hpp>#include <xercesc/util/regx/RangeToken.hpp>#include <xercesc/util/regx/RegxDefs.hpp>#include <xercesc/util/regx/TokenFactory.hpp>#include <xercesc/util/regx/RangeFactory.hpp>#include <xercesc/util/PlatformUtils.hpp>#include <xercesc/util/XMLExceptMsgs.hpp>#include <xercesc/util/XMLRegisterCleanup.hpp>#include <xercesc/util/StringPool.hpp>XERCES_CPP_NAMESPACE_BEGIN// ---------------------------------------------------------------------------//  Local static data// ---------------------------------------------------------------------------static XMLMutex* sRangeTokMapMutex = 0;static XMLRegisterCleanup rangeTokMapRegistryCleanup;static XMLRegisterCleanup rangeTokMapInstanceCleanup;// ---------------------------------------------------------------------------//  Local, static functions// ---------------------------------------------------------------------------static void reinitRangeTokMapMutex(){    delete sRangeTokMapMutex;
