- * Revision 1.4 2001/10/15 20:18:32 knoaman
- * Fix for bug 4177.
- *
- * Revision 1.3 2001/05/11 13:26:52 tng
- * Copyright update.
- *
- * Revision 1.2 2001/05/03 18:18:02 knoaman
- * Some design changes:
- * o Changed the TokenFactory from a single static instance, to a
- * normal class. 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.
