- * Revision 1000.1 2004/06/01 19:40:05 gouriano
- * PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.8
- *
- * Revision 1.8 2004/05/17 21:03:02 gorelenk
- * Added include of PCH ncbi_pch.hpp
- *
- * Revision 1.7 2002/11/04 21:29:20 grichenk
- * Fixed usage of const CRef<> and CRef<> constructor
- *
- * Revision 1.6 2001/01/05 20:10:50 vasilche
- * CByteSource, CIStrBuffer, COStrBuffer, CLightString, CChecksum, CWeakMap
- * were moved to util.
- *
- * Revision 1.5 2000/09/18 20:00:21 vasilche
- * Separated CVariantInfo and CMemberInfo.
- * Implemented copy hooks.
- * All hooks now are stored in CTypeInfo/CMemberInfo/CVariantInfo.
- * Most type specific functions now are implemented via function pointers instead of virtual functions.
- *
- * Revision 1.4 2000/08/15 19:44:47 vasilche
- * Added Read/Write hooks:
- * CReadObjectHook/CWriteObjectHook for objects of specified type.
- * CReadClassMemberHook/CWriteClassMemberHook for specified members.
- * CReadChoiceVariantHook/CWriteChoiceVariant for specified choice variants.
- * CReadContainerElementHook/CWriteContainerElementsHook for containers.
- *
- * Revision 1.3 2000/06/16 16:31:19 vasilche
- * Changed implementation of choices and classes info to allow use of the same classes in generated and user written classes.
- *
- * Revision 1.2 2000/05/03 14:38:13 vasilche
- * SERIAL: added support for delayed reading to generated classes.
- * DATATOOL: added code generation for delayed reading.
- *
- * Revision 1.1 2000/04/28 16:58:12 vasilche
- * Added classes CByteSource and CByteSourceReader for generic reading.
- * Added delayed reading of choice variants.
