- *
- * Revision 1.10 2004/05/17 21:03:02 gorelenk
- * Added include of PCH ncbi_pch.hpp
- *
- * Revision 1.9 2004/01/05 14:25:20 gouriano
- * Added possibility to set serialization hooks by stack path
- *
- * Revision 1.8 2003/08/19 18:32:38 vasilche
- * Optimized reading and writing strings.
- * Avoid string reallocation when checking char values.
- * Try to reuse old string data when string reference counting is not working.
- *
- * Revision 1.7 2003/07/29 20:36:48 vasilche
- * Fixed warnings on Windows.
- *
- * Revision 1.6 2003/07/29 18:59:21 vasilche
- * Fixed compilation errors.
- *
- * Revision 1.5 2003/07/29 18:47:47 vasilche
- * Fixed thread safeness of object stream hooks.
- *
- * Revision 1.4 2002/11/04 21:29:20 grichenk
- * Fixed usage of const CRef<> and CRef<> constructor
- *
- * Revision 1.3 2001/01/05 20:10:50 vasilche
- * CByteSource, CIStrBuffer, COStrBuffer, CLightString, CChecksum, CWeakMap
- * were moved to util.
- *
- * Revision 1.2 2000/10/13 16:28:39 vasilche
- * Reduced header dependency.
- * Avoid use of templates with virtual methods.
- * Reduced amount of different maps used.
- * All this lead to smaller compiled code size (libraries and programs).
- *
- * Revision 1.1 2000/10/03 17:22:42 vasilche
- * Reduced header dependency.
- * Reduced size of debug libraries on WorkShop by 3 times.
- * Fixed tag allocation for parent classes.
- * Fixed CObject allocation/deallocation in streams.
- * Moved instantiation of several templates in separate source file.
