- * $Log: weakmap.inl,v $
- * Revision 1000.0 2003/10/29 15:33:24 gouriano
- * PRODUCTION: IMPORTED [ORIGINAL] Dev-tree R1.7
- *
- * Revision 1.7 2001/05/17 15:01:19 lavr
- * Typos corrected
- *
- * Revision 1.6 2001/01/05 20:08:54 vasilche
- * Added util directory for various algorithms and utility classes.
- *
- * Revision 1.5 2000/12/26 22:23:46 vasilche
- * Fixed errors of compilation on Mac.
- *
- * Revision 1.4 2000/10/20 15:51:28 vasilche
- * Fixed data error processing.
- * Added interface for constructing container objects directly into output stream.
- * object.hpp, object.inl and object.cpp were split to
- * objectinfo.*, objecttype.*, objectiter.* and objectio.*.
- *
- * Revision 1.3 2000/10/13 16:28:34 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 1.2 2000/09/29 20:14:30 vasilche
- * Fixed name conflict (map).
- *
- * Revision 1.1 2000/09/29 16:18:16 vasilche
- * Fixed binary format encoding/decoding on 64 bit compulers.
- * Implemented CWeakMap<> for automatic cleaning map entries.
- * Added cleaning local hooks via CWeakMap<>.
- * Renamed ReadTypeName -> ReadFileHeader, ENoTypeName -> ENoFileHeader.
- * Added some user interface methods to CObjectIStream, CObjectOStream and
- * CObjectStreamCopier.
