- * $Log: DOMStringImpl.hpp,v $
- * Revision 1.8 2000/05/09 00:22:30 andyh
- * Memory Cleanup. XMLPlatformUtils::Terminate() deletes all lazily
- * allocated memory; memory leak checking tools will no longer report
- * that leaks exist. (DOM GetElementsByTagID temporarily removed
- * as part of this.)
- *
- * Revision 1.7 2000/03/02 19:53:52 roddey
- * This checkin includes many changes done while waiting for the
- * 1.1.0 code to be finished. I can't list them all here, but a list is
- * available elsewhere.
- *
- * Revision 1.6 2000/02/24 20:11:27 abagchi
- * Swat for removing Log from API docs
- *
- * Revision 1.5 2000/02/06 07:47:27 rahulj
- * Year 2K copyright swat.
- *
- * Revision 1.4 2000/02/04 05:46:31 andyh
- * Change offsets and lengths form signed to unsigned
- *
- * Revision 1.3 2000/01/29 00:39:08 andyh
- * Redo synchronization in DOMStringHandle allocator. There
- * was a bug in the use of Compare and Swap. Switched to mutexes.
- *
- * Changed a few plain deletes to delete [].
- *
- * Revision 1.2 2000/01/12 19:55:14 aruna1
- * Included header for size_t
- *
- * Revision 1.1 2000/01/05 22:16:26 robweir
- * Move DOMString implementation class declarations into a new
- * file: DOMStringImpl.hpp. Include this header in DOMString.hpp
- * for XML_DEBUG builds so the underlying character array will be
- * visible in the debugger. <robert_weir@lotus.com>
