| * 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> |
