| * Revision 1.11 2001/10/25 21:47:14 peiyongz |
| * Replace XMLDeleterFor with XMLRegisterCleanup |
| * |
| * Revision 1.10 2001/10/23 23:04:38 peiyongz |
| * [Bug#880] patch to PlatformUtils:init()/term() and related. from Mark Weaver |
| * |
| * Revision 1.9 2000/05/09 00:22:31 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 1.8 2000/04/27 02:52:42 lehors |
| * global reorganization similar to what I've done in Java, |
| * nodes now are much smaller. |
| * The main changes are: |
| * renamed NodeContainer to ParentNode, |
| * introduced ChildNode and ChildAndParentNode, |
| * all the boolean attributes have been changed to bit flags, |
| * ownerDocument is no longer an attribute of NodeImpl, only Parent nodes have |
| * it, leave nodes rely on their parent to get it, or get it from ownerNode when |
| * they do not have a parent, |
| * parent Nodes no longer have a direct pointer to the last child |
| * instead the last child is stored as the previous sibling of |
| * the first child. |
| * I also added support for importing a DocumentType as it's done in Java, |
| * and got the importNode mechanism back in sync with Java as well. |
| * |
| * Here are the most significant changes in size: |
| * ElementImpl 52 -> 48 |
| * TextImpl 44 -> 32 |
| * AttrImpl 52 -> 36 |
| * |
| * Revision 1.7 2000/03/02 19:53:54 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 2000/02/10 23:35:10 andyh |
| * Update DOM_DOMImplementation::CreateDocumentType and |
| * DOM_DocumentType to match latest from W3C |
| * |
| * Revision 1.5 2000/02/06 07:47:28 rahulj |
| * Year 2K copyright swat. |
| * |
| * Revision 1.4 2000/01/19 21:39:19 andyh |
| * DOM L2, fix problems with new style createDocument. |
| * |
| * Revision 1.3 2000/01/05 01:16:07 andyh |
| * DOM Level 2 core, namespace support added. |
| * |
| * Revision 1.2 1999/11/30 21:16:25 roddey |
| * Changes to add the transcode() method to DOMString, which returns a transcoded |
| * version (to local code page) of the DOM string contents. And I changed all of the |
| * exception 'throw by pointer' to 'throw by value' style. |
| * |
| * Revision 1.1.1.1 1999/11/09 01:08:56 twl |
| * Initial checkin |
| * |
| * Revision 1.3 1999/11/08 20:44:15 rahul |
| * Swat for adding in Product name and CVS comment log variable. |
