[ http://issues.apache.org/jira/browse/XERCESC-783?page=all ]
Alberto Massari resolved XERCESC-783.
-------------------------------------
Resolution: Fixed
Assignee: (was: Xerces-C Developers Mailing List)
In Xerces 3.0, the DOMUserDataHandler::handle callback specifies 'dst' as a
non-const DOMNode
> DOMUserDataHandler<_TT>::handle -- dst argument is of type const DOMNode*
> -------------------------------------------------------------------------
>
> Key: XERCESC-783
> URL: http://issues.apache.org/jira/browse/XERCESC-783
> Project: Xerces-C++
> Issue Type: Bug
> Components: DOM
> Affects Versions: 2.1.0
> Environment: Operating System: All
> Platform: All
> Reporter: David Reitter
>
> A functional object with a 'handle' function needs to be specified when using
> the setUserData method to store arbitrary data along with a DOMNode.
> During operation NODE_CLONED, I change 'dst' as follows:
> dst->setUserData(key, new _TT( ( *(_TT *) data ) ), this);
> (_TT is the type of the data, as I have defined a template for that.)
> This operation is not legal (but compiles with GCC3.1, not with 2.95), because
> dst is defined to be "const DOMNode*".
> I don't know whether I'm supposed to do it that way, but if I am, this seems
> to
> me like a design bug.
> FIX:
> update definition of DOMUserDataHandler::handle.
> ps.:
> My workaround is a cast
> ((DOMNode*) dst)->setUserData(key, new _TT( ( *(_TT *) data ) ), this);
