Yes, there shouldn't be a problem doing this. Are you having problems
doing it?
You can also use a DOM_Node as a key in an STL map, with a few
"enhancements." Here's how we do it in Xalan-C++:
class XercesDOM_NodeHack : public DOM_Node
{
public:
XercesDOM_NodeHack(const DOM_Node& theNode) :
DOM_Node(theNode)
{
}
XercesDOM_NodeHack(NodeImpl* theImpl = 0) :
DOM_Node(theImpl)
{
}
~XercesDOM_NodeHack()
{
}
NodeImpl*
getImpl() const
{
return fImpl;
}
static NodeImpl*
getImpl(const DOM_Node& theNode)
{
#if defined(XALAN_OLD_STYLE_CASTS)
return ((const XercesDOM_NodeHack&)theNode).getImpl();
#else
return static_cast<const XercesDOM_NodeHack&>(theNode).getImpl
();
#endif
}
};
inline bool
operator<(
const DOM_Node& theLHS,
const DOM_Node& theRHS)
{
#if !defined(XALAN_NO_NAMESPACES)
using std::less;
#endif
return less<NodeImpl*, NodeImpl*>()(
XercesDOM_NodeHack::getImpl(theLHS),
XercesDOM_NodeHack::getImpl(theRHS));
}
Of course if asked, I'll deny I _ever_ wrote this code ;-) And if you do
_anything_ with the implementation pointer, then you're on your own.
