I'd like to use the formal argument to a template as the qualifier of a
qualified typename within the template. This doesn't work in CodeWarrior
8, it does work in VC++ 4.0, and I can't tell from ARM whether or not it
*should* work.
Here's a more specific example:
template <class OBJECT>
class OrderedCollection {
typedef void (OBJECT::*memberMapper)(void);
.
.
.
};
I would like the typedef 'memberMapper' to refer to pointers to member
functions (of no arguments and returning no value) of whatever class is
specified in a given instantiation of the template.
For instance, if X and Y are classes, I would expect memberMapper in
OrderedCollection<X> to be:
void (X::*memberMapper)(void)
and memberMapper in OrderedCollection<Y> to be:
void (Y::*memberMapper)(void)
Should this work or not? If not, why not? If so -- this is a bug in CW8.
