templates, typedefs and inheritance
I find templates and inheritance confusing, something about qualified/unqualified lookups. Mostly I manage, but here is something that's troubling me:
I have base classes that depend on template parameters, and that contain convenient typedef's that may or may not also depend on the template parameters. When I inherit from the base classes, the typedefs are generally _not_ visible. Since I don't want to type e.g.
(or worse) for every "mytypedef", I make a new typedef
typedef BaseClass<typename1, typename2>::mytypedef mytypedef;
in the derived class. Obviously this works, but it feels a bit dirty. The problem now is that I'm starting to use Doxygen and Doxygen dutifully reports all the different typedefs, which looks ugly. With variables I can do e.g.
using BaseClass<typename1, typename2>::myvar
in the derived class. Can you do something similar with typedef's instead of declaring new ones all the time?
