template <class a, class b>
class c
{
private:
b defaultVal;
public:
std::map<a,b> mymap;
const b &func(a idx)
{
typename std::map<a,b>::iterator it(mymap.find(idx));
if (it!=mymap.end())
return it->second;
else
return defaultVal;
}
};
The compiler is not sure std::map<a,b>::iterator is a typename or a value.
