C++ "if then else" template substitution
- by duli
I would like to declare a template as follows:
template <typename T>
{
if objects of class T have method foo(), then
const int k=1
else
if class has a static const int L then
const int k=L
else
const int k=0;
}
How can I do this? In general, I would like a mechanism for setting static consts
based on properties of T (or typedef defined inside T).
