I would like to conditionally compile a member of a class based on it's class template parameter. I have convenience functions that only make sense to the compiler in certain conditions so I'd like for the compiler to skip them if I can programmatically determine when this is so.
// T is a mathematical type
template <typename T>
class Foo {
public:
// when zero is not clearly defined
void bar(T a, T b, T zero) {
}
// only makes sense if 0 can be cast to T
// will fail otherwise
void bar(T a, T b) {
bar(a, b, 0);
}
}
- I am using VS2012, so sadly, no default member template parameters. :(
What is the best way to achieve what I want?
