The following code:
#include <tuple>
template <typename M>
struct is_generative_model {
private:
template <typename Z> static auto test(int) -> decltype(
static_cast<std::tuple<size_t, double>
(Z::*)(size_t,size_t) const> (&Z::sampleOR),
static_cast<std::tuple<size_t,size_t, double>
(Z::*)(size_t,size_t) const> (&Z::sampleSOR),
std::true_type()
);
template <typename Z> static auto test(...) -> std::false_type;
public:
enum { value = std::is_same<decltype(test<M>(0)),std::true_type>::value
};
};
int main() {
return 0;
}
When compiled with:
g++ -std=c++11 main.cpp
Triggers the following error:
