Re: [Boost-users] [TypeTraits] Using has_call

2013/4/24 Robert Jones <robertgbjones@gmail.com>

Hi Folks

I know has_call is not yet part of Boost, but using the implementation from

https://github.com/jamboree/boost.has_call

with this code

#include "boost/type_traits/has_call.hpp" #include <cassert>

template<typename Sig, typename F> bool HasCall(F const&) { return boost::has_call<F, Sig>::value; }

void DefaultVal(int) {}

int main() { assert(HasCall<boost::dont_care(int)>(DefaultVal)); }

fails to compile for me, with a template instantiation ambiguity error. Seems the error is triggered by the use of boost::dont_care.

Any ideas?

Replied in another thread, just fixed it. HTH
