Detailed Description
template<class D, class R = void>
struct Dune::Std::is_callable< D, R >
struct Dune::Std::is_callable< D, R >
Traits class to check if function is callable.
- Deprecated:
- Use std::is_invocable from <type_traits>
- Template Parameters

D Function descriptor R Return value
If D = F(Args...) this checks if F can be called with an argument list of type Args..., and if the return value can be converted to R. If R is void, any return type is accepted. The result is encoded by deriving from std::integral_constant<bool, result>.
If D is not of the form D = F(Args...) this class is not defined.
This implements std::is_callable as proposed in N4446 for C++17.
