Detailed Description

template<typename Functor>
class cohtml::FunctorTraits< Functor >

Provides information about function objects.

Provides the following information about a function object

  • return type
  • arity
  • whether it is pointer to member function
  • the type of each argument (with const and references stripped)

To support your custom handlers use the following pattern:

class SquareCalculator
void double operator()(double r) const
return r * r;
// provide support for SquareCalculator to FunctorTraits
namespace Coherent
namespace cohtml
template <>
struct FunctorTraits<SquareCalculator>
: FunctorTraits<double (double)>
