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
{
    public:
        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)>
        {
        };
    }
}
