Detailed Description

template<class Traits, int index, bool flag = (index < Traits::arity)>
struct senf::function_traits_arg_type< Traits, index, flag >

Get argument type from function traits.

function_traits_arg<Traits, index> will return the type of the index-th argument from Traits. If the function has no argument at that index, void is returned

typedef boost::function_traits<void (int, double)> traits;
BOOST_STATIC_ASSERT(( boost:is_same<
    senf::function_traits_arg_type< traits, 0 >::type,
    int
>::value ));
BOOST_STATIC_ASSERT(( boost::is_same<
    senf::function_traits_arg_type< traits, 2 >::type,
    void
>::value ));

    \tparam Traits \c boost::function_traits instantiation
    \tparam index 0 based argument index
