Detailed Description

template<typename T>
struct has_data< T, typename Void< decltype(T::data)>::type >

has_data check if a type has defined a member data

Example

        struct test_has_data
        {
            float data;
        };

        struct test_no_has_data
        {
        };

        int val = has_data<test_has_data>::value;
        BOOST_REQUIRE_EQUAL(val, true);
        val = has_data<test_no_has_data>::value;
        BOOST_REQUIRE_EQUAL(val, false);

return true if T::type is a valid type
