Detailed Description

template<typename T>
struct has_max_prop_nn< T, typename Void< decltype(T::max_prop)>::type >

has_max_prop check if a type has defined a member max_prop

Example

 
        int val = has_max_prop_nn<test_has_max_prop>::value;
        BOOST_REQUIRE_EQUAL(val, true);
        val = has_max_prop_nn<test_has_no_max_prop>::value;
        BOOST_REQUIRE_EQUAL(val, false);
 
 
        val = has_max_prop<max_prop_vector_test, has_value_type_ofp<max_prop_vector_test>::value>::value;
        BOOST_REQUIRE_EQUAL(val, true);
        val = has_max_prop<max_prop_vector_test, has_value_type_ofp<max_prop_vector_test>::value>::number;
#ifndef SE_CLASS3
        BOOST_REQUIRE_EQUAL(val, 3);
#endif
 

return true if T::value_type::max_prop is a valid type
