std::experimental::reflect::ObjectSequence(3) | C++ Standard Libary | std::experimental::reflect::ObjectSequence(3) |
NAME¶
std::experimental::reflect::ObjectSequence - std::experimental::reflect::ObjectSequence
Synopsis¶
Defined in header <experimental/reflect>
template< class T > (reflection TS)
concept ObjectSequence = Object<T> && /* see below */;
The ObjectSequence concept is satisfied by meta-object sequence types.
A meta-object sequence type is a meta-object type that is obtained from a
meta-object operation that generates a sequence, e.g. get_data_members. Each
element
of a meta-object sequence type is a meta-object type.
Example¶
// Run this code
#include<cmath>
#include<experimental/reflect>
#include<tuple>
#include<type_traits>
namespace reflect = std::experimental::reflect;
template<reflect::Typed... Ms>
using tuple_from_seq_t = std::tuple<reflect::get_reflected_type_t<
reflect::get_type_t<Ms>>...>;
template<reflect::Record T>
using collect_tuple = reflect::unpack_sequence_t<
tuple_from_seq_t,
reflect::get_data_members_t<T>>;
int main()
{
static_assert(reflect::ObjectSequence<
reflect::get_data_members<reflexpr(std::div_t)>>, "");
static_assert(std::is_same<collect_tuple<reflexpr(std::div_t)>,
std::tuple<int, int>>::value, "");
}
