std::promise
template < class R, class Alloc >
struct uses_allocator < std:: promise < R > , Alloc > : std:: true_type { } ;
(C++11 이후)

std::uses_allocator 타입 트레이트의 std::promise 에 대한 특수화를 제공합니다.

목차

상속받음 std:: integral_constant

멤버 상수

value
[static]
true
(public static member constant)

멤버 함수

operator bool
객체를 bool 로 변환, value 반환
(public member function)
operator()
(C++14)
value 반환
(public member function)

멤버 타입

타입 정의
value_type bool
type std:: integral_constant < bool , value >

참고 항목

(C++11)
지정된 타입이 uses-allocator 생성 방식을 지원하는지 확인합니다
