스레드 간에 연관된 Future로 값 또는 오류를 전달하기 위한 비동기 채널을 제공합니다.

ara::core::Promise 클래스는 스레드 간에 값, 오류 또는 결과를 공유 상태(shared state)로 전송하기 위한 비동기 쓰기 엔드포인트 역할을 합니다 [SWS_CORE_00341]. 읽기 액세스는 정확히 한 번만 검색할 수 있는 Future을(를) 통해 수행되며, 이는 결과가 제공될 때 해제됩니다 [SWS_CORE_00344]. 이 클래스는 복사할 수 없으므로 이동 시맨틱을 통해 상태가 엄격하게 고유 소유권으로 유지되며, 결과를 중복 설정하거나 Future를 중복 검색하면 표준화된 위반이 발생합니다.

컨텍스트

ara::core::Promise 클래스는 C++ 표준에서 알려진 std::promise 개념의 Adaptive Platform 전용 구현체를 나타냅니다. 헤더 ara/core/future.h에 템플릿 Promise<T, E = ErrorCode>(으)로 정의되어 있으며 공유 상태(shared state)의 비동기 쓰기 엔드포인트 역할을 합니다. 이 채널을 통해 생산자는 스레드 간에 계산된 출력 값, 오류 또는 집약된 ara::core::Result을(를) 전달합니다. 연관된 수신자 측은 인스턴스 메서드 get_future을(를) 통해 조회되는 연관된 ara::core::Future을(를) 통해 결과에 액세스합니다 [SWS_CORE_00344]. 주로 예외에 의존하는 표준 C++ 메커니즘과 달리, AUTOSAR Adaptive는 오류 유형화 패러다임을 정립합니다: 오류 유형 E이(가) ara::core::ErrorCode과(와) 다르게 선택되는 경우, 사양에 따라 컴파일 오류가 발생합니다.

수명 주기

인스턴스는 std::promise의 해당 생성자처럼 동작하고 스레드 안전하며 새로운 공유 상태를 설정하는 매개변수 없는 기본 생성자를 통해 통상적으로 생성됩니다 [SWS_CORE_00341]. 이 상태에 대한 명확한 소유권을 보장하기 위해 복사 작업은 완전히 금지됩니다. 복사 생성자 [SWS_CORE_00350]와 복사 할당 연산자 [SWS_CORE_00351]은 모두 삭제(delete)(으)로 선언되어 있습니다.

그러나 이 클래스는 이동 시맨틱(Move)을 지원합니다. 이동 생성자는 소스 인스턴스 [SWS_CORE_00342]의 공유 상태를 인계받습니다. 이동 할당의 경우, 대상 인스턴스는 기존의 공유 상태를 포기하고 스왑 작업과 유사하게 전달받은 객체의 상태를 인계받습니다 [SWS_CORE_00343]. 또한 swap 메서드를 통해 내부 상태를 다른 인스턴스와 교환할 수 있습니다 [SWS_CORE_00352]. 소멸자를 통한 소멸 시, 아직 유지되고 있는 공유 상태는 해제되거나 종료됩니다 [SWS_CORE_00349]. 기본 생성자는 스레드 안전하게 설계된 반면 [SWS_CORE_00341], 이동 작업, 할당, 스왑 및 소멸은 스레드 안전하지 않습니다([SWS_CORE_00342], [SWS_CORE_00343], [SWS_CORE_00352], [SWS_CORE_00349]).

사용 경로

일반적인 제공 흐름은 다음 단계들로 구성됩니다:

생성: 생산자가 ara::core::Promise<T, E>을(를) 인스턴스화합니다 [SWS_CORE_00341].
Future 조회: 비동기 처리를 시작하기 전에 생산자는 get_future()을(를) 호출합니다 [SWS_CORE_00344]. Promise당 단 하나의 연관된 Future만 허용되므로, 이 호출은 정확히 한 번만 수행되어야 합니다. 반환된 Future은(는) 소비 스레드로 전달됩니다.
결과 설정: 비동기 작업이 완료된 후 생산자는 결과를 공유 상태로 전송하고 이를 ready 상태로 전환합니다. 이를 위해 복사 및 이동 작업을 위한 스레드 안전한 오버로드가 각각 제공됩니다:
- 성공적인 값: set_value 호출([SWS_CORE_00345], [SWS_CORE_00346]).
- 오류 상태: SetError 호출([SWS_CORE_00353], [SWS_CORE_00354]).
- 결합된 결과: SetResult 호출([SWS_CORE_00355], [SWS_CORE_00356]).

시퀀스 다이어그램: 생산자, Promise, Shared State 및 소비자 간의 호출 및 동기화 순서. 출처: [SWS_CORE_00341], [SWS_CORE_00344], [SWS_CORE_00345], [SWS_CORE_00353], [SWS_CORE_00355]

오류 시나리오

사양은 공유 상태와의 모든 상호작용에 대해 엄격한 사전 조건을 정의하며, 이를 준수하지 않을 경우 표준화된 위반(Violations)이 발생합니다:

Future의 다중 조회: 동일한 공유 상태에 대해 get_future()이(가) 두 번 이상 호출되면 위반 IsoStdFutureErrcFutureAlreadyRetrievedViolation이(가) 발생합니다 [SWS_CORE_00344].
Shared State 누락: 호출된 인스턴스에 공유 상태가 없는 경우(예: 이동 작업 수행 후) get_future()은(는) IsoStdFutureErrcNoStateViolation을(를) 유발합니다 [SWS_CORE_00344]. 이 경우 set_value, SetError 및 SetResult 메서드는 위반 PromiseNoSharedStateToSetViolation을(를) 트리거합니다([SWS_CORE_00345], [SWS_CORE_00353], [SWS_CORE_00355]).
이미 충족된 상태: 공유 상태에 이미 값, 오류 또는 결과가 채워져 있는 경우, set_value([SWS_CORE_00345], [SWS_CORE_00346]), SetError([SWS_CORE_00353], [SWS_CORE_00354]) 또는 SetResult([SWS_CORE_00355], [SWS_CORE_00356])을(를) 다시 호출할 때마다 위반 IsoStdFutureErrcPromiseAlreadySatisfiedViolation이(가) 발생합니다.
예외 안전성: set_value, SetError 및 SetResult 메서드는 조건부 예외 안전성(conditionally exception safe)을 가집니다. 타입 T 및 E의 생성자가 nothrow(으)로 선언되어 있는 경우 예외를 발생시키지 않습니다([SWS_CORE_00345], [SWS_CORE_00353], [SWS_CORE_00355]).

해석: 사전 값 할당 없이 인스턴스 소멸 시 공유 상태를 포기하는 것([SWS_CORE_00349])은 std::promise의 표준 C++ 동작과 유사하게, 연관된 Future이(가) 읽기 시도 시 해당 오류 이벤트를 등록하도록 할 것으로 보입니다. 질문 Q-fd013bb17a591af9 (열림)
