매개 변수
- connection
- DbConnection
연결입니다.
- eventData
- TransactionStartingEventData
연결 및 트랜잭션에 대한 컨텍스트 정보입니다.
- result
- InterceptionResult<DbTransaction>
있는 경우 현재 결과를 나타냅니다.
이전의 일부 인터셉터에서 를 호출SuppressWithResult(TResult)하여 true
실행을 억제한 경우 이 값은 로 설정됩니다HasResult.
이 값은 일반적으로이 메서드의 구현에 대 한 반환 값으로 사용 합니다.
- cancellationToken
- CancellationToken
CancellationToken 작업이 완료 될 때까지 기다리는 동안 관찰할 입니다.
반환
가 false이면 HasResult EF는 정상적으로 계속됩니다.
가 true이면 HasResult EF는 수행하려고 하던 작업을 표시하지 않고 대신 사용합니다 Result .
결과를 변경하려고 하지 않는 인터셉터에 대해 이 메서드의 구현은 전달된 값을 반환 result
하는 것입니다. FromResult<TResult>(TResult)
