멤버 함수 문서

[explicit] RepeatIterator::RepeatIterator(qsizetype count)

For (RepeatIterator(count)) >> Do {} 구문에 대한 반복 이터레이터를 구축합니다. 이터레이터는 count 번 반복합니다.

사용 예시:

static const int maxTries = 5;static const int maxNumber = 10;const int luckyNumber = QRandomGenerator().global()->bounded(maxNumber);
qDebug() << "Today's lucky number is:" << luckyNumber;
qDebug() << "You have" << maxTries << "lottery tickets.";
qDebug() << "Let's start the drawing...";

const auto onNumberCheck = [luckyNumber] { const int drawnNumber = QRandomGenerator().global()->bounded(maxNumber);    qDebug() << "You have drawn:" << drawnNumber;
   return drawnNumber== luckyNumber; };const auto onDone = [](DoneWith result) { if (result== DoneWith::Success)        qDebug() << "You have won! Congratulations!";
   else if (결과== DoneWith::Error)        qDebug() << "You have lost. Try again.";
};const Group recipe { For (RepeatIterator(maxTries))>> Do { stopOnSuccess,timeoutTask(1s),        QSyncTask(onNumberCheck) },onGroupDone(onDone) };

recipe 이 QTaskTree 에 의해 시작되어 성공으로 완료되었을 때 가능한 출력입니다:

Today's lucky number is: 6
You have 5 lottery tickets.
Let's start the drawing...
You have drawn: 9
You have drawn: 6
You have won! Congratulations!

에러로 끝나는 경우 출력은 다음과 같습니다:

Today's lucky number is: 8
You have 5 lottery tickets.
Let's start the drawing...
You have drawn: 1
You have drawn: 7
You have drawn: 6
You have drawn: 7
You have drawn: 2
You have lost. Try again.
