[explicit] UntilIterator::UntilIterator(const QtTaskTree::Iterator::Condition &condition)
For (UntilIterator(condition)) >> Do {} 구문에 대한 조건부 이터레이터를 구축합니다. 이터레이터는 condition 이 참을 반환할 때까지 반복됩니다.
사용 예시:
static const int maxNumber = 10;const int luckyNumber = QRandomGenerator().global()->bounded(maxNumber); qDebug() << "Today's lucky number is:" << luckyNumber; qDebug() << "Let's start the drawing..."; const auto onConditionCheck = [luckyNumber](int iteration) { if (iteration== 0) return true; const int drawnNumber = QRandomGenerator().global()->bounded(maxNumber); qDebug() << "You have drawn:" << drawnNumber; bool won = drawnNumber== luckyNumber; if (won) qDebug() << "You have won! Congratulations!"; return !won; };const Group recipe = For (UntilIterator(onConditionCheck))>> Do { timeoutTask(1s, DoneResult::Success) };
QTaskTree 에서 recipe 이 시작될 때 가능한 출력입니다:
Today's lucky number is: 7 Let's start the drawing... You have drawn: 2 You have drawn: 5 You have drawn: 0 You have drawn: 2 You have drawn: 4 You have drawn: 9 You have drawn: 9 You have drawn: 7 You have won! Congratulations!
