[explicit] UntilIterator::UntilIterator(const QtTaskTree::Iterator::Condition &condition)
Construit l'itérateur conditionnel pour la construction For (UntilIterator(condition)) >> Do {}. L'itérateur se répète jusqu'à ce que condition retourne vrai.
Exemple d'utilisation :
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) } ;
La sortie possible lorsque le recipe est démarré par le QTaskTree:
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!
