[explicit] RepeatIterator::RepeatIterator(qsizetype count)
Construye el iterador repetitivo para la construcción For (RepeatIterator(count)) >> Do {}. El iterador se repetirá count veces.
Ejemplo de uso:
static const int maxTries = 5;static const int maxNumber = 10;const int luckyNumber = QRandomGenerator().global()->bounded(maxNúmero); 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(maxNúmero); qDebug() << "You have drawn:" << drawnNumber; return númeroDibujado == númeroDeLaSuerte; };const auto onDone = [](DoneWith resultado) { if (resultado == DoneWith::Éxito) qDebug() << "You have won! Congratulations!"; else if (result == DoneWith::Error) qDebug() << "You have lost. Try again."; };const Group recipe { For (RepeatIterator(maxTries))>> Do { stopOnSuccess,timeoutTask(1s), QSyncTask(onNumberCheck) },onGroupDone(onDone) };
La posible salida cuando el recipe es iniciado por el QTaskTree, y termina con éxito:
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!
En caso de que termine con un error, la salida podría ser como:
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.
