[explicit] RepeatIterator::RepeatIterator(qsizetype count)

Construit l'itérateur répétitif pour la construction For (RepeatIterator(count)) >> Do {}. L'itérateur se répétera count fois.

Exemple d'utilisation :

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 (result == DoneWith::Error)        qDebug() << "You have lost. Try again.";
} ;const Group recipe { For (RepeatIterator(maxTries))>> Do { stopOnSuccess,timeoutTask(1s),        QSyncTask(onNumberCheck) },onGroupDone(onDone) } ;

La sortie possible lorsque le recipe est démarré par le QTaskTree, et se termine avec succès :

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!

S'il se termine par une erreur, la sortie peut ressembler à ce qui suit :

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.
