メンバ関数のドキュメント

[explicit] UntilIterator::UntilIterator(const QtTaskTree::Iterator::Condition &condition)

For (UntilIterator(condition)) >> Do {} 構造体の条件付きイテレータを構築します。このイテレータは、渡されたcondition が true を返すまで繰り返されます。

使用例：

static const intmaxNumber= 10;const intluckyNumber=().global()->bounded. QRandomGenerator().global()->bounded(maxNumber)；
qDebug() << "Today's lucky number is:" << luckyNumber;
qDebug() << "Let's start the drawing...";

const autoonConditionCheck= [luckyNumber](intiteration) {if(iteration== 0)return true;const intdrawnNumber=QRandomGenerator().global()->bounded(maxNumber)；    qDebug() << "You have drawn:" << drawnNumber;
   boolwon=drawnNumber==luckyNumber;if(won)        qDebug() << "You have won! Congratulations!";
   return !won; };constGroup recipe=For (UntilIterator(onConditionCheck))>>Do { timeoutTask(1s,DoneResult::Success) };

recipe がQTaskTree によって起動されたときに可能な出力：

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!
