成员函数文档

ForeverIterator::ForeverIterator()

为 For (ForeverIterator()) >> Do {} 构造构建永不终止的迭代器。

注意： 如果 Do 主体指定了并行模式，请务必小心--在这种情况下，QTaskTree 可能会实例化无限多的任务。

使用示例

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

const autoonNumberCheck= [luckyNumber]{const intdrawnNumber=QRandomGenerator().global()->bounded(maxNumber)；    qDebug() << "You have drawn:" << drawnNumber;
   boolwon=drawnNumber==luckyNumber;if(won)        qDebug() << "You have won! Congratulations!";
   returnwon; };constGroup recipe=For (ForeverIterator())>>Do { stopOnSuccess,timeoutTask(1s)、    QSyncTask(onNumberCheck) };

QTaskTree 启动recipe 时的可能输出：

Today's lucky number is: 8
Let's start the drawing...
You have drawn: 2
You have drawn: 2
You have drawn: 6
You have drawn: 7
You have drawn: 9
You have drawn: 8
You have won! Congratulations!
