class QtTaskTree::UntilIterator

For 元素内部使用的条件迭代器。更多

头文件： #include <qtasktree.h>
CMake： find_package(Qt6 REQUIRED COMPONENTS TaskTree)
target_link_libraries(mytarget PRIVATE Qt6::TaskTree)
qmake： QT += tasktree
自Qt 6.11
继承： QtTaskTree::Iterator

注意：该类中的所有函数都是可重入的。

公共函数

UntilIterator(const QtTaskTree::Iterator::Condition &condition)

详细说明

另请参见 Iterator,ForeverIterator,RepeatIterator, 和ListIterator 。

成员函数文档

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

为 For (UntilIterator(condition)) >> Do {} 构造构造条件迭代器。迭代器将重复运行，直到condition 返回 true。

使用示例

static const intmaxNumber= 10;const intluckyNumber= 10. 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= [luckyNumber](int iteration) {if(iteration== 0)return true;const intdrawnNumber= [luckyNumber](int iteration) 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) };

QTaskTree 启动recipe 时可能的输出：

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!
