详细说明
管理单个任务树的执行。使用start() 方法执行给定的配方，重置任何可能正在运行的任务树。保证在任何给定时间内最多只有一个任务树在执行。

成员函数文档
QSingleTaskTreeRunner::QSingleTaskTreeRunner()
构建单个任务树运行程序。
[noexcept] QSingleTaskTreeRunner::~QSingleTaskTreeRunner()
销毁单个任务树运行程序。可能正在运行的任务树被删除。不会调用任务树的已完成处理程序。
另请参见 ~QTaskTree().
void QSingleTaskTreeRunner::cancel()
取消正在运行的任务树。调用任务树的完成处理程序DoneWith::Cancel 。
bool QSingleTaskTreeRunner::isRunning() const
返回单一任务树运行程序当前是否正在执行任务树。
void QSingleTaskTreeRunner::reset()
重置正在运行的任务树。不会调用任务树的完成处理程序。
template <typename SetupHandler = QtTaskTree::TreeSetupHandler, typename DoneHandler = QtTaskTree::TreeDoneHandler> void QSingleTaskTreeRunner::start(const QtTaskTree::Group &recipe, SetupHandler &&setupHandler = {}, DoneHandler &&doneHandler = {}, QtTaskTree::CallDone callDone = QtTaskTree::CallDoneFlag::Always)
无条件启动recipe ，重置任何可能正在运行的任务树。当新任务树即将启动时，调用setupHandler 。任务树结束时调用doneHandler 。根据传递的callDone 调用doneHandler 。
