Member Function Documentation
QtConcurrent::QTaskBuilder<Task, Args...> &QTaskBuilder::onThreadPool(QThreadPool &newThreadPool)
Sets the thread pool newThreadPool that the task will be invoked on.
QFuture<QtConcurrent::InvokeResultType> QTaskBuilder::spawn()
Runs the task in a separate thread and returns a future object immediately. This is a non-blocking call. The task might not start immediately.
void QTaskBuilder::spawn(QtConcurrent::FutureResult)
Runs the task in a separate thread. This is a non-blocking call. The task might not start immediately.
template <typename... ExtraArgs> QtConcurrent::QTaskBuilder<Task, ExtraArgs...> QTaskBuilder::withArguments(ExtraArgs &&... args)
Sets the arguments args the task will be invoked with. The code is ill-formed (causes compilation errors) if:
- This function is invoked more than once.
- The arguments count is zero.
QtConcurrent::QTaskBuilder<Task, Args...> &QTaskBuilder::withPriority(int newPriority)
Sets the priority newPriority that the task will be invoked with.
