\class QtConcurrent::QTaskBuilder
\inmodule QtConcurrent
\brief The QTaskBuilder class is used for adjusting task parameters.
\since 6.0
\ingroup thread
It's not possible to create an object of this class manually. See
\l {Concurrent Task} for more details and usage examples.
*/
/*!
\fn template <class Task, class ...Args> [[nodiscard]] QFuture<InvokeResultType> QtConcurrent::QTaskBuilder<Task, Args...>::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.
*/
/*!
\fn template <class Task, class ...Args> void QtConcurrent::QTaskBuilder<Task, Args...>::spawn(QtConcurrent::FutureResult)
Runs the task in a separate thread. This is a non-blocking call.
The task might not start immediately.
*/
/*!
\fn template <class Task, class ...Args> template <class ...ExtraArgs> [[nodiscard]] QTaskBuilder<Task, ExtraArgs...> QtConcurrent::QTaskBuilder<Task, Args...>::withArguments(ExtraArgs &&...args)
Sets the arguments \a args the task will be invoked with. The code is ill-formed
(causes compilation errors) if:
\list
\li This function is invoked more than once.
\li The arguments count is zero.
\endlist
*/
/*!
\fn template <class Task, class ...Args> [[nodiscard]] QTaskBuilder<Task, Args...> &QtConcurrent::QTaskBuilder<Task, Args...>::onThreadPool(QThreadPool &newThreadPool)
Sets the thread pool \a newThreadPool that the task will be invoked on.
*/
/*!
\fn template <class Task, class ...Args> [[nodiscard]] QTaskBuilder<Task, Args...> &QtConcurrent::QTaskBuilder<Task, Args...>::withPriority(int newPriority)
Sets the priority \a newPriority that the task will be invoked with.
*/
/*!
\typedef InvokeResultType
\relates QtConcurrent::QTaskBuilder
The simplified definition of this type looks like this:
\code
template <class Task, class ...Args>
using InvokeResultType = std::invoke_result_t<std::decay_t<Task>, std::decay_t<Args>...>;
\endcode
The real implementation also contains a compile-time check for
whether the task can be invoked with the specified arguments or not.
*/
/*!
\enum QtConcurrent::FutureResult
This enum type is used to invoke a special overload of
QtConcurrent::QTaskBuilder::spawn(QtConcurrent::FutureResult)
that doesn't return a future object.
\value Ignore
An auxiliary tag which introduced to improve code
readability.
