Enhanced QtConcurrent based on AsyncFuture

Enhanced QtConcurrent based on AsyncFuture

AConcurrent contains functionality to support concurrent execution of program code. It is an enhanced version of QtConcurrent.

Installation

qpm install net.efever.aconcurrent

API

    #include <aconcurrent.h>

QFuture AConcurrent::runOnMainThread(Functor functor)

Run a function on the main thread and returns a QFuture to represent the result of the function. If the current thread is the main thread, it will be executed in next tick.

Example

auto worker = [=]() {

  // processing
  QFuture<int> future = AConcurrent::runOnMainThread([=]() {
    // Save the result on main thread
    return 0; // no error
  });
  AConcurrent::await(future); // future.waitForFinished();
};

QtConcurrent::run(worker);

QFuture AConcurrent::timeout(int value)

Returns a QFuture<void> which will be completed after msec specified by value.

QFuture AConcurrent::mapped(Sequence sequence, Functor worker)

Calls function once for each item in sequence and return a future with each mapped item as a result. It is similar to the QtConcurrent::mapped() but this version supports lambda function. The returned QFuture is cancelable.

QFuture AConcurrent::blockingMapped(Sequence sequence, Functor worker)

AConcurrent::await(future)

Wait until the input future is finished while keeping the event loop running.
