C++ Reactive Programming

The philosophy of our book

The purpose of this chapter is to introduce readers to the key interfaces of the reactive programming mode they are—IObservable<T> and IObserver<T>. They are in fact the duals of the IEnumerable<T> and IEnumerator<T> interface. We learned how to model those interfaces in classic C++ (well, mostly) and had toy implementations of all of them. Finally, we implemented a GUI program that captures mouse movements and notifies a list of Observers. These toy implementations are to get our feet wet with the ideas and ideals of the Reactive programming model. Our implementations can be considered as implementing of OOP-based reactive programming.

To be proficient in C++ reactive programming, a programmer has to be comfortable ...
