C++ Reactive Programming

The key interfaces of a reactive program

To help you understand what is really happening inside a reactive program, we will write some toy programs to put things in proper context. From a software design point of view, if you keep concurrency/parallelism aside to focus on software interfaces, a reactive Program should have:

• An event source that implements IObservable<T>
• An event sink that implements IObserver<T>
• A mechanism to add subscribers to an event source
• When data appears at the source, subscribers will be notified

In this particular chapter, we have written code using classic C++ constructs. This is because we have not yet introduced Modern C++ constructs. We have also used raw pointers, something which we can mostly avoid while ...
