C++ Reactive Programming

From Design patterns to Reactive programming

Even though the design pattern movement is aligned with OOP, and reactive programming is aligned towards FP, there are close similarities between them. In a previous chapter(Chapter 5, Introduction to Observables), we learned the following:

• The OOP model is good for modeling the structural aspects of a system.
• The FP model is good for modeling the behavioral aspects of a system.

To illustrate the connection between OOP and reactive programming, we will write a program that will traverse directories to enumerate files and sub-folders within a given folder.

We will create a composite structure that contains the following:

• A FileNode (inherits from the abstract class  EntryNode) that models file ...
