| May 9, 2016 at 17:11 | comment | added | amon | @CodeYogi Data hiding is the most common kind of encapsulation. However, the way data is stored internally by an object is not the only implementation detail that should be hidden. It's equally important to hide how the public interface is implemented, e.g. whether I use any helper methods. Such helper methods should also be private, generally speaking. So to summarize: encapsulation is a principle, whereas data hiding is an encapsulation technique. | |

| Mar 18, 2014 at 13:36 | comment | added | amon | @OrangeDog Yes, there is no universally accepted definition of OOP, but I needed a definition to work with. So I picked something that is as close to the truth as I could get without writing a whole dissertation about it. However, I do regard dynamic dispatch as the single major distinguishing feature of OOP from other paradigms. Something that looks like OOP but actually has all calls resolved statically is really just modular programming with ad-hoc polymorphism. Objects are a pair of methods and data, and are as such equivalent to closures. | |
