You Don’t Understand Delegation

Okay, for reasons best understood by myself, I attempted to create delegates under C++ (no templates because, frankly, they just make an ugly language look uglier). I managed to hack something that worked, but have grave concerns that it is incorrect.

I was right.

In his article¬†The Gang Of Four Is Wrong And You Don’t Understand Delegation, Jim Gay goes through what we THINK delegation is and what delegation REALLY is.

And he is right.

I spend a lot of time in Objective C. I love Objective C. It makes OOP fun.¬†In Objective C you can do true delegation. It isn’t a hack, it is part of the language.

C++ is a lot like Darth Vader. It is the dark side. You don’t program in C++, C++ programs you (as they say in Russia). C++ is the program of “no”. NO you can’t have delegates. NO you can’t do that (because I arbitrarily said so). The list of No’s goes on and on. Why have people flocked to C#? It is less “no’ish”.

Other than that, it’s not bad. Perhaps one day I’ll write a book titled “C++ – The Good Parts” on how to write readable, useable, and most important, fun C++.

Rather than summarize a summation of a long article, read Gay’s article. It won’t take long. You will learn something important.
