2021-10-10 For me, modeling is simply describing the "things" that I want to appear in a class (structure) as I can see them. That is my method. [長年日記]

Sometimes I am asked, "Mr. Ebata, when you create a simulator, what kind of modeling do you do to define the interface (I/F)?"

My answer is always the same.

"I don't think about it."

-----

In my programming, I just describe things in the real world in a structure (class) and I/F later when things need to communicate with each other.

I believe that this kind of design concept is called "object design" and programming based on this concept is just called "object-oriented programming".

There is only one advantage to this programming --

"Easy". This is the only word that comes to mind.

However, in order to make this "easy", you need to be willing to not use any of the features of "object-oriented programming".

I don't use "inheritance" or "generalization" because they are too much trouble when debugging.

"Multiple inheritance" is sure to be confusing.

I believe that if you need "polymorphism," you're not very good at making it.

I find "private" and "public" annoying to death, so I just use "public" for everything.

If you use this kind of thing, the readability of your program will get really bad. It's not very readable.

Well, maybe it's because this is a "personal level" programming of a researcher that we can think this way, but

For me, modeling is simply describing the "things" that I want to appear in a class (structure) as I can see them. That is my method.

Other than that, I think it's fine to learn when you need it -- although I wonder if the time is coming.
