Force super class to not call overloaded methods of the subclass

I have a base class and subclass inheriting from it. Base class has method A. Subclass overloads that method. I want to force the base class to use (only in some places) it's own method, not the one overloaded by subclass. Is there any way to do it?
Thank you

Hi Naum,
When you create an object obj of a superclass and then use obj to call the overloaded (or any) method of the superclass, the method defined in the superclass is called and not the one of the subclass.

I am facing the same issue in my code and I have been wasting a few weeks now to find out how I can prevent the SuperClass to call Subclass overloaded method. This is an absolutely silly OOP behavior in MATLAB. Why isn't there an easy way to do so?

You can call a superclass method even if the subclass overloads or overrides that method only from within that method itself. So if the superclass and subclass both define a method foo(), inside the subclass foo() method you can call the superclass's foo() method.
You can also have the subclass's constructor call the superclass's constructor (even though they don't have the same name.)

Thank you, I appreciate your response, although that is still not quite helpful. I can bypass the whole problem if there was a way to set the superclass components of the subclass in an assignment. For example,
```matlab
self@superclass = superObject
```
where superObject is an object of superclass. I know some other languages allow such a syntax. Is there a MATLAB equivalent for this functionality?

I'm not sure I understand what you're trying to do. Can you describe in a little more detail what problem you're trying to solve (not how you're hoping to implement it; describe the why not the how), or perhaps what design pattern you're trying to implement? With that information we may be able to suggest an approach to achieve your goal (or explain if it smells a bit funny to us.)
