How to imagine that all package classes implement the interface

Question

I am trying to model an MVC architecture for a small website. My models are all in a model package, and I have a model interface that the whole model should have. So my question was about this implementation. Is it possible to do so?

And if this is wrong, is there a way to say that all classes in the package implement the interface?

Answer 1

No. That would be wrong. You need to draw an implementation relation for each class that implements the interface.
