Master the Design of Classes (Part 5)
Watch the full video: • Master the Design of Classes
Let me show you the hardest problem in object-oriented modeling, on an example.
This interface is modeling a book edition as an abstract concept.
We call that an open-ended model because it can attain infinitely many implementations over time.
There can be an ordinal edition, such as the first, the second, and so on.
There can be an annual edition, like the year 2024.
A seasonal edition and a monthly edition come to mind.
The number of types implementing this interface is only bounded by your imagination.
The long video demonstrates this design process.
I will only show you the impossible part of it, which sometimes appears in practice.
What if we needed to sort the book's editions? Implementing the IComparable interface on such an open-ended type is impossible.
Give it a try, and tell me what you came up with.
