Synthetic? Yes. Contrived? No. I've seen this sort of thing in my own and other people's Java code, where you know what class it is but not the most-derived subclass. That's how polymorphism happens.
- pvg 17y agoRight. It doesn't happen by rooting around objects looking for methods by name. That's usually a sign of some misdesign that's making you re-invent the polymorphic mechanisms of the language yourself. True both in Java and Python.
- ighost 17y agoI agree that polymorphism is the "right way" if there's already a class hierarchy established. If the superclass-subclass relationships aren't in place for you (worse yet, they're not set up how you want them to be set up), this hack accomplishes a similar effect with no refactoring.
