Steve and Nat: Encapsulate Generics

February 21st, 2011

I’m reading Growing Object-Oriented Software, Guided by Tests, by Steve Freeman and Nat Pryce. I was happy to find that the authors share a similar view on constructed generic types as I do.

Our rule of thumb is that we try to limit passing around types with generics […]. Particularly when applied to collections, we view it as a form of duplication. It’s a hint that there’s a domain concept that should be extracted into a type.

A less blunt way of saying what I tried to say in my own post.

If you’re interested in the book I can strongly recommend it. Although I’m only half-way through it I can already tell it’s the best TDD book I have read so far. I’ll have a brief review up in a coming post.

Cheers!
