Trying to learn software design by looking at code is kind of like trying to learn about architecture looking at the bricks that make up a building.

To learn about design you need a wider perspective. You can theoretically learn it from code but it won’t be most effective. Look at great documentation and literature about design instead.

Yeah, I guess without the context I wouldn't really understand why it was designed that way. Or know what situations a design like that would be good for.

Is there any documentation or literature that has helped you?
