Re: Java Accessors Are They Evil?

[James Perkins <jrperkinsjr@xxxxxxxxx>]

Wow, I feel like I've been doing it all wrong now. I am starting to see what
you are saying though. I just need to play with it a bit I guess.

Do you know of any good articles or books that explain this kind of pattern?
I was looking last night, but wasn't sure what to look for. I did see plenty
of examples with getters and setters though.

Thanks,
James R. Perkins
