Right. Encapsulation doesn't imply validation; however, neither do
[GS]etters necessarily break encapsulation. Information can still be
hidden in these ugly little things and we can still attempt to
protect our users (i.e. other programmers) from themselves and "from
the guts".
It's not important though, I get your point.
I like the way Ruby's "accessors" are all sugared up to look like
properties.
but yea i was really just getting at the point that obsession of a
principle can ultimately undermine it.
Definitely, it's a good point.
I see this quite a bit where I work. Guys get all caught up in
severely over-designing "perfect" systems. Instead of doing a bit of
design, and then working smart on an implementation while keeping the
code nice and flexible, etc., they spend a massive amount of time and
effort calling meetings, discussing stuff, and diagramming it out on
whiteboards. Then when they finally code it and figure out it's not
going to work, it's back to the drawing board. Meanwhile, two or
three months of a ten month dev cycle have evaporated. And, we're
certainly not working on rocket science.
Or, the guy who discovered some geeky C++ delegate system, which has
now infected every corner of his team's code. Unfortunately, it's
just about the nastiest thing to use and they're in way too deep to
gut it.
Or, the guy who thinks namespaces are mega super important, so
everything in the project is 3, 4, or 5 namespaces deep. Not fun.
Or, the guy who is a "const correctness" fanatic. At the beginning
of a project he said, some day you're going to thank me for making it
all this way. At the end of the project I ripped it completely out.
Never thanked him.
