How can I implement this better:
I'm partial to Apple's solution to this problem in the Core Foundation
on Mac OS X. Basically, the OS will take care of preferences for you,
and your application simply requests a preference associated with a
particular key (ie, there's a dictionary involved under the surface).
You don't even have to worry about reading and writing the file -- the
OS does that for you, and there's a synchronize routine you call when
you've made changes and want them written to disk. For Mac OS X, you
can access the Core Foundation preferences via my Core Foundation
wrapper classes (see the URL in my sig).
If you're doing cross-platform work, though, you can mimic this
behavior with a class that reads from a file into a dictionary pretty
easily. Somebody (Kevin Ballard, maybe?) has a class for turning XML
into a dictionary and vice versa, though I forget what it's called and
have never used it.
Beyond that, I wouldn't get complicated with it. You mentioned
factories and whatnot -- too messy. Not needed. Remember, whatever is
accessing a particular preference should know what to do with it better
than your abstracted preferences class!
