Re: Reflection Usage

[James Perkins <jrperkinsjr@xxxxxxxxx>]

Thanks Neill,
That was kind of what I had been reading. I've never really had the need for
reflection before, but it is very interesting and powerful.

I might go with storing the data in a Map with a descriptive enum as the
key. I think in this case that might be a bit more desirable. I did get a
working reflection though. It does however seem a bit slow, but it works
great!

Thanks for the input!
