Just recently I came across a situation where I needed to determine if a specific method was available in a CFC. I have a case where I'm creating specific methods for specific departments. So in the code, if Department A has a method, do this, if not do that. As it turns out, this is super super simple to do from within the CFC.
How simple is it?
It is so simple that I couldn't believe it when I tried it and it really worked. I had to do a double take because, well, I'm really not used to my code working right the first time. I actually felt smert for a change, like I knew what I was doing!
