Well, when you put it that way, your proposed change does result in much simpler code. The resulting code isn't that much more than the switch. I hope it is now easy enough to read. These functions are private to the class and just exist to be helpers. I don't see a need to put the switch table into a different function, but I'm willing to be convinced.
