Why do you need to convert the booleans into size_t's?

I think a switch statement would be more appropriate here.  It would allow the compiler to give you an error if you're missing a case if you don't have a default.

It doesn't convert boolean to size_t, it converts an enum to a size_t so it can be compared to an integer. 

I just copied the style of the convertEnumerationToString() generated for all enums in IDL.

Is there a plan to do that for the 250 enums defined in IDL?

I see that now, but you put the parentheses in the wrong place.
