Subject Re: enums as ordinals?
Date Mon, 18 Jan 2010 11:58:35 GMT
I wrote a generic EnumTypeHandler some time ago which made things quite a
bit easier. I don't have access to the source right now but I'll try to dig
it out this evening if needed, it's fairly basic and straightforward (and I
think even based off some protoype handler I found somewhere else).

Otherwise I could never think of another way of doing it. I think overall
though it is a nice way to abstract out the handling of custom types, even
if Enums could be considered first class they do afford some magic that
would be difficult to handle in a standard way.

Cheers,
