This is for a DTO that inherits some fairly complicated describeType-based
auto-populate voodoo. It's already statically caching describeType info
(based on a getQualifiedClassName key), so that's no worry, and I've already
got all the info required for generating field-level change events as I go
through. I might refactor it and go back to those events when I get some
time. It needs to have some functionality pulled out into a generic
reflection util class anyway eventually :)
Cheers :)
