Not exactly sure, but couldn't you define an @Interceptor class that defines a
pointcut around getTopics() then use Reflection to grab the @Where annotation
and change the topci_type to DF? Not sure if I'm missing something since I"m
fairly new to AOP and design but it seems possible at first glance.
