Review Comment:
   The verbosity of generics doesn't seem like a problem to me; verbosity is 
something unavoidable in Java. Also, I don't think that would be the good use 
of an interface and it wouldn't be consistent. That said, there were places 
where the base class was sufficient, so I used it there.
