Stephen Smith commented on COLLECTIONS-243:
-------------------------------------------

Could we rename this issue to indicate specifically which classes in collections_jdk5_branch these changes genericise?

> I added generics to some more classes and fixed some compilation problems.
> The generic version of Transformer required the input and output types to be identical.  This seemed to me to reduce the usefulness of transformed collections, as transforming one type into another seems like it would be a fairly common operation.  I'm not sure how to fix this, however, as it also doesn't seem feasible to have a generic TransformedCollection with different input and output types that implements Collection<E>.  Anyway, this patch de-generifies TransformedCollection, which also fixes some compilation problems.  Please disregard this change if you disagree and have a better solution.
