Subject [jira] Created: (COLLECTIONS-243) generic versions of some more classes
Date Mon, 12 Mar 2007 05:48:09 GMT
generic versions of some more classes
-------------------------------------

                 Key: COLLECTIONS-243
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-243
             Project: Commons Collections
          Issue Type: Improvement
          Components: Collection
    Affects Versions: Generics
         Environment: OS X
            Reporter: Edwin Tellman
            Priority: Minor
             Fix For: Generics


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.
