[jira] Closed: (COLLECTIONS-218) CollectionUtils.select() does not
return passed in collection
[ http://issues.apache.org/jira/browse/COLLECTIONS-218?page=all ]
Stephen Colebourne closed COLLECTIONS-218.
------------------------------------------
Resolution: Won't Fix
This change is logically sensible. However, it is backwards incompatible (changing a return type is binary incompatible). As such e cannot incorporate this proposal. Sorry.

> Key: COLLECTIONS-218
> URL: http://issues.apache.org/jira/browse/COLLECTIONS-218
> Project: Commons Collections
> Issue Type: Improvement
> Components: Core
> Affects Versions: 3.2
> Reporter: Stephen Kestle
> Assigned To: Stephen Colebourne
> Attachments: CollectionUtils select return.patch
>
>
> collect has the following methods:
> Collection collect(Collection inputCollection, final Transformer transformer)
> Collection collect(Collection inputCollection, final Transformer transformer, final Collection outputCollection)
> The first creates an ArrayList(), where the second takes an outputCollection and, for convenience, returns it.
> Select (and selectReject) currently the following methods:
> Collection select(Collection inputCollection, Predicate predicate)
> void select(Collection inputCollection, Predicate predicate, Collection outputCollection)
> I propose changing the bottom method to return the passed in outputCollection. It would simplify calling code.
