Commons Collections and Generics
Please correct me if I am mistaken about this:
There appears to be no generics-aware version of Commons Collections
within Apache Commons. For example, there is no interface Predicate<T>
in version 3,2,1; only a Predicate.
But I have for several years been using a generics-aware rewrite of
Commons Collections; see
https://github.com/megamattron/collections-generic. I have been very
satisfied with it, and use it exclusively in preference to the Apache
Commons version, but I expected that this would be adopted by Apache
Commons by now. But apparently it is not?
Am I correct about this? If so, can anyone explain why it has not, or if
there are plans to do so, or shed any other insight about this?
Thanks so much.
David Cogen

That's a matter of opinion of course.
For me, coding with functors in Java is not pretty and I'd rather wait for
closures in Java 8. A generics version of collection is reasonable but, as
Matt notes, it's a matter of wanting to put the time in.

Hi David,
[collections] has had generics in its trunk for years, but none of
its developers, myself included, have had time to get this rather
large codebase fully ready for a release. In any event, the general
idea in Commons is that [collections]' functor code is
semi-deprecated; we will recommend instead the use of the [functor]
component AFTER we get *that* component ready for release.
Sorry for the scylla/charybdis situation,
Matt
