Sometimes I wonder why Sun never deprecated Hashtable, Vector, and Enumeration... this "unofficial deprecation" thing doesn't make sense to me.

The 2.1 Enumeration classes are:
org.apache.commons.collections.iterators.EnumerationIterator Adapter to make Enumeration instances appear to be Iterator instances.

So perhaps the "anti Enumeration" stance is more feeling than policy ;-)
It seems that in a lot of cases, Enumerations enumerate over collection types of things as in ResourceBundle.getKeys() for example.
Which is why (to me) an EnumerationUtils class seems at home here.
More thoughts?
Unfortunately, even though the dreaded Enumeration interface has been unofficially deprecated, important APIs like Servlet depend on it. I think anything that makes it easier to to deal with these legacy Enumerations is a good thing.

Yes, we are pretty much anti Enumeration. There are some methods here
and
there though. Stephen

The only problem is that Enumerations aren't really a part of the collections framework. Of course, this is just a technicality...
but it
may be the reason that a EnumerationUtils class hasn't been created.
Cany anyone else confirm this?

Hello,
In 2.1, I have code like:
java.util.ResourceBundle resourceBundle = ... List keysList = IteratorUtils.toList(new EnumerationIterator(resourceBundle.getKeys()));
Do we want an EnumerationUtils class, which, for now (a la XP)
would
have a---------------------------------------------------------------------
toList() method and grow from there?
Thanks, Gary
