Subject: [collections] Desirability of typed and other validated Collections
Date: 06 Mar 2003 14:08:36 +0000
Is there any interest in creating typed Collections? Even though it looks like Java is providing generics with 1.5, this could serve as a good holdover until then,
- a TypedCollection(Integer.class) would only allow Integers to its add methods
- a TypedMap(String.class, Integer.class) would only allow String keys and Integer values
I understand that this type of thing could already by done using Predicates and CollectionUtils, but typed Collections, as well as other frequently used types of "validated" Collections, could be useful, such as a Collection that doesn't allow null values.
The code in CVS seems to be more up to date than the status doc describing the action items. Is downloading the code and taking a look around the best way to see who is working on what?
Thanks.
