Daniel Pitts commented on OGNL-22:
----------------------------------
By "Alternative to this" I mean implementing OGNL-20 for these caches.
> Change the generics signature of ClassCache and ClassCacheImpl.
> ---------------------------------------------------------------

> Key: OGNL-22
> URL: https://issues.apache.org/jira/browse/OGNL-22
> Project: OGNL
> Issue Type: Improvement
> Reporter: Daniel Pitts
>
> Right now, ClassCache and ClassCacheImpl use some generics, but they do
> casting at the method level, which leads to possible ClassCastException, and
> doesn't quite support safe static typing.
> I'll be glad to provide a patch when I have some time. I'd like to have
> OGNL-21 resolved first, as it reduces the amount of code I'd have to touch to
> implement this change.
> The proposed signatures would be interface ClassCache<V> and class
> ClassCacheImpl<V> implements ClassCache<V>
> Changing the get/put methods to take and return "V" type objects.
> Alternative to this is to replace all of them with a "ConcurrentMap<Class<?>,
> V>".
