Issue Description	If we don't there is a possibility that caching reads (like getFromIDSet(Set) and get(int)) will return data going back to the first time the JVM was started up. That would not be good. Create a CacheEntry object that stores the CacheKey as well as the expiration time. You will probably want to create an ExpiringCache abstract class, that uses a Map instead of our borked List implementation. Instead of preserving items based on access date, let's preserve them based on expiration date. Your CacheEntryKey object should be naturally sortable based on expiration date, and when the cache overflows, purge out the oldest (ie. first) entry.
ISSUE COMMENTS
Luke Kolin (DVA043) 07/05/2005 17:04 ET	AbstractCache and DAOCache have been replaced with AgingCache and ExpiringCache, which exhibit the behavior we always wanted in our caches.
