public interface CacheRegenerator
Implementations of CacheRegenerator
are used in autowarming to populate a new cache
based on an old cache. regenerateItem
is called for each item that should be inserted into the new cache.
Implementations should have a noarg constructor and be thread safe (a single instance will be used for all cache autowarmings).
