------------------------------------
Summary: CacheInvalidationFilter - broadcast cache invlidation
events to interested listeners
Key: CAY-2259
URL: https://issues.apache.org/jira/browse/CAY-2259
Project: Cayenne
Issue Type: Task
Affects Versions: 4.0.M5
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
With cayenne-jcache we lost the ability to invalidate caches not handled by
Cayenne. The API for CacheManager's caches introspection requires the caller to
know the generic parameters of a named cache. So we can no longer invalidate
caches that were not created for Cayenne (and that are known to be of type
"Cache<String, List>").
So now we need to do two things:
* JCacheQueryCache.removeGroup(..) should only attempt to remove caches that
are in the "seenCacheNames" collection.
* CacheInvalidationFilter should allow registration of listeners, so that the
user code outside of Cayenne could receive explicit cache group events and
flush their own caches manually.
Not ideal, but perhaps not such a bad idea on the long run. It prevents Cayenne
from overstepping its boundaries.
