Andrus Adamchik updated CAY-2259:
---------------------------------
Description:
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>").
A few changes to address this:
1. Internally use "untyped" caches for storage. This would allow the same
caches to be reused by the code outside Cayenne.
2. Add API to QueryCache to handle invalidation of typed caches with known key
and value types. Extend @CacheGroups annotation to specify cache generics
"signatures", add support for it in CacheInvalidationFilter.

A possible solution would be to extend @CacheGroups annotation to specify cache
generics "signatures". And also change QueryCache API, perhaps deprecating
'removeGroup(String)' in favor of 'clearCache(String name, Class keyType, Class
valueType)'
