> QueryCache: support for referencing type-safe caches
> ----------------------------------------------------

> 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: Nikita Timofeev
> Fix For: 4.0.M6
>
>
> 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.
