Cache

All Known Subinterfaces:

```
public interface Cache
extends Cache
```
Provides an API for querying/managing the second level cache regions.
CAUTION: None of these methods respect any isolation or transactional semantics associated with the underlying caches. Specifically, evictions perform an immediate "hard" removal outside any transactions and/or locking scheme(s).
