- org.cojen.util.RefCache<K,V>
- - org.cojen.util.WeakKeyCache<K,V>
  - - org.cojen.util.WeakIdentityCache<K,V>

All Implemented Interfaces:

Cache<K,V>
```
public class WeakIdentityCache<K,V>
extends WeakKeyCache<K,V>
```
Simple thread-safe cache which evicts entries via a shared background thread. Cache permits null values, but not null keys. Keys are compared for equality via identity comparison instead of using the key's built-in hashcode and equals methods.
