- org.cache2k.core.ConcurrentMapWrapper<K,V>

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>
```
public class ConcurrentMapWrapper<K,V>
extends Object
implements ConcurrentMap<K,V>
```
ConcurrentMap interface wrapper on top of a cache. The map interface does not cause calls to the cache source. An attached writer is called.
