ConcurrentMapAcceptingNullVals (Apache Brooklyn)

java.lang.Object
- brooklyn.internal.storage.impl.ConcurrentMapAcceptingNullVals<K,V>

All Implemented Interfaces:

java.util.concurrent.ConcurrentMap<K,V>, java.util.Map<K,V>
```
public class ConcurrentMapAcceptingNullVals<K,V>
extends java.lang.Object
implements java.util.concurrent.ConcurrentMap<K,V>
```
A decorator for a ConcurrentMap that allows null values to be used. However, values() and entrySet() return immutable snapshots of the map's contents. This may be revisited in a future version.
