SetFromLiveMap (Apache Brooklyn)

java.lang.Object
- java.util.AbstractCollection<E>
- - java.util.AbstractSet<E>
  - - org.apache.brooklyn.util.collections.SetFromLiveMap<E>

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>
```
public class SetFromLiveMap<E>
extends java.util.AbstractSet<E>
implements java.util.Set<E>, java.io.Serializable
```
Creates a Set backed by a given map (using the map's Map.keySet() for the contents of the set).
As Collections.newSetFromMap(Map) and guava's Sets.newSetFromMap(Map), but accepts a non-empty map. Also supports others modifying the backing map simultaneously, if the backing map is a ConcurrentMap.
