All Implemented Interfaces:

Iterable<Map.Entry<K,V>>, Collection<Map.Entry<K,V>>, Set<Map.Entry<K,V>>

public class SetOverMap<K,V>
extends AbstractSet<Map.Entry<K,V>>

A special helper class to treat a map as a collection of entries and retain the ability to retrieve the map. Map.entrySet().add() is not always supported and its usually not possible to get the map out again.
