# MapValuesCollection Class Reference

`#include <coherence/util/MapValuesCollection.hpp>`

Inherits ConverterCollections::ConverterCollection.

List of all members.

## Detailed Description

A wrapper class that provides the Collection interface for the value collection of a map.

It's returned by the default implementation of the AbstractMap::values() method. MapValuesCollection is based on the ConverterCollections functionality which will convert a map's entrySet into a KeySet

Note that because this ConverterSet is based on the Map's entrySet, all write operations on the set must be converted out to a method on the Map, not the keyset.
