All Implemented Interfaces:

Collection, Set

public class ValueSet

extends AbstractSet

This Set is created from a Map and will allow iteration over its values as a Set. This implies that all values added to the Map are distinctive, for instance because each value contains its own key. The methods equals() and hashCode() of the values need to be implemented properly for this to work.
