Class ForwardingMap.StandardValues

java.lang.Object

java.util.AbstractCollection<V>

com.google.common.collect.ForwardingMap.StandardValues

All Implemented Interfaces:

Iterable<V>, Collection<V>

Enclosing class:

ForwardingMap<K,V>

@Beta
protected class ForwardingMap.StandardValues
extends AbstractCollection<V>

A sensible implementation of Map.values() in terms of the following methods: ForwardingMap.clear(), ForwardingMap.containsValue(java.lang.Object), ForwardingMap.isEmpty(), ForwardingMap.size(), and the Set.iterator() method of ForwardingMap.entrySet(). In many cases, you may wish to override ForwardingMap.values() to forward to this implementation or a subclass thereof.

Since:

10.0
