Class ForwardingMap.StandardEntrySet

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<E>

com.google.common.collect.ForwardingMap.StandardEntrySet

All Implemented Interfaces:

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

Enclosing class:

ForwardingMap<K extends @Nullable Object,V extends @Nullable Object>

protected abstract class ForwardingMap.StandardEntrySet
extends AbstractSet<E>

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