Class ForwardingMultiset.StandardElementSet

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<E>

com.google.common.collect.ForwardingMultiset.StandardElementSet

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.Set<E>

Enclosing class:

ForwardingMultiset<E extends @Nullable java.lang.Object>

protected class ForwardingMultiset.StandardElementSet
extends java.util.AbstractSet<E>

A sensible implementation of Multiset.elementSet() in terms of the following methods: ForwardingCollection.clear(), ForwardingCollection.contains(java.lang.Object), ForwardingCollection.containsAll(java.util.Collection<?>), ForwardingMultiset.count(java.lang.Object), ForwardingCollection.isEmpty(), the Set.size() and Set.iterator() methods of ForwardingMultiset.entrySet(), and ForwardingMultiset.remove(Object, int). In many situations, you may wish to override ForwardingMultiset.elementSet() to forward to this implementation or a subclass thereof.
