## 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>

      @Beta
      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.
  Since:
    10.0
