public class HashMultiSet<E> extends AbstractMapMultiSet<E> implements java.io.Serializable
MultiSet
, using a HashMap
to provide the
data storage. This is the standard implementation of a multiset.
A MultiSet
stores each object in the collection together with a
count of occurrences. Extra methods on the interface allow multiple copies
of an object to be added or removed at once.
