Class HashBag

java.lang.Object
org.apache.commons.collections.bag.AbstractMapBag
org.apache.commons.collections.bag.HashBag
All Implemented Interfaces:
Serializable, Iterable, Collection, Bag

public class HashBag extends AbstractMapBag implements Bag, Serializable
Implements Bag, using a HashMap to provide the data storage. This is the standard implementation of a bag.

A Bag 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. It is important to read the interface javadoc carefully as several methods violate the Collection interface specification.

Since:
Commons Collections 3.0 (previously in main package v2.0)
