Class HashBag

  • All Implemented Interfaces:, java.lang.Iterable, java.util.Collection, Bag

    public class HashBag
    extends AbstractMapBag
    implements Bag,
    Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.
    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.
