Class HashBag
- Bag, Collection, Serializable, Bag
public class HashBag
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.
