HashBag (The Adobe AEM Quickstart and Web Application. 6.6.0)

java.lang.Object
- org.apache.commons.collections.bag.AbstractMapBag
- - org.apache.commons.collections.bag.HashBag

All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable, java.util.Collection, Bag
```
public class HashBag
extends AbstractMapBag
implements Bag, java.io.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)
