org.apache.commons.collections.bag.TreeBag
Implements SortedBag, using a TreeMap to provide the data storage. This is the standard implementation of a sorted bag.
Order will be maintained among the bag members and can be viewed through the iterator.
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) @version $Revision: 1.9 $ $Date: 2004/02/18 00:56:25 $ @author Chuck Burdick @author Stephen Colebourne
