Examples of Bag

com.hp.hpl.jena.rdf.model.Bag
An RDF Bag container.
This interface defines methods for accessing RDF Bag resources. These methods operate on the RDF statements contained in a model. The Bag implementation may cache state from the underlying model, so objects should not be added to or removed a the Bag by directly manipulating its properties, whilst the Bag is being accessed through this interface.

When a member is deleted from a Bag using this interface, or an iterator returned through this interface, all the other members with higher ordinals are renumbered using an implementation dependent algorithm.
org.apache.cayenne.testdo.testmap.Bag
org.apache.commons.collections.Bag
Defines a collection that counts the number of times an object appears in the collection.
Suppose you have a Bag that contains {a, a, b, c}. Calling {@link #getCount(Object)} on a would return 2, whilecalling {@link #uniqueSet()} would return {a, b, c}.
NOTE: This interface violates the {@link Collection} contract. The behavior specified in many of these methods is not the same as the behavior specified by Collection. The noncompliant methods are clearly marked with "(Violation)". Exercise caution when using a bag as a Collection.
This violation resulted from the original specification of this interface. In an ideal world, the interface would be changed to fix the problems, however it has been decided to maintain backwards compatibility instead. @since Commons Collections 2.0 @version $Revision: 1.18 $ $Date: 2004/05/03 15:12:20 $ @author Chuck Burdick @author Stephen Colebourne

A bag permits duplicates, so it has no primary key @author Gavin King

A Bag is a group of statements that are an unorderd list which allow duplicates. The order in which the objects go in may not be the order in which they are returned. @author Andrew Newman @version $Revision: 2894 $
