java.lang.Objectorg.hibernate.collection.AbstractPersistentCollection
org.hibernate.collection.PersistentBag
public class PersistentBag
An unordered, unkeyed collection that can contain the same element multiple times. The Java collections API, curiously, has no Bag. Most developers seem to use Lists to represent bag semantics, so Hibernate follows this practice.
