Class OneToManyLoader

java.lang.Object
  extended bynet.sf.hibernate.loader.Loader
      extended bynet.sf.hibernate.loader.OuterJoinLoader
          extended bynet.sf.hibernate.loader.OneToManyLoader
All Implemented Interfaces:
CollectionInitializer
public class OneToManyLoader
extends OuterJoinLoader
implements CollectionInitializer

Loads one-to-many associations

The collection persister must implement QueryableCOllection. For other collections, create a customized subclass of Loader.
