Class EntityLoader

java.lang.Object

org.hibernate.loader.Loader

org.hibernate.loader.OuterJoinLoader

org.hibernate.loader.entity.AbstractEntityLoader

org.hibernate.loader.entity.EntityLoader

All Implemented Interfaces:

UniqueEntityLoader

public class EntityLoader
extends AbstractEntityLoader

Loads an entity instance using outerjoin fetching to fetch associated entities.
The EntityPersister must implement Loadable. For other entities, create a customized subclass of Loader.
