Class EntityLoader

java.lang.Object
  org.hibernate.loader.Loader
      org.hibernate.loader.BasicLoader
          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.
