类 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

所有已实现的接口:

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.

Return false is this loader is a batch entity loader

覆盖:

isSingleRowLoader 在类中 AbstractEntityLoader

getCompositeKeyManyToOneTargetIndices

public int[][] getCompositeKeyManyToOneTargetIndices()

覆盖:

getCompositeKeyManyToOneTargetIndices 在类中 Loader
