方法详细资料

getEntityName

String getEntityName()

The name of the entity to which this metadata applies.

返回:

The entity name

isEnhancedForLazyLoading

boolean isEnhancedForLazyLoading()

Has the entity class been bytecode enhanced for lazy loading?

返回:

true indicates the entity class is enhanced for Hibernate use in lazy loading; false indicates it is not

getLazyAttributesMetadata

LazyAttributesMetadata getLazyAttributesMetadata()

createEnhancedProxy

PersistentAttributeInterceptable createEnhancedProxy(EntityKey keyToLoad,
                                                     boolean addEmptyEntry,
                                                     SharedSessionContractImplementor session)

Create an "enhancement as proxy" instance for the given entity

injectInterceptor

LazyAttributeLoadingInterceptor injectInterceptor(Object entity,
                                                  Object identifier,

参数:

entity - The entity into which built interceptor should be injected

identifier -

session - The session to which the entity instance belongs.

返回:

The built and injected interceptor
