LazyAttributeLoadingInterceptor

public LazyAttributeLoadingInterceptor(String entityName,
                                       Object identifier,
                                       Set<String> lazyFields,
                                       SharedSessionContractImplementor session)

方法详细资料

getIdentifier

public Object getIdentifier()

从接口复制的说明: BytecodeLazyAttributeInterceptor

The id of the entity instance this interceptor is associated with

handleRead

protected Object handleRead(Object target,
                            String attributeName,
                            Object value)

从类复制的说明: AbstractInterceptor

Handle the case of reading an attribute. The result is what is returned to the caller

指定者:

handleRead 在类中 AbstractInterceptor

handleWrite

protected Object handleWrite(Object target,
                             String attributeName,
                             Object oldValue,
                             Object newValue)

从类复制的说明: AbstractInterceptor

Handle the case of writing an attribute. The result is what is set as the entity state

指定者:

handleWrite 在类中 AbstractInterceptor

fetchAttribute

public Object fetchAttribute(Object target,
                             String attributeName)

Fetches the lazy attribute. The attribute does not get associated with the entity. (To be used by hibernate methods)

loadAttribute

protected Object loadAttribute(Object target,
                               String attributeName)

isAttributeLoaded

public boolean isAttributeLoaded(String fieldName)

hasAnyUninitializedAttributes

public boolean hasAnyUninitializedAttributes()

toString

public String toString()

覆盖:

toString 在类中 Object

attributeInitialized

public void attributeInitialized(String name)

从接口复制的说明: BytecodeLazyAttributeInterceptor

Callback from the enhanced class that an attribute has been read or written

getInitializedLazyAttributeNames

public Set<String> getInitializedLazyAttributeNames()

从接口复制的说明: BytecodeLazyAttributeInterceptor

The names of all lazy attributes which have been initialized
