getMappedClass

public Class getMappedClass()

从接口复制的说明: Tuplizer

Return the pojo class managed by this tuplizer.

Need to determine how to best handle this for the Tuplizers for EntityModes other than POJO.

todo : be really nice to not have this here since it is essentially pojo specific...

getConcreteProxyClass

public Class getConcreteProxyClass()

Returns the java class to which generated proxies will be typed.

todo : look at fully encapsulating PersistenceContext.narrowProxy(java.lang.Object, org.hibernate.persister.entity.EntityPersister, org.hibernate.engine.spi.EntityKey, java.lang.Object) here, since that is the only external use of this method

返回:

The java class to which generated proxies will be typed

afterInitialize

public void afterInitialize(Object entity,
                            SharedSessionContractImplementor session)

determineConcreteSubclassEntityName

public String determineConcreteSubclassEntityName(Object entityInstance,
                                                  SessionFactoryImplementor factory)

从接口复制的说明: EntityTuplizer

Given an entity instance, determine the most appropriate (most targeted) entity-name which represents it. This is called in situations where we already know an entity name for the given entityInstance; we are being asked to determine if there is a more appropriate entity-name to use, specifically within an inheritance hierarchy.

For example, consider a case where a user calls session.update( "Animal", cat );. Here, the user has explicitly provided Animal as the entity-name. However, they have passed in an instance of Cat which is a subclass of Animal. In this case, we would return Cat as the entity-name.

null may be returned from calls to this method. The meaning of null in that case is assumed to be that we should use whatever explicit entity-name the user provided (Animal rather than Cat in the example above).

参数:

entityInstance - The entity instance.

factory - Reference to the SessionFactory.

返回:

The most appropriate entity name to use.

getEntityNameResolvers

public EntityNameResolver[] getEntityNameResolvers()

从接口复制的说明: EntityTuplizer

Get any EntityNameResolvers associated with this Tuplizer.

返回:

The associated resolvers. May be null or empty.
