getMappedClass

public Class getMappedClass()

Description copied from interface: Tuplizer

Return the pojo class managed by this tuplizer. </p> Need to determine how to best handle this for the Tuplizers for EntityModes other than POJO. </p> todo : be really nice to not have this here since it is essentially pojo specific…

getConcreteProxyClass

public Class getConcreteProxyClass()

Description copied from interface: EntityTuplizer

Returns the java class to which generated proxies will be typed. <p/> 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

Returns:

The java class to which generated proxies will be typed

afterInitialize

public void afterInitialize(Object entity,
                            SharedSessionContractImplementor session)

Description copied from interface: EntityTuplizer

Called just after the entities properties have been initialized.

Specified by:

afterInitialize in interface EntityTuplizer

Overrides:

afterInitialize in class AbstractEntityTuplizer

Parameters:

session - The session initializing this entity.

determineConcreteSubclassEntityName

public String determineConcreteSubclassEntityName(Object entityInstance,
                                                  SessionFactoryImplementor factory)

Description copied from interface: 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 inheritence hierarchy. <p/> For example, consider a case where a user calls <tt>session.update( "Animal", cat );</tt>. Here, the user has explicitly provided <tt>Animal</tt> as the entity-name. However, they have passed in an instance of <tt>Cat</tt> which is a subclass of <tt>Animal</tt>. In this case, we would return <tt>Cat</tt> as the entity-name. <p/> <tt>null</tt> may be returned from calls to this method. The meaining of <tt>null</tt> in that case is assumed to be that we should use whatever explicit entity-name the user provided (<tt>Animal</tt> rather than <tt>Cat</tt> in the example above).

Parameters:

entityInstance - The entity instance.

factory - Reference to the SessionFactory.

Returns:

The most appropriate entity name to use.

getEntityNameResolvers

public EntityNameResolver[] getEntityNameResolvers()

Description copied from interface: EntityTuplizer

Get any EntityNameResolvers associated with this Tuplizer.

Returns:

The associated resolvers. May be null or empty.
