Interface ProxyFactory

All Known Implementing Classes:

ByteBuddyProxyFactory, MapProxyFactory

public interface ProxyFactory

Contract for runtime, proxy-based lazy initialization proxies.

Method Summary

Modifier and Type	Method	Description
HibernateProxy	getProxy(Object id, SharedSessionContractImplementor session)	Create a new proxy instance
void	postInstantiate(String entityName, Class<?> persistentClass, Set<Class<?>> interfaces, Method getIdentifierMethod, Method setIdentifierMethod, CompositeType componentIdType)	Called immediately after instantiation of this factory.

Method Details

postInstantiate

void postInstantiate(String entityName,
 Class<?> persistentClass,
 Set<Class<?>> interfaces,
 Method getIdentifierMethod,
 Method setIdentifierMethod,
 CompositeType componentIdType)
              throws HibernateException

Called immediately after instantiation of this factory.

Essentially equivalent to constructor injection, but contracted here via interface.

Parameters:

entityName - The name of the entity for which this factory should generate proxies.

persistentClass - The entity class for which to generate proxies; not always the same as the entityName.

interfaces - The interfaces to expose in the generated proxy; HibernateProxy is already included in this collection.

getIdentifierMethod - Reference to the identifier getter method; invocation on this method should not force initialization

setIdentifierMethod - Reference to the identifier setter method; invocation on this method should not force initialization

componentIdType - For composite identifier types, a reference to the type of the identifier property; again accessing the id should generally not cause initialization - but need to bear in mind <key-many-to-one/> mappings.

Throws:

HibernateException - Indicates a problem completing post instantiation initialization.

getProxy

HibernateProxy getProxy(Object id,
 SharedSessionContractImplementor session)
                 throws HibernateException

Create a new proxy instance

Parameters:

id - The id value for the proxy to be generated.

session - The session to which the generated proxy will be associated.

Returns:

The generated proxy.

Throws:

HibernateException - Indicates problems generating the requested proxy.
