Interface ProxyFactory

All Known Implementing Classes:

ByteBuddyProxyFactory, MapProxyFactory

public interface ProxyFactory

Contract for run-time, proxy-based lazy initialization proxies.

Method Summary

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

Method Detail

postInstantiate

void postInstantiate(java.lang.String entityName,
                     java.lang.Class persistentClass,
                     java.util.Set<java.lang.Class> interfaces,
                     java.lang.reflect.Method getIdentifierMethod,
                     java.lang.reflect.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 mappings.

Throws:

HibernateException - Indicates a problem completing post instantiation initialization.

getProxy

HibernateProxy getProxy(java.io.Serializable 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.
