## org.hibernate.proxy
Interface ProxyFactory

All Known Implementing Classes:
  Dom4jProxyFactory, JavassistProxyFactory, MapProxyFactory

    public interface ProxyFactory

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

Method Summary
`HibernateProxy` | `getProxy(Serializable id, SessionImplementor session)` Create a new proxy instance
`void` | `postInstantiate(String entityName, Class persistentClass, Set interfaces, Method getIdentifierMethod, Method setIdentifierMethod, CompositeType componentIdType)` Called immediately after instantiation of this factory.

Method Detail

### postInstantiate

    void postInstantiate(String entityName,
                         Class persistentClass,
                         Set 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 mappings.
  Throws:
    `HibernateException` - Indicates a problem completing post instantiation initialization.

### getProxy

    HibernateProxy getProxy(Serializable id,
                            SessionImplementor 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.
