Contract for run-time, proxy-based lazy initialization proxies.
Author:Gavin King
/** * Contract for run-time, proxy-based lazy initialization proxies. * * @author Gavin King */
public interface ProxyFactory {
Called immediately after instantiation of this factory.

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

Create a new proxy instance
Params:
  • id – The id value for the proxy to be generated.
  • session – The session to which the generated proxy will be associated.
Throws:
Returns:The generated proxy.
