Class HibernateDescriptorDecorator

java.lang.Object
  org.tynamo.hibernate.decorators.HibernateDescriptorDecorator

All Implemented Interfaces:

DescriptorDecorator

public class HibernateDescriptorDecorator
extends Object
implements DescriptorDecorator

This decorator will add metadata information. It will replace simple reflection based TynamoPropertyTynamoPropertyDescriptors with appropriate Hibernate descriptors

Background... TynamoDescriptorService operates one ReflectorDescriptorFactory - TynamoDescriptorService iterates/scans all class types encountered - ReflectorDescriptorFactory allocates property descriptor instance for the class type - TynamoDescriptorService decorates property descriptor by calling this module HibernateDescriptorDecorator - HibernateDescriptorDecorator caches the decorated property descriptor into a decorated descriptor list - decorated descriptor list gets populated into class descriptor for class type - TynamoDescriptorService finally populates decorated class descriptor and it's aggregated list of decorated property descriptors into it's own list/cache of referenced class descriptors
