Class HibernateDescriptorDecorator

java.lang.Object
  org.tynamo.hibernate.services.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

                                    DescriptorFactory descriptorFactory,

Method Detail

decorate

public TynamoClassDescriptor decorate(TynamoClassDescriptor descriptor)

Specified by:

decorate in interface DescriptorDecorator

decoratePropertyDescriptor

protected TynamoPropertyDescriptor decoratePropertyDescriptor(Class type,
                                                              org.hibernate.mapping.Property mappingProperty,

                                                              TynamoClassDescriptor parentClassDescriptor)

sortPropertyDescriptors

protected List sortPropertyDescriptors(Class type,
                                       List propertyDescriptors)

The default way to order our property descriptors is by the order they appear in the hibernate config, with id first. Any non-mapped properties are tacked on at the end, til I think of a better way.

Parameters:

propertyDescriptors -

Returns:

findMetadata

protected org.hibernate.metadata.ClassMetadata findMetadata(Class type)
                                                     throws MetadataNotFoundException

Find the Hibernate metadata for this type, traversing up the hierarchy to supertypes if necessary

Parameters:

type -

Returns:

Throws:

MetadataNotFoundException

notAHibernateProperty

protected boolean notAHibernateProperty(org.hibernate.mapping.Component componentMapping,
                                        TynamoPropertyDescriptor propertyDescriptor)

Checks to see if a property descriptor is in a component mapping

Parameters:

componentMapping -

propertyDescriptor -

Returns:

true if the propertyDescriptor property is in componentMapping

notAHibernateProperty

protected boolean notAHibernateProperty(org.hibernate.metadata.ClassMetadata classMetaData,
                                        TynamoPropertyDescriptor descriptor)

Parameters:
