[Teneo] MappingBuilder customization [message #81906] Fri, 04 May 2007 09:43 Go to next message

Hello,

Is there a way to provide a custom MappingBuilder ? The aim is to be able
to overload getDefaultAnnotator(), and to change HibernateDefaultAnnotator
behavior.

A quick and dirty way to do this would be to remove the "final" in
MappingBuilder for the "static final MappingBuilder INSTANCE" statement.

Thanks,

Matthieu

Hi Matthieu,
Currently the only way is to override the mapEPackages method in the datastore. It is pretty simple:

/** Generate a hibernate mapping xml string from a set of epackages */
protected String mapEPackages() {
log.debug("Generating mapping file from in-mem ecore");
// DCB: Use Hibernate-specific annotation processing mechanism. This
// allows use of
// Hibernate-specific annotations.
final PersistenceOptions po = getPersistenceOptions();
paModel = MappingBuilder.INSTANCE.buildMapping(getEPackages(), po);
HibernateMappingGenerator hmg = new HibernateMappingGenerator(po);
return hmg.generateToString(paModel);
}

Probably it is nicer to also override getPamodel (there is no setPamodel yet).

Overall the extendability can be improved here. As you say providing a getter/setter around the
MappingBuilder.INSTANCE is an approach.
I will think about this and improve this for the next release. If you have other/more
ease-of-extendability ideas then let me know.
