I have a "medata driven appliation" that uses Hibernate.
I wanna read Hibernate mappings as input for metadata editor, I also have some other usage of it (eg. SQL DML).

I use SingleTableEntityPersister.getPropertyNames to read property names and getPropertyColumnNames to get SQL column names.

I figured out that I can use getKeyColumnNames to read keys SQL column names. But I was not able to find a method that tells me name of key properties?

Is there such method?
Can I get some where some better documentaion to Hibernate core APIs? (better than pure (poor) javadoc).

Thanks helping me.
