public interface PropertyMapping

Contract for all things that know how to map a property to the needed bits of SQL.

The column/formula fragments that represent a property in the table defining the property be obtained by calling either toColumns(String, String) or toColumns(String) to obtain SQL-aliased column/formula fragments aliased or un-aliased, respectively.

Note, the methods here are generally ascribed to accept "property paths". That is a historical necessity because of how Hibernate originally understood composites (embeddables) internally. That is in the process of changing as Hibernate has added CompositePropertyMapping
