Examples of Joinable

org.apache.openjpa.jdbc.meta.Joinable
Represents a value that can be joined to. Any column that a user joins to must be "owned" by an entity that implements this interface. The system maps columns to joinables to be able to decompose oids and field values into individual join values on a per-column basis. This allows us to support joins to only some of the columns of a mapping, and to be loose with the ordering of foreign key columns relative to the ordering of the joined-to columns. Having a separate interface for joinables also allows us to perform tricks such as a vertically-mapped application identity subclass transparently transforming columns of its foreign key to the corresponding primary key fields in the base class. @author Abe White
org.hibernate.persister.entity.Joinable
Anything that can be loaded by outer join - namely persisters for classes or collections. @author Gavin King
