public interface Ref
The data structure identified by an instance of Ref is held in the
database, so the data is not necessarily read and converted
into a Java object until getObject is called. However, if
the database supports the Ref type, it is not typically
necessary to get the underlying object before using it in a method call -
the Ref object can be used in place of the data structure.
A Ref object is stored into the database using the
PreparedStatement.setRef(int, Ref) method.
