All Implemented Interfaces:

XAResource, Mapper, RowMapper

public class JDBCMapper
extends JDBCRowMapper
implements Mapper

A JDBCMapper maps objects to and from a JDBC database. It is specific to a given database connection, as it computes statements.

The JDBCMapper does the mapping according to the policy defined by a Model, and generates SQL statements recorded in the SQLInfo.
