public interface RowMapper
An interface used by JdbcTemplate for mapping rows of a
 ResultSet on a per-row basis. Implementations of this
 interface perform the actual work of mapping each row to a result object,
 but don't need to worry about exception handling.
 SQLExceptions will be caught and handled
 by the calling JdbcTemplate.
 
Typically used either for JdbcTemplate's query methods
 or for out parameters of stored procedures. RowMapper objects are
 typically stateless and thus reusable; they are an ideal choice for
 implementing row-mapping logic in a single place.
 
Alternatively, consider subclassing
 MappingSqlQuery from the
 jdbc.object package: Instead of working with separate
 JdbcTemplate and RowMapper objects, you can build executable query
 objects (containing row-mapping logic) in that style.

Object mapRow(ResultSet rs,
              int rowNum)
              throws SQLException
next() on
 the ResultSet; it is only supposed to map values of the current row.
rs - the ResultSet to map (pre-initialized for the current row)rowNum - the number of the current row
SQLException - if a SQLException is encountered getting
 column values (that is, there's no need to catch SQLException)|
