An interface used by
JdbcTemplate for mapping rows of a
java.sql.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.
java.sql.SQLException SQLExceptions will be caught and handled
by the calling JdbcTemplate.

Implementations must implement this method to map each row of data
in the ResultSet. This method should not call next() on
the ResultSet; it is only supposed to map values of the current row.
Parameters: rs - the ResultSet to map (pre-initialized for the current row) Parameters: rowNum - the number of the current row the result object for the current row throws: java.sql.SQLException - if a SQLException is encountered gettingcolumn values (that is, there's no need to catch SQLException)
