Interface RowMapper

public interface RowMapper

An interface used by Executor 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.

java.lang.Object mapRow(java.sql.ResultSet rs,

                        throws java.sql.SQLException

rowNum - the number of the current row

Returns:

the result object for the current row

Throws:

java.sql.SQLException - if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)
