An interface used by JdbcTemplate for mapping returned result sets. Implementations of this interface perform the actual work of mapping rows, but don't need to worry about exception handling. SQLExceptions will be caught and handled correctly by the JdbcTemplate class.

Typically used either for JdbcTemplate's query methods (with RowMapperResultReader adapters) or for out parameters of stored procedures. RowMapper objects are typically stateless and thus reusable; they are ideal choices 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 have executable query objects (containing row-mapping logic) there.
