Useful for the typical case of one object per row in the database table. The number of entries in the results list will match the number of rows.

Note that a RowMapper object is typically stateless and thus reusable; just the RowMapperResultReader adapter is stateful.

A usage example with JdbcTemplate:

 JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);  // reusable object
 RowMapper rowMapper = new UserRowMapper();  // reusable object

 List allUsers = jdbcTemplate.query("select * from user", new RowMapperResultReader(rowMapper, 10));

 List userResults = jdbcTemplate.query("select * from user where id=?", new Object[] {id},
                                       new RowMapperResultReader(rowMapper, 1));
 User user = (User) DataAccessUtils.uniqueResult(userResults);

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.
