In contrast to a {@link ResultSetExtractor}, a RowCallbackHandler object is typically stateful: It keeps the result state within the object, to be available for later inspection. See {@link RowCountCallbackHandler} for a usage example.
Consider using a {@link RowMapper} instead if you need to mapexactly one result object per row, assembling them into a List. @author Rod Johnson @author Juergen Hoeller @see JdbcTemplate @see RowMapper @see ResultSetExtractor @see RowCountCallbackHandler
