public interface RowCallbackHandler
An interface used by JdbcTemplate for processing rows of a
 ResultSet on a per-row basis. Implementations of
 this interface perform the actual work of processing each row
 but don't need to worry about exception handling.
 SQLExceptions will be caught and handled
 by the calling JdbcTemplate.
 
In contrast to a ResultSetExtractor, a RowCallbackHandler
 object is typically stateful: It keeps the result state within the
 object, to be available for later inspection. See
 RowCountCallbackHandler for a usage example.
 
Consider using a RowMapper instead if you need to map
 exactly one result object per row, assembling them into a List.

void processRow(ResultSet rs)
                throws SQLException
next() on
 the ResultSet; it is only supposed to extract values of the current row.
 Exactly what the implementation chooses to do is up to it: A trivial implementation might simply count rows, while another implementation might build an XML document.
rs - the ResultSet to process (pre-initialized for the current row)
SQLException - if a SQLException is encountered getting
 column values (that is, there's no need to catch SQLException)|
