Examples of org.springframework.jdbc.core.RowCallbackHandler

org.springframework.jdbc.core.RowCallbackHandler
An interface used by {@link JdbcTemplate} for processing rows of a{@link java.sql.ResultSet} on a per-row basis. Implementations ofthis interface perform the actual work of processing each row but don't need to worry about exception handling. {@link java.sql.SQLException SQLExceptions} will be caught and handledby the calling JdbcTemplate.
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
