public interface RowHandler

Event handler for row by row processing.

The RowHandler interface is used by the SqlMapSession.queryWithRowHandler() method. Generally a RowHandler implementation will perform some row-by-row processing logic in cases where there are too many rows to efficiently load into memory.

Example:

 sqlMap.queryWithRowHandler ("findAllEmployees", null, new MyRowHandler()));
