| DbBeanFetcher | | public class DbBeanFetcher extends DbRowProcessor (Code) | | This class allows a
ResultSet to be easily processed into bean

Multiple instances can be collected into a list when processing an
entire
ResultSet , or as a single bean instance can be retrieved for
one row of a
ResultSet . The default behavior is to not collect
instances.
