org.springframework.jdbc.core.simple.ParameterizedSingleColumnRowMapper<T>

All Implemented Interfaces:

RowMapper<T>, ParameterizedRowMapper<T>

public class ParameterizedSingleColumnRowMapper<T>
extends SingleColumnRowMapper<T>
implements ParameterizedRowMapper<T>

ParameterizedRowMapper implementation that converts a single column into a single result value per row. Expects to operate on a java.sql.ResultSet that just contains a single column.

The type of the result value for each row can be specified. The value for the single column will be extracted from the ResultSet and converted into the specified target type.

Uses Java 5 covariant return types to override the return type of the SingleColumnRowMapper.mapRow(java.sql.ResultSet, int) method to be the type parameter T.
