Interface RowMapper

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

BeanPropertyRowMapper, ColumnMapRowMapper

public interface RowMapper
extends java.io.Serializable

An interface used by JdbcQueryCallbackWrapper for mapping rows of a ResultSet on a per-row basis. Typically used for JdbcQueryCallbackWrapper's factory method org.hdpagination.dataaccess.support.jdbc.JdbcQueryCallbackWrapper#newInstance(). RowMapper objects are typically stateless and thus reusable; they are an ideal choice for implementing row-mapping logic in a single place.

Method Summary

Method Detail

processRow

java.lang.Object processRow(java.sql.ResultSet rs)
                            throws java.sql.SQLException

Parameters:

Returns:

the result object for the current row

Throws:

java.sql.SQLException - - if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)
