Method Detail

toArray

java.lang.Object[] toArray(java.sql.ResultSet rs)
                    throws java.sql.SQLException

                 throws java.sql.SQLException

Create a JavaBean from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.

Parameters:

rs - ResultSet that supplies the bean data

type - Class from which to create the bean instance

Returns:

the newly created bean

Throws:

java.sql.SQLException - if a database access error occurs

toBeanList

java.util.List toBeanList(java.sql.ResultSet rs,
                          java.lang.Class type)
                   throws java.sql.SQLException

Create a List of JavaBeans from the column values in all ResultSet rows. ResultSet.next() should not be called before passing it to this method.

Parameters:

rs - ResultSet that supplies the bean data

type - Class from which to create the bean instance

Returns:

A List of beans with the given type in the order they were returned by the ResultSet.

Throws:

java.sql.SQLException - if a database access error occurs

toMap

java.util.Map toMap(java.sql.ResultSet rs)
             throws java.sql.SQLException

Create a Map from the column values in one ResultSet row. The ResultSet should be positioned on a valid row before passing it to this method. Implementations of this method must not alter the row position of the ResultSet.

Parameters:

rs - ResultSet that supplies the map data
