It's not safe. If you have to return a value from "handleRow",
introduce a private variable.
private Person newPersonFromHandleRow;
public void handleRow(Object valueObject)
{
Person person = (Person) valueObject;
newPersonFromHandleRow = MyFactory.createSubClassObject( person );
}
But out of curiosity, why would you use "handleRow" to return a single
object? RowHandler is intended to handle situations where number of
rows being returned from the query is too large to be held into a list.
