Does anyone have an example of a fairly verbose ResultTransformer implementation that they can share? I'm trying to implement a Nested Set transformer, based on code provided by Christian Bauer in the project JIRA, but his implementation won't quite work for me as it stands now (excellent, well-documented code, though). The ResultTransformer interface specifies two methods: - List transformList(List collection) - Object transformTuple(Object[] tuple, String[] alias) I do not understand the purpose of transformList(): most implementations are one line long, simply returning whatever was passed to it. I have a partial understanding of transformTuple(). The tuple corresponds to the resultset (i.e. tuple[0] equates (bad term there, I know) to resultSet.getXXX(0)). The alias array corresponds to any aliases defined in the SQL. Thanks for any help. Jason
