How to find replacements for deprecated API in BO WebI 4.0 Report Engine Java SDK

For my web application, I need to use the following classes:

1. ReportStructure
2. ReportElement
3. ReportContainer
4. ReportDictionary
5. ReportExpression

I got the API reference guide for WebI Report Engine Java SDK from http://scn.sap.com/docs/DOC-27465 and when I look up these classes, all of them are marked as deprecated but no replacement classes are specified. I also went through the deprecated link provided but even here, i could not see any information on what classes replace these deprecated ones.

I would appreciate pointers to where I can find this information.
