There's more to ABAP than procedural programming. If you're ready to leap into the world of ABAP Objects—or are already there and just need a refresher—then this is the book you've been looking for. Thanks to explanations of basic concepts and practical examples that show OOP in action, you'll find answers to questions you didn't even know you had. Highlights include:- Working with objects- Encapsulation and implementation hiding- Object initialization and cleanup- Inheritance - Polymorphism - Component-based design- Exceptions- ABAP Unit- ALV object model- Object Services- BOPF
