ABAP Objects: Object-Oriented Programming for ABAP (englisch)

Get started with an introduction to object-oriented ABAP and a comparison with procedural ABAP. You’ll learn about class components before exploring key class design concepts that will help you create new classes and improve your use of existing classes. The instructor will show you how to implement inheritance, polymorphism, and interfaces using code examples in the Eclipse IDE. Code samples will be available for download after the course.

Topics

• Classes
• Attributes
• Constructors
• Methods
• Inheritance
• Polymorphism
• Interfaces
• Abstract classes
• Abstract methods

Take a close look at class-based error handling and testing! You’ll master the structure of exception classes and then learn to define and implement them. Next, you’ll explore unit testing with ABAP Unit. The instructor will explain test-driven development and teach you how to define unit test classes, execute unit tests, and evaluate test results using the Eclipse IDE. Code samples will be available for download after the course.

Topics

• Exception classes
• Raising and catching exceptions
• ABAP Unit
• Test-driven development
• Assertions in ABAP Unit
• Managing dependencies
• Executing tests
• Evaluating test results

Level-up your OOP skills with design patterns! Master the correct use of factory, singleton, and composite patterns to solve common application design problems that you might encounter in your daily work. The instructor will use real-world examples and code samples to show you how to implement each pattern. Then apply your knowledge of ABAP Objects to the ALV object model (SAP List viewer) to display datasets like lists, tables, and tree structures. Code samples will be available for download after the course.

• Factory pattern
• Singleton pattern
