Nested classes
In ABAP OOP, we can nest classes in three ways:
- A class as an attribute of the class
- Inheritance
- Using interfaces
Interfaces are not really a full class. This is due to the fact that, in interfaces, we have only a definition of a class without any implementation. This is important because interfaces in ABAP allow us to implement multi-inheritance. However, we'll turn to that in a moment, in the Inheritance and Interfaces section.
All examples will be shown as a global class created in SE24.
