Using Rose

The Abstract check box identifies a class that serves as a base class. An abstract class defines operations and states that will be inherited by subclasses. This field corresponds to the abstract class adornment displayed inside the class icon. To toggle the abstract adornment, select or clear the abstract check box in the Class Specification. When you click Abstract and you view the model in Booch notation, the abstract class adornment is displayed in the lower left corner of the class icon. You can change the abstract class adornment only through the specification. The Abstract field is inactive for metaclasses, class utilities, parameterized class utilities, and instantiated class utilities. Formal Arguments In the Parameterized Class or Parameterized Class Utility Specification, the formal, generic parameters declared by the class or class utility are listed. In the Instantiated Class or Instantiated Class Utility Specification, the actual arguments that match the generic parameters of the class being instantiated are listed.
