The Address Book sample includes a simple Class model in which the behaviors of Class Operations have been written in Alf. The model includes a Class diagram showing an Address Book Class that contains zero or more instances of an Entry Class.
To see the Alf code for an Operation of a Class, open the Alf editor window (select Windows > Alf) and select the Operation in the Address Book Class diagram. The Alf code for the Operation will then appear in the window.
Running a model with Alf exercises the functionality of the Address Book model. This activity should be run with the Animation speed slider set to its maximum (rightwards) position.
