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.

Executing the TestAddressBook Activity (using CST) exercises the functionality of the Address Book model. This activity should be run with the Animation speed slider set to its maximum (rightwards) position.
