Cocoa UML Class Model
UML class diagrams show each class as a named box connected to other classes with inheritance, interface and aggregation relationships. The relationships between classes form natural clusters that can be easily identified and mapped to diagrams within MacA&D. A large system is represented by several diagrams of clustered classes.
In these diagrams, we've shown just the class name and relationships. Class attributes and class operations could also be shown. In fact, configuration options allow details like data types, access and arguments to be included on the diagram.
