Inheritance Graph
Illustrates generalizations between classes.
Fusion describes two types of inheritance:
- Joint Inheritance - Any number of subclasses can inherit the properties of the superclass.
- Disjoint Inheritance - The subclasses create the superclass and only the subclasses named explicitly in the diagram can inherit the properties of the superclass.
How to create a Fusion Inheritance Graph
Use Rumbaugh's object diagram notations.
