Diapositive PPT

Example

For example, you want to perform some processing on classes and their attributes. In the metamodel, a class and its associated attributes is represented by the composition relation below:

If we wanted to traverse this class and all its attributes, we will declare:

visit_class_and_attributes(a_class : UML_CLASS;

visitor : TOP_DOWN_VISITOR) is

a_class.visit(visitor)

end -- visit_class_and_attributes
