UML syntax: Generalization

[ronaldtse]

Generalization

• Def.- A generalization is an abstraction principle applied to hierarchically structure the semantics of a model.
• A generalization is a relationship between a general classifier and a special classifier, where the special classifier adds more features (specialization) and behaves in a way compatible to the general classifier.

Notation & Semantics

• A generalization or specialization classifies features hierarchically; features with general meinings are allocated to general classifiers and special features are allocated to classifiers that area subclassifiers of general classifiers.
• The features of superclassifiers are passed on to their subclassifiers (inheritance).
• So a subclassifier has the features specified for it and the features of its superclassifiers (or overwrite them).

Proposal:

class GeomFigure
class Circle {
  generalizes GeomFigure
}
class Rectangle {
  generalizes GeomFigure
}
class Triangle {
  generalizes GeomFigure
}
