Creating Generalization Sets

A Generalization Set enables you to specify the relationship of a group of Generalizations. Each Generalization is a binary relationship that relates a specific Classifier to a more general Classifier (for example, from a Class to its Superclasses). Each Generalization Set defines a particular set of Generalization relationships that describe the way in which a general Classifier (or superclass) can be divided using specific subtypes.

(If you do not select the checkbox, the constraint is regarded as {incomplete} although this is not displayed in the label).

5

Consider the 'Is Disjoint' checkbox. If you select this, on a diagram the constraint {disjoint} will be added to the label of each generalization that is a member of the set. (If you do not select the checkbox, the constraint is regarded as {overlapping} although this is not displayed in the label).

In the 'Is Member' column, select the checkbox against each child subtype that is part of this Generalization set.
