UML syntax: Redefinable element

[ronaldtse]

Notation & Semantics

• In UML, overwriting (redefining) features is controlled by the metamodel class RedefinableElement.
• All metamodel classes that are subclasses of RedefinableElement can be overwritten in a generalization relationship.
• The overwriting element stores a reference to the overwritten element.
• For attributes, this relationship also transpires in the notation by the property string {redefines }
