Abstract Class UML 2.5::RedefinableElement


A RedefinableElement is an element that, when defined in the context of a Classifier, can be redefined more specifically or differently in the context of another Classifier that specializes (directly or indirectly) the context Classifier.

Direct Superclasses: NamedElement

Direct Subclasses: Transition, State, Region, RedefinableTemplateSignature, Feature, ExtensionPoint, Classifier, ActivityNode, ActivityEdge

Signature: isRedefinitionContextValid(redefinedElement : RedefinableElement; ) : Boolean;
Description: The query isRedefinitionContextValid() specifies whether the redefinition contexts of this RedefinableElement are properly related to the redefinition contexts of the specified RedefinableElement to allow this element to redefine the other. By default at least one of the redefinition contexts of this element must be a specialization of at least one of the redefinition contexts of the specified element.
Expression: result = (redefinitionContext->exists(c | c.allParents()->includesAll(redefinedElement.redefinitionContext)))

Signature: isConsistentWith(redefiningElement : RedefinableElement; ) : Boolean;
Description: The query isConsistentWith() specifies, for any two RedefinableElements in a context in which redefinition is possible, whether redefinition would be logically consistent. By default, this is false; this operation must be overridden for subclasses of RedefinableElement to define the consistency conditions.
Expression: result = (false)
