Class UML 2.3::Class

Description:

Class has derived association that indicates how it may be extended through one or more stereotypes. Stereotype is the only kind of metaclass that cannot be extended by stereotypes.

Direct Superclasses: EncapsulatedClassifier, BehavioredClassifier

Direct Subclasses: Stereotype, Node, Component, Behavior, AssociationClass

Class Precedence List: Class, EncapsulatedClassifier, StructuredClassifier, BehavioredClassifier, Classifier, TemplateableElement, Type, PackageableElement, ParameterableElement, Namespace, RedefinableElement, NamedElement, Element

Properties:

extension : Extension (0 *); -- source Class
isAbstract : Boolean (1 1); -- source Class
isActive : Boolean (1 1); -- source Class
nestedClassifier : Classifier (0 *); -- source Class
ownedAttribute : Property (0 *); -- source Class
ownedOperation : Operation (0 *); -- source Class

The operations owned by the class.
{composite, ordered}
Subsets: Classifier.feature, Namespace.ownedMember
Opposite: Operation.class

ownedReception : Reception (0 *); -- source Class
superClass : Class (0 *); -- source Class
ownedPort : Port (0 *); -- source EncapsulatedClassifier
ownedConnector : Connector (0 *); -- source StructuredClassifier
part : Property (0 *); -- source StructuredClassifier

References the properties specifying instances that the classifier owns by composition. This association is derived, selecting those owned properties where isComposite is true.
{readonly, derived}
The spec does not provide a function to compute this derived property!

Constraints:

Signature: CMOF_14_3_18() : Boolean;
Description: 14.3 [18] Class must not be active see also: https://sites.google.com/site/metamodelingantipatterns/catalog/mof/class-is-active
Expression: not isActive

Signature: CMOF_14_3_15() : Boolean;
Description: 14.3 [15] Only one member attribute of a Class may have isId=true. see also: https://sites.google.com/site/metamodelingantipatterns/catalog/mof/class-has-more-than-one-id
Expression: self->closure(general)->union(self)->attribute->asSet()->select(p:Property | p.isID)->size() < 2

Signature: CMOF_14_3_10a() : Boolean;
Description: 14.3 [10] The following properties must be empty Class::nestedClassifier Property::qualifier see also: https://sites.google.com/site/metamodelingantipatterns/catalog/mof/class-has-nested-classifier
Expression: nestedClassifier->isEmpty()

Signature: passive_class() : Boolean;
Description: A passive class may not own receptions.
Expression: not self.isActive implies self.ownedReception.isEmpty()

Operations:

Signature: inherit(inhs : NamedElement; ) : NamedElement;
Description: The inherit operation is overridden to exclude redefined properties.
The OCL used here is not normative.
Editor's notes: reject not excluding
Expression: result = inhs->reject(inh | ownedMember->select(oclIsKindOf(RedefinableElement))->select(redefinedElement->includes(inh)))
Original: result = inhs->excluding(inh | ownedMember->select(oclIsKindOf(RedefinableElement))->select(redefinedElement->includes(inh)))
