Class UML 2.4.1::Actor

Description:

An actor specifies a role played by a user or any other system that interacts with the subject.

Direct Superclasses: BehavioredClassifier

Direct Subclasses:

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

Properties:

classifierBehavior : Behavior (0 1); -- source BehavioredClassifier
interfaceRealization : InterfaceRealization (0 *); -- source BehavioredClassifier

The set of InterfaceRealizations owned by the BehavioredClassifier. Interface realizations reference the Interfaces of which the BehavioredClassifier is an implementation.

Constraints:

Signature: must_have_name() : Boolean;
Description: An actor must have a name.
Expression: name->notEmpty()

Signature: associations() : Boolean;
Description: An actor can only have associations to use cases, components and classes. Furthermore these associations must be binary.
The OCL used here is not normative.
Editor's notes: Actor.ownedAttribute is not defined.
Expression: true
Original: self.ownedAttribute->forAll ( a | (a.association->notEmpty()) implies ((a.association.memberEnd.size() = 2) and (a.opposite.class.oclIsKindOf(UseCase) or (a.opposite.class.oclIsKindOf(Class) and not a.opposite.class.oclIsKindOf(Behavior))))

Operations:

No additional operations.
