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

Classifier If true, the Classifier does not provide a complete declaration and can
typically not be instantiated. An abstract classifier is intended to be
used by other classifiers e.g. as the target of general metarelationships
or generalization relationships.

RedefinableElement Indicates whether it is possible to further redefine a RedefinableElement.
If the value is true, then it is not possible to further redefine the RedefinableElement.
Note that this property is preserved through package merge operations;
that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false)
must be preserved in the resulting RedefinableElement of a package merge
operation where a RedefinableElement with isLeaf=false is merged with a
matching RedefinableElement with isLeaf=true: the resulting RedefinableElement
will have isLeaf=false. Default value is false.
Default value: FALSE

NamedElement A name which allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.

ElementConstraints:
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.
