Class UML 2.3::Interface

Description:

Since an interface specifies conformance characteristics, it does not own detailed behavior specifications. Instead, interfaces may own a protocol state machine that specifies event sequences and pre/post conditions for the operations and receptions described by the interface.

Direct Superclasses: Classifier

Direct Subclasses:

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

Properties:

nestedClassifier : Classifier (0 *); -- source Interface
ownedAttribute : Property (0 *); -- source Interface
ownedOperation : Operation (0 *); -- source Interface
ownedReception : Reception (0 *); -- source Interface
protocol : ProtocolStateMachine (0 1); -- source Interface
redefinedInterface : Interface (0 *); -- source Interface
attribute : Property (0 *); -- source Classifier
collaborationUse : CollaborationUse (0 *); -- source Classifier
feature : Feature (0 *); -- source Classifier
general : Classifier (0 *); -- source Classifier
generalization : Generalization (0 *); -- source Classifier
inheritedMember : NamedElement (0 *); -- source Classifier
isAbstract : Boolean (1 1); -- source 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.
Default value: FALSE

Constraints:

Signature: visibility() : Boolean;
Description: The visibility of all features owned by an interface must be public.
Expression: self.feature->forAll(f | f.visibility = #public)

Operations:

No additional operations.
