Class UML 2.3::Port

Description:

A port has an associated protocol state machine.

Direct Superclasses: Property

Direct Subclasses:

Class Precedence List: Port, Property, StructuralFeature, MultiplicityElement, DeploymentTarget, ConnectableElement, ParameterableElement, TypedElement, Feature, RedefinableElement, NamedElement, Element

Properties:

isBehavior : Boolean (1 1); -- source Port
isConjugated : Boolean (1 1); -- source Port
isService : Boolean (1 1); -- source Port
protocol : ProtocolStateMachine (0 1); -- source Port
provided : Interface (0 *); -- source Port
redefinedPort : Port (0 *); -- source Port

A port may be redefined when its containing classifier is specialized. The redefining port may have additional interfaces to those that are associated with the redefined port or it may replace an interface by one of its subtypes.
