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
required : Interface (0 *); -- source Port

References the interfaces specifying the set of operations and receptions that the classifier expects its environment to handle via this port. This association is derived according to the value of isConjugated. If isConjugated is false, required is derived as the union of the sets of interfaces used by the type of the port and its supertypes. If isConjugated is true, it is derived as the union of the sets of interfaces realized by the type of the port and its supertypes, or directly from the type of the port if the port is typed by an interface.
{readonly, derived}
The spec does not provide a function to compute this derived property!

Constraints:

Signature: port_destroyed() : Boolean;
Description: When a port is destroyed, all connectors attached to this port will be destroyed also.
Expression: true

Description: Port.aggregation must be composite.
Expression: true

Signature: default_value() : Boolean;
Description: A defaultValue for port cannot be specified when the type of the Port is an Interface
Expression: true

Operations:

No additional operations.
