Class UML 2.5::Port

Description:

A Port is a property of an EncapsulatedClassifier that specifies a distinct interaction point between that EncapsulatedClassifier and its environment or between the (behavior of the) EncapsulatedClassifier and its internal parts. Ports are connected to Properties of the EncapsulatedClassifier by Connectors through which requests can be made to invoke BehavioralFeatures. A Port may specify the services an EncapsulatedClassifier provides (offers) to its environment as well as the services that an EncapsulatedClassifier expects (requires) of its environment. A Port may have an associated ProtocolStateMachine.

Operations:

Signature: required.1() : Interface;
Description: Derivation for Port::/required
Expression: result = (if isConjugated then basicProvided() else basicRequired() endif)

Signature: provided.1() : Interface;
Description: Derivation for Port::/provided
Expression: result = (if isConjugated then basicRequired() else basicProvided() endif)

Signature: basicRequired() : Interface;
Description: The union of the sets of Interfaces used by the type of the Port and its supertypes.
Expression: result = ( type.oclAsType(Classifier).allUsedInterfaces() )

Signature: basicProvided() : Interface;
Description: The union of the sets of Interfaces realized by the type of the Port and its supertypes, or directly the type of the Port if the Port is typed by an Interface.
Expression: result = (if type.oclIsKindOf(Interface) then type.oclAsType(Interface)->asSet() else type.oclAsType(Classifier).allRealizedInterfaces() endif)
