Class UML 2.4.1::Component

Description:

In the namespace of a component, all model elements that are involved in or related to its definition are either owned or imported explicitly. This may include, for example, use cases and dependencies (e.g. mappings), packages, components, and artifacts.A component represents a modular part of a system that encapsulates its contents and whose manifestation is replaceable within its environment.

Constraints:

Signature: no_packaged_elements() : Boolean;
Description: component nested in a Class cannot have any packaged elements.
Expression: (not self.class->isEmpty()) implies self.packagedElement->isEmpty()

Signature: no_nested_classifiers() : Boolean;
Description: A component cannot nest classifiers.
Expression: self.nestedClassifier->isEmpty()

Operations:

Signature: usedInterfaces(classifier : Classifier; ) : Interface;
Description: Utility returning the set of used interfaces of a component.
The OCL used here is not normative.
Editor's notes: supplierDependency not defined.
Expression: Set{}
Original: result = (classifier.supplierDependency-> select(dependency|dependency.oclIsKindOf(Usage) and dependency.supplier.oclIsKindOf(interface)))-> collect(dependency|dependency.supplier)

Signature: required.1() : Interface;
Description: Missing derivation for Component::/required : Interface
The OCL used here is not normative.
Editor's notes: realizedInterfaces() not RealizedInterfaces(), and it is also a variable here. Needs investigation.
Expression: Set{}
Original: result = let usedInterfaces : Set(Interface) = UsedInterfaces(self), realizingClassifiers : Set(Classifier) = Set{self.realizingClassifier}->union(self.allParents().realizingClassifier), allRealizingClassifiers : Set(Classifier) = realizingClassifiers->union(realizingClassifiers.allParents()), realizingClassifierInterfaces : Set(Interface) = allRealizingClassifiers->iterate(c; rci : Set(Interface) = Set{} | rci->union(UsedInterfaces(c))), ports : Set(Port) = self.ownedPort->union(allParents.oclAsType(Set(EncapsulatedClassifier)).ownedPort), usedByPorts : Set(Interface) = ports.required in usedInterfaces->union(realizingClassifierInterfaces) ->union(usedByPorts)->asSet()

Signature: realizedInterfaces(classifier : Classifier; ) : Interface;
Description: Utility returning the set of realized interfaces of a component.
The OCL used here is not normative.
Editor's notes: I removed a open paren here somewhere.
Expression: result = classifier.clientDependency-> select(dependency|dependency.oclIsKindOf(Realization) and dependency.supplier.oclIsKindOf(Interface))-> collect(dependency|dependency.client)
Original: result = (classifier.clientDependency-> select(dependency|dependency.oclIsKindOf(Realization) and dependency.supplier.oclIsKindOf(Interface)))-> collect(dependency|dependency.client)

Signature: provided.1() : Interface;
Description: Missing derivation for Component::/provided : Interface
The OCL used here is not normative.
Editor's notes: realizedInterfaces() not RealizedInterfaces(), and it is also a variable here. Needs investigation.
Expression: Set{}
Original: result = let realizedInterfaces : Set(Interface) = RealizedInterfaces(self) , realizingClassifiers : Set(Classifier) = Set{self.realizingClassifier}->union(self.allParents().realizingClassifier), allRealizingClassifiers : Set(Classifier) = realizingClassifiers->union(realizingClassifiers.allParents()) , realizingClassifierInterfaces : Set(Interface) = allRealizingClassifiers->iterate(c; rci : Set(Interface) = Set{} | rci->union(RealizedInterfaces(c))) , ports : Set(Port) = self.ownedPort->union(allParents.oclAsType(Set(EncapsulatedClassifier)).ownedPort) , providedByPorts : Set(Interface) = ports.provided in realizedInterfaces->union(realizingClassifierInterfaces) ->union(providedByPorts)->asSet()
