Abstract Class UML 2.3::StructuralFeature
Description:
By specializing multiplicity element, it supports a multiplicity that specifies valid cardinalities for the collection of values associated with an instantiation of the structural feature.Direct Superclasses: MultiplicityElement, TypedElement, FeatureDirect Subclasses: PropertyClass Precedence List: StructuralFeature, MultiplicityElement, TypedElement, Feature, RedefinableElement, NamedElement, ElementProperties:
isReadOnly : Boolean (1 1); -- source StructuralFeature isOrdered : Boolean (1 1); -- source MultiplicityElement isUnique : Boolean (1 1); -- source MultiplicityElement lower : Integer (0 1); -- source MultiplicityElement lowerValue : ValueSpecification (0 1); -- source MultiplicityElement upper : UnlimitedNatural (0 1); -- source MultiplicityElement upperValue : ValueSpecification (0 1); -- source MultiplicityElement type : Type (0 1); -- source TypedElement featuringClassifier : Classifier (0 *); -- source Feature isStatic : Boolean (1 1); -- source Feature
isLeaf : Boolean (1 1); -- source RedefinableElement Indicates whether it is possible to further redefine a RedefinableElement.
If the value is true, then it is not possible to further redefine the RedefinableElement.
Note that this property is preserved through package merge operations;
that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false)
must be preserved in the resulting RedefinableElement of a package merge
operation where a RedefinableElement with isLeaf=false is merged with a
matching RedefinableElement with isLeaf=true: the resulting RedefinableElement
will have isLeaf=false. Default value is false.Default value: FALSE
redefinedElement : RedefinableElement (0 *); -- source RedefinableElement redefinitionContext : Classifier (0 *); -- source RedefinableElement clientDependency : Dependency (0 *); -- source NamedElement name : String (0 1); -- source NamedElement nameExpression : StringExpression (0 1); -- source NamedElement namespace : Namespace (0 1); -- source NamedElement qualifiedName : String (0 1); -- source NamedElement visibility : VisibilityKind (0 1); -- source NamedElement ownedComment : Comment (0 *); -- source Element ownedElement : Element (0 *); -- source Element The Elements owned by this element.{composite, readonly}
