Abstract Class UML 2.4.1::StructuralFeature

Description:

A structural feature is a typed feature of a classifier that specifies the structure of instances of the classifier.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: TypedElement, MultiplicityElement, Feature

Direct Subclasses: Property

Class Precedence List: StructuralFeature, TypedElement, MultiplicityElement, Feature, RedefinableElement, NamedElement, Element

Properties:

isReadOnly : Boolean (1 1); -- source StructuralFeature
type : Type (0 1); -- source TypedElement
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
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
