Class UML 2.3::DataType

Description:

A data type is a type whose instances are identified only by their value. A data type may contain attributes to support the modeling of structured data types.

Direct Superclasses: Classifier

Direct Subclasses: PrimitiveType, Enumeration

Class Precedence List: DataType, Classifier, TemplateableElement, Type, PackageableElement, ParameterableElement, Namespace, RedefinableElement, NamedElement, Element

Properties:

ownedAttribute : Property (0 *); -- source DataType
ownedOperation : Operation (0 *); -- source DataType
attribute : Property (0 *); -- source Classifier
collaborationUse : CollaborationUse (0 *); -- source Classifier
feature : Feature (0 *); -- source Classifier
general : Classifier (0 *); -- source Classifier
generalization : Generalization (0 *); -- source Classifier
inheritedMember : NamedElement (0 *); -- source Classifier
isAbstract : Boolean (1 1); -- source Classifier
isFinalSpecialization : Boolean (1 1); -- source Classifier
ownedTemplateSignature : RedefinableTemplateSignature (0 1); -- source Classifier
ownedUseCase : UseCase (0 *); -- source Classifier
powertypeExtent : GeneralizationSet (0 *); -- source Classifier
redefinedClassifier : Classifier (0 *); -- source Classifier
representation : CollaborationUse (0 1); -- source Classifier
substitution : Substitution (0 *); -- source Classifier
templateParameter : ClassifierTemplateParameter (0 1); -- source Classifier
useCase : UseCase (0 *); -- source Classifier
templateBinding : TemplateBinding (0 *); -- source TemplateableElement
package : Package (0 1); -- source Type
visibility : VisibilityKind (1 1); -- source PackageableElement
owningTemplateParameter : TemplateParameter (0 1); -- source ParameterableElement
elementImport : ElementImport (0 *); -- source Namespace
importedMember : PackageableElement (0 *); -- source Namespace
member : NamedElement (0 *); -- source Namespace
ownedMember : NamedElement (0 *); -- source Namespace
ownedRule : Constraint (0 *); -- source Namespace
packageImport : PackageImport (0 *); -- source Namespace
isLeaf : Boolean (1 1); -- source RedefinableElement
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
ownedComment : Comment (0 *); -- source Element
ownedElement : Element (0 *); -- source Element
owner : Element (0 1); -- source Element

Constraints:

Signature: CMOF_14_3_28() : Boolean;
Description: 14.3 [28] A Property owned by a DataType can only be typed by a DataType.
Expression: ownedAttribute.type.oclIsKindOf(DataType)

Operations:

Signature: inherit(inhs : NamedElement; ) : NamedElement;
Description: The inherit operation is overridden to exclude redefined properties.
The OCL used here is not normative.
Editor's notes: reject not excluding. The operation Classifier.inhertedMember, redefined to eliminate non-progressing recursion, does not use inherit. Something similar should occur here. But I haven't written it yet. See Class.inherit, Classifier.inherit. Needs further study!
Expression: result = inhs->reject(inh | ownedMember->select(oclIsKindOf(RedefinableElement))->select(redefinedElement->includes(inh)))
Original: result = inhs->excluding(inh | ownedMember->select(oclIsKindOf(RedefinableElement))->select(redefinedElement->includes(inh)))
