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

If true, the Classifier does not provide a complete declaration and can typically not be instantiated. An abstract classifier is intended to be used by other classifiers e.g. as the target of general metarelationships or generalization relationships.
Default value: FALSE

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)))
