Class UML 2.3::DurationConstraint

Description:

A duration constraint is a constraint that refers to a duration interval.

Direct Superclasses: IntervalConstraint

Direct Subclasses:

Class Precedence List: DurationConstraint, IntervalConstraint, Constraint, PackageableElement, ParameterableElement, NamedElement, Element

Properties:

firstEvent : Boolean (0 2); -- source DurationConstraint
specification : DurationInterval (1 1); -- source DurationConstraint
constrainedElement : Element (0 *); -- source Constraint
context : Namespace (0 1); -- source Constraint
visibility : VisibilityKind (1 1); -- source PackageableElement
owningTemplateParameter : TemplateParameter (0 1); -- source ParameterableElement
templateParameter : TemplateParameter (0 1); -- source ParameterableElement
clientDependency : Dependency (0 *); -- source NamedElement
name : String (0 1); -- source NamedElement

The name of the NamedElement.

nameExpression : StringExpression (0 1); -- source NamedElement
namespace : Namespace (0 1); -- source NamedElement
qualifiedName : String (0 1); -- source NamedElement
ownedComment : Comment (0 *); -- source Element

The Comments owned by this element.
{composite}
Subsets: Element.ownedElement

ownedElement : Element (0 *); -- source Element

The Elements owned by this element.
{composite, readonly}
Derived union with sources: (ownedComment, nameExpression)
Opposite: Element.owner

owner : Element (0 1); -- source Element

Constraints:

Signature: first_event_multiplicity() : Boolean;
Description: The multiplicity of firstEvent must be 2 if the multiplicity of constrainedElement is 2. Otherwise the multiplicity of firstEvent is 0.
The OCL used here is not normative.
Editor's notes: Added endif.
Expression: if (constrainedElement->size() =2) then (firstEvent->size() = 2) else (firstEvent->size() = 0) endif
Original: if (constrainedElement->size() =2) then (firstEvent->size() = 2) else (firstEvent->size() = 0)

Operations:

No additional operations.
