Class UML 2.3::DurationConstraint
Description:
A duration constraint is a constraint that refers to a duration interval.Direct Superclasses: IntervalConstraintDirect Subclasses: Class Precedence List: DurationConstraint, IntervalConstraint, Constraint, PackageableElement, ParameterableElement, NamedElement, ElementProperties:

qualifiedName : String (0 1); -- source NamedElement A name which allows the NamedElement to be identified within a hierarchy
of nested Namespaces. It is constructed from the names of the containing
namespaces starting at the root of the hierarchy and ending with the name
of the NamedElement itself.{readonly, derived}

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.
