Class UML 2.5::ExtensionEnd

Description:

An extension end is used to tie an extension to a stereotype when extending a metaclass. The default multiplicity of an extension end is 0..1.

Direct Superclasses: Property

Constraints:

No additional constraints.

Operations:

Signature: lowerBound() : Integer;
Description: The query lowerBound() returns the lower bound of the multiplicity as an Integer. This is a redefinition of the default lower bound, which normally, for MultiplicityElements, evaluates to 1 if empty.
Expression: result = (if lowerValue=null then 0 else lowerValue.integerValue() endif)
