A UML Union is a standard Modeler Class item that has the «CORBAUnion» stereotype applied to it.
Create a Union from the Model or a Package: right-click the Model or Package, point to New, point to IDL Profile, and then click Union. After creating the Union, you must apply the «CORBAUnion» stereotype to it.
The Union uses child Attributes to define its discriminant, cases and the default:
• An Attribute that is stereotyped by the «CORBASwitch» stereotype is generated as the discriminant.
• An Attribute that is stereotyped by the «CORBACase» stereotype is generated as a case.
• An Attribute that is stereotyped by the «CORBADefault» stereotype is generated as the default case.
