UML Xor Constraint
The XOR constraint connector is depicted as a dashed line. It connects two elements (e.g. associations, classes) in the diagram. The meaning of XOR constraint is that only of the interconnected elements can be used at a time.
How to add an XOR constraint to the diagram
You can insert an XOR constraint to the diagram this way:
- Click on the Constraint Connector tool in the Common group in the toolbox
