After migration, when you use the UML-to-Java transformation capabilities of the Rational® UML modeling product, the code elements that were not tagged during migration are not modified based on changes made in the UML source model.
For example, if you delete or rename a UML class and a Java class exists with the same (fully qualified) name, but without an @generated tag, when you run a UML-to-Java transformation against that UML model, the Java class is not modified in the Java source file. However, you can manually change this behavior.To manually change the XDE Java code element tagging behavior:
Add an @generated annotation to the element in the source file. This tag tells the UML-to-Java transformation that it now has jurisdiction over the Java element; changes made to the UML model are applied to the Java class in the source code. For more details, see the online help for the UML-to-Java transformation.
