You can use the pop-up code editor from within domain modeling
class diagrams to view or directly edit Java classifiers,
such as classes and interfaces.
About this task
You can also use domain modeling class diagrams to modify Java classifiers and to add fields or methods
to classes or interfaces.
When you add fields or methods to classes
or interfaces, qualified names will be added for type proposals in
packages if the Java Editor Code Assistant's default Add
import instead of qualified name preference option is
cleared. Otherwise, import declarations will be added automatically.
