You can show the operations of classifiers with the full
signature of parameters along with the full package names in class
diagrams.
You must have a diagram open in the diagram editor
and the classifiers’ operation compartments must be visible. Ensure that
you have not set preferences to filter or hide operations.
Note: If you do not show operation signatures, the parameters
and return types do not appear in the diagram.
To show the operation signature of a classifier, in the
diagram editor, right-click a classifier; then click .
Note: If the Show Parent Name option
is also enabled, the parameter types are displayed with the full package
name.
