Showing operation signatures of classifiers

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 Filters > Show Signature.
Note: If the Show Parent Name option is also enabled, the parameter types are displayed with the full package name.
