You can show the operations of classifiers with the full
signature of parameters along with the full package names in class
diagrams.
You must be in the C/C++ perspective and have
a diagram open in the diagram editor.
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.
