Note: | Designer displays the ‡ symbol next to String, String List, and String table variables with a content type constraint only. Designer does not display the ‡ symbol next to Object and Object list variables with a specified Java class constraint. Object and Object lists with an applied Java class constraint have a unique icon. For more information about icons for constrained Objects, see Java Classes for Objects. |
