Constraints Applied to Variables
Designer displays small symbols next to a variable icon to indicate the constraints applied to the variable. Designer displays variables in the following ways:
Variable | Constraint status | Variable Properties |
| Required field. | The Required property is set to True. |
| Optional field. | The Required property is set to False. |
| Required field with content type constraint | The Content type property specifies an IS schema or XML schema. |
| Optional field with content type constraint | The Required property is set to False and the Content type property specifies an IS schema or XML schema. |
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.
