Tagged value dialog box

Tagged values

Tagged values are used to refine the semantics of existing classes, through the addition of new attributes defined in a use case.

Tagged values are typed and can have values.

A tagged value is expressed as follows: "{tagged value_name:Qualifier(p1,p2,p3)}".

The "Tagged value" dialog box contains one standard tab, the "Properties" tab.

· "Type": This field is used to select the type of the tagged value from the dropdown scrolling list.

· "Parameters": This zone is used to add, remove or modify parameters associated with the tagged value. The buttons in this dialog box are used as follows:

v : This button is used to add a new parameter. When you click on this button, the parameter entry zone is activated, and you can directly enter the parameter.

v : This button is used to remove a parameter from the tagged value in question.
