Class Instance Specification--General Tab

Figure 76 Class Instance Specification--General Tab

Refer to the descriptions earlier in this chapter or in the Introduction to Specifications chapter for information on the specification elements not covered in the following section.

Class

The class the element belongs to is displayed here. The default class for a newly created element is (Unspecified). If you specify an object's class in the Object Specification, the class name must identify a class defined in the model, or you may create a new class.

To create a new class through the Object Specification, click the scroll arrow to the right of the Class field. A list box will display all the possible class selections, including <New>. Double-click <New>. A Class Specification dialog box is displayed. Enter the information regarding the new class.

If you delete a class from the model after you have associated it with one or more objects, the class name is enclosed in parentheses. If you re-create the class or create a new class with the same name, the object becomes an instance of the new class.

You can set this field only through the dialog box.
