Visual Basic 2005 Classes

PowerDesigner models Visual Basic 2005 classes as standard UML classes, but with additional properties.

For information about creating and working with classes, see Classes (OOM).

The following specific classes are also supported in PowerDesigner:

MustInherit class is equivalent to an abstract class. To design this type of class you need to create a class and select the Abstract check box in the General tab of the class property sheet.

NotInheritable class is equivalent to a final class. To design this type of class, you need to create a class and select the Final check box in the General tab of the class property sheet.
Public NotInheritable Class FinalClass Private At1 As Object Private At2 As Object End Class
