Chapter 17 Working with VB .NET

Class

You design a VB .NET class using a class in PowerDesigner. VB .NET classes can contain events, variables, constants, methods, constructors and properties.

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.
  

Public MustInherit Class Customer
   Private Name As Char
   Private ID As Integer
End Class

• 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
