Interface

Chapter 15 Working with IDL

Interface

You create a CORBA interface using a class with the <<CORBAInterface>> stereotype.

However, it is possible to design a CORBA interface using a PowerDesigner interface. When you create an interface, the <<CORBAInterface>> stereotype is automatically assigned. It is allowed to draw associations between these interfaces.

Interface properties mapping:

IDL concept	PowerDesigner implementation
Inheritance between interfaces	Generalization link between classes with <<CORBAInterface>> stereotype
Readonly attribute	readonly stereotype for attribute
Local interface	isLocal extended attribute set to True
Abstract interface	Abstract property selected in class property sheet
Interface declaration	Use inner link between <<CORBAInterface>> class and other items

Inner link
You can use an inner link to declare an item inner to another.

interface TestInterface {
   struct TestStruct {
      string member1;
   };

   attribute string StringA;
   attribute TestInterface::TestStruct MyStructAttr;
   void OperationA(inout TestStruct t, in string str);
   boolean OperationB(inout TestStruct t);
   
};

In this example, the composition link indicates that an attribute in TestInterface uses the other interface TestStruct as data type. The declaration inside the interface is performed with an inner link.
