Bi-directional one-to-many association using generics

General Questions/Discussions
1

Hi,

I have a one to many bi-directional association beween a class Category and Product (using JDK 1.5 generics). Here is the simplified code where we can see that a Category has many Products and a Product has a parent Category :

public class Category {

    private Long id;
    private String name;
    private String description;
    private List<Product> products;
}

public class Product {

    private Long id;
    private String name;
    private Category category;
}

When I reverse this code into VP-UML (SDE for Intellij Idea 3.3 sp3) I have the following class diagram :

Category <------ Product

When I really want this :

Category --------*- Product

I know that generics are recognized by VP-UML, is there any specific thing to do ? I can’t find any information.

Thanks,

Antonio

Thank you very much Jick. I really apreciate. I’m writing a book and using Visual-Paradigm for my UML diagrams so it will be really good to have this feature. Let me know.

Hum, it looks like my license for 2.3 doesn’t work for 3.0. I’ m going to try with a temporary key.
