Doug,

Yes, modifying the factory to do additional initialization for newly created objects would make sense. An alternative would be to attach a listener which detects creation/addition of a new car and responds by creating/adding the necessary tires.

If I were to create a simple object that has a containment association with an N..N value (as shown in the "simple" model below), is there a proper place in which I can modify the generated code such that the contained objects are always of the correct number?

In this example, could I modify one of the factories such that a "Car" object is always created with 4 "Tire" child objects?

TIA

Please try to avoid cross posting the same question to so many different newsgroups.

Hi All,

I'm working on a project that will extend UML2Tools. I need help for:

a) use existing uml2tools functionality (primarily the class and component diagram at the moment)

b) extend uml2tools functionality to add elements described using stereotypes (for instance a class element already stereotyped with a custom stereotype). these components will be added to the palette so that the they can be dragged and dropped onto the editor.

c) not alter uml2tools code so that future versions of uml2tools can be used without affecting the extension and not requiring recoding of the extension.

This should obviously take place in a new plugin. I've looked at the examples in the help files (like helloworld etc) but have not worked out how to extend plugins like uml2tools.

Please could someone describe how I should set up a plugin to do all this?

thanks in advance,

regards,
