Hi,
I want to programmatically create the UML model for the following classes:
public class Bar {
public java.util.List<Foo> getFoos() {
}
}
Ideally, I want a diagram that contains only two classes Foo and Bar (and no java.util.List) in which getFoos() returns java.util.List<Foo>. However what I have right now, creates two classes Foo and List<Foo>. The relevant part in which I create the getFoos() method is shown below:
Package package = ...;
BasicEList paramNames = ...;
BasicEList paramTypes = ...;
String methodName = "getFoos";
String returnTypeStr = "java.util.List<Foo>";
Class returnType = package.create_owned_class(returnTypeStr, false);
Operation op = barClass.createOwnedOperation(methodName, paramNames, paramTypes, returnType);
As it can be seen, the problem with the code above is that I need to pass a returnType to createOwnedOperation and the only way I know of how to create that type is to create a class named List<Foo> which is not what I need. In reality, there are only three classes: List, Foo, and Bar.
How's it possible to accomplish this?

Hi
Use the UML Model Editor or Papyrus to create some small models and see
what they generate, then you can hand code the same thing.
