Modelling overriding interface operations

[apabil]

Hello,

I am trying to model the overriding of an interface operation. The goal is to generate Java-Code out of the model. The operation-code should look like this:

Code: [Select]

button.addClickHandler(new ClickHandler(){
 public void onClick(ClickEvent event){
  do_something();
 }
});

I can't find out how to model the override of the onClick-operation in my activity diagram.
Is this possible with EA?

Thanks in advance,

I found a simple solution.

By creating a subclass which implements the interface, it is possible to override the onClick-operation directly in the subclass. The method body can than be described by a activity diagram related to the onClick-operation in the subclass. In the activity diagram in the main class it is just necessary to create a instance of the subclass.
 
Best regards,
