how to declare class friendship in class diagram

[Grigoris Dimitroulakos]

Hello
I want to model class friendship in EA8 so as to have the following result when I generate C++ code

class A{
  friend class B;
...
};

class B{
...
};

I have tried the following and it didn't work:
I used dependency relationship (class B ----(friend)--> class A ) stereotyped as "friend" or "permit". In that case the model had the dependency but the generated code is as
class A{
...
};

class B{
...
};

Thanks in advanced

I don't think friend relations are supported by the engineering process.

Most people consider it a bad practice, so you might want to rethink the need for friend relations.
