Let’s assume I have a class called MyClass with an attribute called MyAttribute and a method called MyMethod(). Inside that method I’d like to have a variable called MyVariable. I’d like to set the value of MyVariable to “MyVariable” and MyAttribute to “MyAttribute” inside the call to MyMethod(). How can I do this in a Collaboration Diagram?

I can’t find any info of this kind on the internet and the book I’m studying from (Applying UML and Patterns) is very vague in the details.

Thanks

    IMHO UML is not meant to contain such details. In my understanding, a collaboration diagram is supposed to show how different object call each other’s methods in order to achieve a certain goal, not what is happening inside a specific method.

    But if you really, really want to record such details (e.g. because it is important to understand how the program logic works), you can add (pseudo)code in a comment box or something similar. Here is an example.
