How to signal object instantiation in a Collaboration/Communication Diagram?

Question

I'd like to know how to translate the following line of code to a Collaboration Diagram:

Food food = new Food("abc", 123);

I know that I can call an Food's method using the following notation:

 MyStaticMethod()
----------------------> --------
                        |      |
                        | Food |
                        |      |
                        --------

being that equivalent to

Taste taste = Food.MyStaticMethod();

and

 MyInstanceMethod()
----------------------> ---------------
                        |             |
                        | food : Food |
                        |             |
                        ---------------

is equivalent to

food.MyInstanceMethod();

but how do I signal that I want to call a given constructor on Food?

Thanks

Answer 1

When wanting to call a static method, generally we denote the class by <<metaclass>>. So, as answer for the first shown diagram, to call a static method called MyStaticMethod on Food, we'd do:

 MyStaticMethod()
----------------------> ---------------------
                        |   <<metaclass>>   |
                        |        Food       |
                        |                   |
                        ---------------------

Also, people generally denote the constructor method by create().
