Entities as collections in sequence diagram

[bouhor]

Hi,
I have a question:
How to say, in the sequence diagram, that an entity is a collection (map ,set ..etc)
like this:


I'm using EA 7.5 corporate

Help me please.

Create a class with the name 'Map<Livre>'.

Set that as the classifier for your lifeline.

Actually the correct UML way would be to create a parametrized template class for you generic Map<T> class and instantiate it with the Livre class.
There is some support for this in EA, but I haven't tried to use it yet.

I made the suggestion that I did because I know parametrized class information will not show up on the sequence diagram.

Simon,

So that would just be a visualization issue then.
So it depends on what you want to do with the model.
If it is mainly for presentation purposes then the "map<Livre>" solution is the best.
If you want a technically correct model (to do code generation or something like that) you better go with the parametrized class solution.
