Collaboration occurrence

[ulb]

Hi NG

I bought a book (in german "UML 2.0 Das umfassende Handbuch" from Christoph Kecher) including examples modelled with EA. There I've seen a collaboration diagram with a collaboration occurrence.

How can I create a collaboration occurence in EA. I havn't found any possibility to create a CO directly or indirectly.

Many thanks
Erny

See "Communication Diagram" in EA's help. You'll find an explanation on how to create these diagrams. N.B. Communication is the new term for Collaboration...

The only diagramm with collaboration occurence I found in help of EA was "Composite Structure Diagramm"

But I didn't find any explanation how to create a collaboration occurence.

With CO I mean nearly the same as collaboration. Not the dependency with the stereotype <<occurence>>.

Any help is welcome.

Thanx, Erny

Hmmm. http://www.sparxsystems.com.au/EAUserGuide/index.html?colloccurrence.htm

And yes, you'd probably start with a 'composite structure' diagram, and add the required elements.

This http://www.sparxsystems.com.au/EAUserGuide/index.html?collaboration2.htm tells you about a collaboration. [Accessing pages directly like this 'breaks' the links in the page - go back to the index if necessary.]

The 'occurrence' bit is like saying an instance of the collaboration.

Many thanks !!  

The key was, --> Collaboration occurence is an instance of a collaboration.

Would be great, if this could be added to the help.

The key is in noting the diagram in the EA help, and the line "The following example uses an occurrence, 'NWServer', of the collaboration 'Install".

See how the diagram element is labelled NWServer:Install - this is just like when you have an instance of a class(ifier), which gets labelled Instance:Classifier
