Activity diagram: manipulation with Eclipse [message #819411]

Hello,
Can I handle UML diagrams with Eclipse?
I credit my UML activity diagram, and I noticed that Eclipse has converted it to xml.I tried to manipulate the xml code with a java class. For that I install JDOM API that allows me to manipulate XML data. Until now all is well. Is my approach correct, and is there another way to manipulate the UML diagram?
Any comments will be very interesting for me because this is the first time I use Eclipse.
Thank you.

Hi

No. Your approach is completely wrong.

All models are XML files, or rather XMI files.

The Eclipse Modeling Prpject is all about tools that process these
models effectively.

A couple that you could play with are:
select your file and Open With->Sample Ecore Model Editor
select your file and Open With->UML Model Editor

Papyrus can edit your diagrams. Tx tools can change them.

Hello,
First of all, thank you for your replay.
I create my activity diagram using Papyrus.
And then I select it and open it with UML Model Editor.
But i don't understand what i can do with it.
I can explain more my problem: i want to manipulate my diagram programmatically , means par example to know how many Action has the diagram.
Hope I could explain my problem properly.
Thank you.
Best Wishes.

Hi

You could for instance write a Model transformation that at some point
perhaps

Action.allInstances()->size()

You could invoke the above in the OCL Console.

You could load your UML model as a Resource and write Java or Xtend code
to process it.

Hello Ed,

I am interested in solving the same problem.

To what documentation I should refer to achieve this task?

What is the difference between the previous approach (load the UML as a resource and working in Java) and a model transformation approach? (like the ones provided by xtext, epsilon, acceleo?)

Thank you for your help
Best,
Alfredo

Hi

The UML2 project priovides documentation.
There are many Java books and tutorials.
The Xtend project provides documentation.

A model transformation differs because
a) your models are loaded and saved for you
b) the programming language is optimised for models and so is more
compact and better checked.

Xtext does many good things but model transformation is normally model
to something, so Xtext's text to model is not usually regarded as model
transformation.

Thank you.
Right now I have only found one example in the FAQs of the UML2 wiki to load a uml resource in a stand alone application (sorry the forum is stopping me to post the link)

and a section in this book
EMF: Eclipse Modeling Framework, 2nd Edition

if you have other pointers (more code examples?) this is really helpful for me.
Most of the other tutorials that I have found are about code generation which is not
my focus.

Now is clear, thank you

HI

Have you looked at the Getting started in the built-in UML documentation.

HI
Have you looked at the Getting started in the built-in UML documentation.

Found. However to my understanding in the Getting Started it only covers the generation of class diagrams using Java. There are examples with other diagrams? I am interested in state diagrams, activity diagrams and sequence diagrams. I did not found them in the built-in help

Thank you again for your quick replies and help
