I recently discovered
prefuse (better late than never) and the various examples made me imagine an ATL use case: creating several points of view from a given UML2 model. Let's see what it consists on, using for example a model standing for the ATL Virtual Machine structure.
So, a pop-up dynamically launch a set of ATL transformation on a model:
The Tree View shows a containment tree of classes and packages:
The Graph View shows an association sub-net (with a lot of parameters... useless in our case but quite fun):
Those views are quite simplistic - I didn't change original prefuse demos - but could be extended to display more data from the input model.
This example, and other advanced model transformation techniques will be explained in the
EclipseCon 2009 ATL tutorial.
Sometimes never is better. For example non-SWT UI does not look good in Eclipse, so you may want to discover Zest. http://www.eclipse.org/gef/zest/
RépondreSupprimerI agree, and Zest seems to be as powerful as its API is simple to use. But that's the point: this demo is focused on the ATL transformation between UML and GraphML/TreeML, so I don't want to write Java code (excepted to launch ATL transformations).
RépondreSupprimerPrefuse directly brings views from xml graph files, so it fitted my current need. I understand that you're bored to see people like me using prefuse in an "Eclipse context" ;-) , but be sure that if I find a way to - simply - load GraphML (EMF model/xmlfile) into Zest, I would rewrite my ATL demo...
Eugene, thanks for shout-out about Zest.
RépondreSupprimerWilliam, we can hack this at EclipseCon. I used ATL for model transformations for a number of targets (birt, Zest, JFace, etc...) during my PhD. I have some EMF models for all these things.
Ok, I will be pleased to see that !
RépondreSupprimerThe images are broken in this post :-(
RépondreSupprimerImages are back... thanks for reporting it !
RépondreSupprimerCan I display UML diagrams that look like UML diagrams using Perfuse?
RépondreSupprimerFor the purpose of this example I used the simpliest features of prefuse, but maybe the diagrams could be enhanced a bit. I don't think you can reach an "UML-like" look anyway.
RépondreSupprimerThe goal here was more to make an very specific point of view of a given concept : containment, inheritance...
This was done 3 years ago, maybe prefuse has evolved since, or there is a better API somewhere :-)
