Using EMF, models may be created and the java code for them is automatically created.
Furthermore, EMF gives the possibility to generate code for an editor using the eclipsee model. This editor may be launched as an Eclipse application, which uses the defined model and gives the user the possibility to create model instances.
GMF extends this functionality: Notation symbols may be matched to model types and associations. Based on the definition of notation symbols and the matching, java gmff for a graphic editor can be generated.
Launching it as an eclipse application, the model instances can now be created as a diagram. The model will be a very basic business process model, which consists only of events and process steps.
The goal will be to have a graphical editor, which may be used to create a business process using events and process steps. Basically this editor will be created without writing a single line of code. Here are the sources, which I used for creating the example.
First of all we need to use the Eclipse IDE. In the following example I am using the Juno distribution, but other distributions should do fine as well. Install the following plugins:. Next step is to create an EMF Ecore model. The model folder should now contain two files: On opening the ecorediag file an editor will show, eclipwe lets us create the model in a graphical environment. ProcessShapes gmv connected using a Sequence. In the next step, be sure, that the model folder is selected and give a name for the EMF generator model, i.

After, we need to select the EMF. The basepackage needs to be set to the project name and the folder, in which the model resides. Now everything is set to generate the model and the edit code.
Now edlipse may start with the graphical part, defining the notation symbols and map them to the model.

The following view should open:. After being successful, the. This means, mgf events will be represented by Ellipses and processSteps by Rectangles. The GMFGraph model should now look like this:. The file should look like this:. Leave the following two views also like they are. The last view shows the mapping and should look like this:.
We need to make some manual amendments, i. Now you are able to create a very basic process diagram, which consists of events and processSteps. Your email address will not be published.
