Generate the GMF fragment with Dawn
Before you start make sure that you have the following components installes:
We will examine the Dawn Codegen by using the Acore example from the Dawn SDK. In the beginning we need to get all necessary model files. Open the Plug-ins View (Window-->Show View-->Others) as shown in the picture below.
Now select the plug-in org.eclipse.emf.cdo.dawn.examples.acore and import it as soure plug-in
Generate the EMF model code
Now we will generate the code as you would do it for a normal project. This means the model code, the edit plug-in and GMF diagram plug-in.
Now your workspace contains the plug-ins: the one containing the model code, the edit plug-in and the diagram plug-in. Now right click the the gmf gen model an examine the context menu. You will see an additional entry called "Generate Dawn Genmodel"
Running this will create a new file called acore.dawngenmodel. This model contains specific information for the Dawn generator.
For example it allows to configure the names of the extension classes generated by dawn.
Generate the fragment
In a final step now right click the Dawn genmodel and choose "Generate Dawn GMF Fragment" from the context menu.
Now a fragment will be created containing all the specific extensions for your diagram.
