Defining the Diagram Type

The main documentation of Graphiti is found in the Eclipse online help, which is also found in the Eclipse application (Help → Help Contents). If you don't have Graphiti yet, install it from the Juno release update site, Modeling category.

1. Read the Graphiti Introduction.
2. Create a new plugin named de.cau.cs.rtprak.login.turing.graphiti (like in previous tutorials, replace "login" by your login name) and add dependencies to the following plugins:
   
   • org.eclipse.graphiti
   • org.eclipse.graphiti.ui
3. Create a class TuringDiagramTypeProvider with superclass org.eclipse.graphiti.dt.AbstractDiagramTypeProvider.
4. Open plugin.xml and create an extension for org.eclipse.graphiti.ui.diagramTypes with a diagramType element:
   
   • id: de.cau.cs.rtprak.TuringDiagramType
   • type: turing
   • name: Turing Diagram Type
5. Create an extension for org.eclipse.graphiti.ui.diagramTypeProviders with a diagramTypeProvider element:
   
   • id: de.cau.cs.rtprak.login.TuringDiagramTypeProvider
   • name: Turing Diagram
   • class: name of the TuringDiagramTypeProvider class
6. Add a diagramType element to the diagramTypeProvider with id de.cau.cs.rtprak.TuringDiagramType.
7. Create a class TuringFeatureProvider with superclass org.eclipse.graphiti.ui.features.DefaultFeatureProvider.

8. Add the following constructor to TuringDiagramTypeProvider:

   Code Block
   theme Eclipse language java
   /** * Create a Turing diagram type provider. */ public TuringDiagramTypeProvider() { setFeatureProvider(new TuringFeatureProvider(this)); }
