The transformation of the generator model from the mapping model is described here. If you have looked at the *.gmfgen model that was produced in the tutorial, you'll notice that a quite a few things were created in the process.  A general overview of the transformation can be seen in the diagram below, which is followed by detail on each step.

From this diagram, you can see that the selected mapping model is first opened and validated.  The canvas is processed, followed by each node, and then each link.  Finally, the new generator model is saved and validated.

During the processing of the canvas, a GenModelMatcher is created and the EMF genmodel for the domain model is located. If you look at the generator [[Media:generation.png|model]] itself, you will see a large number of properties related to the canvas need to be set, in addition to the plug-in used to deploy our editor.  The names given to these properties are determined by a naming mediator. A DiagramRunTimeClass is selected and is the bridge we need to the GMF runtime notation model. In fact, if you open the *.gmfgen model in the EMF editor, you will see the notation model loaded, along with the domain model and ECore model.

During the processing of the nodes, another set of Gen* classes are initialized, in addition to *ModelFacet classes, which hold a reference to the domain model element represented by the node. Runtime notation model counterparts are selected, and if the node has an edit feature, the appropriate facet, GenNodeLabel, etc. are added. One of the more interesting aspects of the genmodel creation is found in how figures are generated by the FigureGenerator. At this stage, JET is used to produce the content of an inner class viewmap, contained in the *EditPart. Finally, tooling for the node is processed, as are child nodes and compartments.
