Chapter 13. Example—Implementing a Model and Editor

Now that you are familiar with the capabilities of the EMF generator, it’s time to look at a more elaborate example. In this chapter we generate the ExtendedPO2 model, which includes some common real-world features that require special treatment when generating with EMF. They include:

  1. References that do not require proxy resolution.
  2. Volatile attributes and references.
  3. Custom data types.
  4. References with a restricted set of valid targets.

We show how these features can be implemented using a combination of generator control options and custom implementation in the generated classes. We then consider an alternative design, ExtendedPO3, which uses multiple packages to implement the same model. ...
