Chapter 17 Working with Eclipse

Eclipse EMF overview

The Ecore model will be used to generate the implementation classes. There are several ways to define an Ecore model:

• Using Ecore XMI file
• Using annotated Java classes
• Using a Rose model

In this section, we use the Ecore XMI file to generate an Ecore model from a PowerDesigner Class Diagram.

• The Ecore XMI format consists of:
• A .genmodel file for all the packages
• A .ecore file for each package

From the definition of the Ecore model, the EMF code generator generates interfaces and implementation classes that provide: class factory, metadata management, getters/setters, object navigation, serialization/deserialization, undoable commands, notifications, Eclipse plugin for creating and modifying instance data.
