Why ? How ?


Why ? How ?

• Small development team

• Fast prototyping

• Recurring kinds of application

Constraints

Issue© Anyware Technologies-All Right Reserved


• Model Driven Approach

• Meta Modeling

• Generation and genericframework

Solution

•Create the same kind of application for differentdomains

•Ex: a graphical editor, a form

Need

Recurring kind of application© Anyware Technologies-All Right Reserved


•Pragmatic Model Driven

•Progressive commoditization

•Progressive improvement of the generator

Solution

Definition of a generator

• Creation of the domain specific language (DSL)

►Ex: UML, Autosar, Petri Net… genealogy

• Definition of the target



►Ex: graphical editor framework, web framework

• Creation of a model describing this target

►Ex: graphical editor metamodel, CRUD application metamodel

• Creation of the generator

• Don’t try to generate everything !

Eclipse Modeling Framework - EMF


Eclipse Modeling Framework - EMF

EMF

• Framework used to create tools based on a model

• Ecore is used to create meta models.

• Ecore provides :



►Simple and reverse references

►Composition

►Types

• Close to UML class diagram.

EMF

• EMF bounds the modeling and development worlds :

► It transforms models into java

►Allows to use the model in your application

►Gives tools to increase development productivity



►Gives tools to increase development productivity

• Open-source

• Strong and tested technology (used since 2002)

EMF Generation

GenModel

Java ModelDisplay and edit basic functions

Graphical Modeling Framework - GMF


Graphical Modeling Framework - GMF

GMF

• Ease the development of graphical editor for models

• Runtime

►Framework with a lot of common features for graphical model

editors



editors

• Generator

►Tool to generate a graphical editor from a model and the editor

definition


Model to Text - xPand


Model to Text - xPand

xPand

• Designed specifically for text generation

►OO template engine supporting template polymorphism

►Template Varibility using AOP

►Editor with Code Completion and Syntax



►Editor with Code Completion and Syntax

►Highlighting

• Debugger

xPand

• Example of template:

«IMPORT model»«DEFINE file FOR SourceComponentClass»«FILE project.name.toLowerCase() + "/" + name + ".java"-»package «project.name.toLowerCase()»;

public class «name» extends ComponentClass {




«IF methods.select(m | m.kind.toString() == "EVENT").size > 0»public void receiveEvent(int inputEventMethod, Object value) {

«FOREACH methods.select(m | m.kind.toString() == "EVENT") AS m-»// TODO handle Event: " + «m.name.toUpperCase()»:

«ENDFOREACH-»}

«ENDIF»}«ENDFILE»«ENDDEFINE»
