Eclipse Modeling Tools - 2010-10-26

Eclipse is probably best known as a first class Java IDE, but it is so much more than that.In this talk, I will present the different tools that makes up the Eclipse Modeling Project from the simple (EMF) to the very complex (QVT/O). The emphasis will be on the immediately useful techniques with plenty of demonstrations.

Eclipse Modeling Project

“The Eclipse Modeling Project focuses on the evolution and promotion of model-based development technologies within the Eclipse community by providing a unified set of modeling frameworks, tooling, and standards implementations.”

Relevant Modeling Sub-Projects

Administrative Projects EMF, EMFT, GMP, GMT, MDT, M2M, M2T, and TMF

Some Relevant Technical Projects EMF – Eclipse Modeling Framework – is the base technology used to represent

models OCL – Object Constraint Language – allows you to specify advanced constraints

and invariants CDO – Connected Data Objects – is a distributed shared model framework for

EMF models and meta models XText – is a text based editor framework for EMF models based on EBNF

grammars GMF – Graphical Modeling Framwork – is a graphics based editor framework for

EMF models JET – Java Emitter Templates – is a JSP like language for generating Java code

from a model Xpand – is a high-level template language used to translate models to text QVT/O – Operational QVT (Query/View/Transformation) – is a very, very high-

level language for model to model transformations Teneo – is a database persistency solution for EMF using Hibernate or EclipseLink

OCL

Object Constraint Language – allows you to specify advanced constraints and invariants

E.g. Item price is positive:

Context Item: inv self.price > 0

It has exactly one Saddle: Context Bike: inv self.items->select(i : Item | i.oclIsKindOf(Saddle))->size()

== 1

Can be tested using the interactive console

Can be embedded directly in Ecore

XText

XText – is a text based editor framework for EMF models based on EBNF grammars

GMF

Graphical Modeling Framwork – is a graphics based editor framework for EMF models

In itself also a number of models that describe how objects and graphical items and tools maps

JET

Java Emitter Templates – is a JSP like language for generating Java code from a model

public <%if (isEnum) {%>enum<%} else {%>final class<%}%> <%=genEnum.getName()%> <%if (isEnum) {%>implements<%} else {%>extends<%}%> <%=genModel.isSuppressEMFMetaData() && !genModel.isSuppressInterfaces() ?

Xpand

Xpand – is a high-level template language used to translate models to text

Expandable and type-safe Has an aspect-based extension system to allow users to extend current templates

«DEFINE Root FOR data::DataModel» «EXPAND Entity FOREACH entity»«ENDDEFINE»

«DEFINE Entity FOR data::Entity» «FILE name + ".java"» public class «name» { «FOREACH attribute AS a» // bad practice private «a.type» «a.name»; «ENDFOREACH» } «ENDFILE»«ENDDEFINE»

Eclipse.dk – The Danish Eclipse Society

Eclipse.dk was created in Marts 2007 as a meeting place for everyone interested in the Eclipse (www.eclipse.org) platform.

The purpose of Eclipse.dk is as follows: To promote the knowledge of Eclipse in Denmark. To create networks amongst danish Eclipse-users and developers. To build knowledge on Eclipse in Denmark, especially

In danish institutes of higher education. Between danish companies developing applications based on Eclipse.

Create and maintain a web site on Eclipse for danish users – eclipse.dk.

Strengthen the relations between danish and international Eclipse-users and organizations.

The eclipse.dk society has members representing not only vendors of Eclipse-based products and services, but also users of the platform and representatives from institutions of higher education.
