notesnet.dk - Eclipse Modelling Tools

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 is… what exactly?

Eclipse – The Sweets

ECLIPSE – The Mitsubishi Car

Eclipse – The Java IDE

Eclipse – The Tools Platform

Eclipse – The Application Platform

IBM Lotus Notes Version 8

The Eclipse Modeling Project and sub-projects

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

EMF
Eclipse Modeling Framework – is the base technology used to represent models
Logical models based on ER diagrams

Logical Model for NBS – Noware Bike Shop ~ Item Handlebars Frame Bike 0..* Wheel Gear Saddle

Logical Model for EMF ~ Named Element Model Element 0..1 Typed Element Classifier Structural Feature Attribute Reference Class Data Type 0..* 0..* 0..* type opposite superTypes 0..*

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

CDO
Connected Data Objects – is a distributed shared model framework for EMF models and meta models

XText
XText – is a text based editor framework for EMF models based on EBNF grammars
events doorClosed D1CL drawOpened D2OP … end resetEvents doorOpened end commands unlockPanel PNUL lockPanel PNLK … end state idle actions {unlockDoor lockPanel} doorClosed => active end state active drawOpened => waitingForLight lightOn => waitingForDraw end … grammar my.pack.SecretCompartments with org.eclipse.xtext.common.Terminals generate secretcompartment "http://www.eclipse.org/secretcompartment" Statemachine : 'events' (events+=Event)+ 'end' ('resetEvents' (resetEvents+=[Event])+ 'end')? 'commands' (commands+=Command)+ 'end' (states+=State)+; Event : name=ID code=ID; Command : name=ID code=ID; State : 'state' name=ID ('actions' '{' (actions+=[Command])+ '}')? (transitions+=Transition)* 'end'; Transition : event=[Event] '=>' state=[State];

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() ? "Internal" + genEnum.getName() : genModel.getImportedName(isEnum ? "org.eclipse.emf.common.util.Enumerator" : "org.eclipse.emf.common.util.AbstractEnumerator")%> { <%if (isEnum) {%> <%if (genEnum.getGenEnumLiterals().isEmpty()) {%> ; <%}else {%> <%for (Iterator<GenEnumLiteral> l = genEnum.getGenEnumLiterals().iterator(); l.hasNext(); ) { GenEnumLiteral genEnumLiteral = l.next(); %> /** * The '<em><b><%=genEnumLiteral.getFormattedName()%></b></em>' literal object. *  *  * @see #<%=genEnumLiteral.getEnumLiteralValueConstantName()%> * @generated * @ordered */ <%=genEnumLiteral.getEnumLiteralInstanceConstantName()%>(<%=genEnumLiteral.getValue()%>, "<%=genEnumLiteral.getName()%>", <%=Literals.toStringLiteral(genEnumLiteral.getLiteral(), genModel)%>)<%if (l.hasNext()) {%>,<%} else {%>;<%}%><%=genModel.getNonNLS()%><%=genModel.getNonNLS(2)%> <%}%> <%}%> <%}%>

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.
