GMF

GMF Overview

“The Eclipse Graphical Modeling Framework (GMF) provides a

generative component and runtime infrastructure for developing

graphical editors based on EMF and GEF[1].”

Significantly reduces cost of DSL tooling

GMF is part of Eclipse Modeling Project

GMF-generated solutions proved by .ecore diagram editor

[1] GEF is an MVC-based framework to create graphical editors

Building diagram editor with GMF,

basic steps

Design EMF domain meta-model

Create graphical representations for diagram nodes/links

Define diagram structure and generate code

?

GMF architecture: GMF Tooling

Set of models to define diagram editor - capturing

graphical, tooling and meta-modeling aspects.

Extensible code generator, capable to customize

generated code to match specific requirements

Metamodel (Ecore)

The root element (i.e.,

Application) of the

metamodel is hidden for

illustrating purpose

There are bidirectional

references

Graphical definition

Is used to define the figures, nodes, links,

etc. that you will display on your diagram

Sirius

Created in the context of complex systems modeling

Collaboration of people with different concerns

For each concern, there is a viewpoint

A bit of Sirius history

Sirius

Based on GMF, EMF and the Eclipse

Platform

Allows one to define multi-view workbenches

including tables, trees or diagrams

Diagram

The content of the Diagram Description is

mostly made of mappings, and their

associated tools. In addition, it can also

contain filters and layout configuration

information.

Diagram

Mapping Maps semantic elements onto some

graphical notation

General mapping description

Domain class: is the type of semantic element

which are represented by the diagram

Defines what diagrams are activated from existing

diagrams

Style: the graphical aspect of the mapping

Expression

Expression Restricts the number of model elements to consider before creating

graphical elements

Is evaluated starting from a context element

Should return a set (possibly empty) of elements in the semantic

model

Keywords used in expressions

OCL

Self makes reference to the domain class of the diagram

EMF

eGet

Sirius

Features makes reference to the container of the current domain class of a

mapping

Types of expressions:

Semantic

Source/Target finder

Mapping

Types of mapping

Node

Container

Edge

Conditional

Node

Is used to represent model elements

graphically as atomic elements, i.e., elements

which can not contain other elements

maps to

Node

Node

Container Is used to represent model elements

graphically as containers, which can contain

sub-elements (including other containers,

recursively)

maps to

Container

Container

Edge

Is used to define connections between

diagram elements.

Two kinds of edges:

Relation-Based Edges

Domain-Based Edges

Relation-Based Edges

Are used to represent a reference between model

elements such as containment, simple or complex

reference

There is no direct

semantic element

but a complex

reference

maps to

[self.cartographyElements-> collect(r|r.migRelations) -

>select(r|r.dest.parentModule.eGet('name') <>self.name) ->

collect(c|c.dest.parentModule)/]

Relation-based edge

Domain-Based Edges

Are used when a semantic model element (instead

of simply a reference) exists to represent the relation

itself

maps to

Domain-based edge

Conditional style

Makes it possible to support different

graphical aspects for a single mapping

Conditional

Filter

A diagram can define any number of filters,

which can be enabled or disabled

dynamically by the user to show or hide some

elements of a diagram

Example:

Filter by kind-of ElementRelation

Layout Algorithms to perform an automatic layout of

all the graphical elements on a diagram

Two kind-of algorithms:

Default

E.g., Ordered Tree Layout

Customized

the default algorithm does not fit your needs, you can

configure some parameters or request for alternate

algorithms (currently only one) directly inside the

viewpoint

Tools

Are used to define the behavior of your

modeler

Two types of tool:

Tools that appear in the diagram’s palette (e.g. a

tool to create a new node)

Tools that are automatically invoked when the

user performs certain operations (e.g. a delete

tool which is triggered when the user deletes an

element from the diagram)

Case study: Thales

Thales is a French multinational company

that designs and builds electrical systems

and provides services for

the aerospace, defense, transportation and s

ecurity markets

Case study: Thales

Thales has integrated and extended several standards

such as MARTE [1], UML, SysML [2], etc. and added

specific graphical editors to support:

Operational analysis

Functional analysis

Logical architecture

Physical architecture

Non functional constraints

Non functional trade-off

Transition to software or hardware

[1] profile to develop Real-Time and Embedded systems

[2] profile for specifying, analyzing, designing, and verifying complex systems that

may include hardware, software, information, personnel, procedures, and facilities

Functional analysis (requirements)

MARTE multi-view workbench

What practicioners say…

For Jean-Luc Voirin, one of the main benefit

of this approach is to avoid exhaustive

modelling. With the multi-viewpoint tooling,

the architects can adjust modelling effort on

major engineering issues
