1 Component Development for the Component Description Framework (CDF) Training Dr.-Ing. Ulrich Dinger

2 Bildung ist die Fähigkeit, fast alles anhören zu können, ohne die Ruhe zu verlieren oder das Selbstvertrauen. Robert Frost

3 Overview General concepts and terms The aloXerv MOT-language The Ecore modeling language The Component Description Framework and the CDF-Editor Tutorial

4 General concepts and terms Model-Driven Software-Development key concepts Provide optimal level of abstraction for each role in the (development) process Separation of concerns (e.g. separate app-logic from ui) Avoid storing redundant information (use single source of information) Interprete the information during runtime Use Code-generators to create code-artifacts in concrete languages (e.g. Java) => Provide custom languages and tools

5 Meta-Meta-Model (Bsp: Ecore) Meta-Grammar (E)BNF Meta-Model / Data Model / Schema / … Grammar Model (Instance) Valid sentence of grammar Domain specific lanuages (DSL) Textual and graphical presentation Model-Driven Software-Development (MDSD) Concepts of the language independent of presentation (= abstract syntax) General concepts and terms Example Instance of ANTLR Java Programming Language Java-Class (e.g. FireDetector.java) FireDetector1 (object)

6 Documentation Programming Interface (API) PersistencyPresentation UML-Class-Diagrams WIKI HTML/Web (MOT- Concept) Dokumente (Word/Open Office...)... C++ Java (=MOT-API)... XML Binary format Database... Web (Thin-Client) MOT-Editor (Fat- Cl.)... The MOT-Language/MOT-API = A sample Meta-Model Meta-Model (MOT-Language) Model (*.mot) Generate (>90%) Instance of read/write use Model (*.mot) Model (*.mot) manipulate

7 Documentation Programming Interface (API) PersistencyPresentation UML-Class-Diagrams WIKI HTML/Web (MOT- Doku) Dokumente (Word/Open Office...)... C++ Java (=MODTO...)... XML Binary format Database... Web (Thin-Client) aloXerv-Client (Fat~)... The MOTs as central source of information *.mot Managed Objects Generate (>90%) Instance of read/write use Managed Objects manipulate Interprete (via MOT-API)

8 The Ecore modeling language (class hierarchie)

9 A simple data model (Ecore meta-model) Sample-Model/Instance (XML)

10 The development-process with FXL Editor and FXL Generator Edit/extend the meta-model (*.ecore) Use code-generator for *-API/Editor Hand-code additional functionality in *-API; Customize Editor Build/release the editor

11 The Component Description Framework and the CDF Editor

12 The Component Description Framework and the CDF-Editor Framework for Application and Tool development based on MDSD Component = Module = Project = Artifact For each Component you can define as many Meta-Models as you want Basis = Based on FXL: Ecore-(meta-)modeling, code-generation, mighty Editor- Framework Integration of an Ecore-editor and the code-generators into one tool Run API/editors as Eclipse-Editors and in the CDF Standalone-Editor

13 The Component Description Framework and the CDF-Editor (2) Existing open source CDF-extensions: History (Release-Notes)/svn, Files (e.g. for viewing PNB), Reviews, I18n, Decisions, Eclipse-Help, Authentication, Tasks, Actions, (Joke of the day), … AloXerv-specific extensions (closed source) Domain-Configuration, Data-Channels, Security-Config, SDC-Sample, Cu- Handler-Config,... CDF-Standalone Can be used by none-developers (in contrast to Eclipse IDE) No usage of Eclipse-File-System no need to perform refresh workspace after svn-update Very flexible/customizeable (which extensions to show) – Use as demo-system to manage aloXerv-site-installation – Use as application to manage aloXerv help – … Can be used to get overview ==> tables

14 The CDF-Editor (details/architecture)

15 How to create an extension of the CDF-Editor without writing one line of Java-code CDF Development Tutorial Ulrich Dinger

16 Ecore meta-model Sample-Model/Instance (XML)

17 Optional: Extend meta-model to allow users to vote for cites with POOR … GOOD … EXCELLENT (enumeration) Show cites in a table …

18 Extended Ecore meta-model Extended sample-Model/Instance (XML)

19 Extended Ecore meta-model
