What You Already Have  A detailed project description.

 Source codes of a half implemented Eclipse plug-in.

 An extended DJ package.

– Parse the Selector Language – Generate a list of StrategyExpressions and a list of NodeSubsetExpressions.

 Lab exercises

What You Need to Do  Write your own class dictionary of the Selector Language.

 Add a syntax sensitive Selector Language Editor to this plug-in.

 Add traversal highlighting functionality to the Class Diagram Editor.

Eclipse Platform Overview  The definition from the official website: – Eclipse is a kind of universal tool platform an open extensible IDE for anything and nothing in particular.  The Java compiler itself is a plug-in!!!

Eclipse Platform Overview

Eclipse Platform Overview Eclipse core Plugin.xml

Plug-in Manifest file Plugin_name.jar

Plug-in …

What ’ s Inside plug-in.xml

 Function is added to the system using a common extension model.

 Extension points – well-defined function points in the system that can be extended by plug-ins  When a plug-in contributes an implementation for an extension point, we say that it adds an extension to the platform.

Example

Selector Language Editor  A simple extension to

org.eclipse.ui.texteditor

 Add syntax rules.

– Syntax coloring is provided in the platform text framework using a model of damage, repair, and reconciling  Do Lab exercise 18.

GEF MVC Architecture  MVC: Model-View-Controller.



Model:

represents the data being displayed 

View:

responsible for rendering the data 

Controller:

responsible for handling user input, making changes on the model if necessary, and refreshing the view.

GEF MVC Architecture

MVC Example 5

Class Diagram Editor  Model ---- model – BasicSubpart, ClassDiagramModel, Connector BasicSubpart ClassDiagramModel Connector

Class Diagram Editor  View ---- figure – ClassFigure, PolylineConnection  Anchor.

 Can be black boxes for this project.

Class Diagram Editor  Controller ---- EditPart – ClassEditPart, ConnectorEditPart  Installed EditPolicies.

e EditPart

ClassDiagramModel  A list of all the ClassDiagramModels in the diagram will be given to you.

 getSourceConnections() method.

 getTargetConnections() method.

 isSelected() method.

 setSelected(

boolean

b) method.

 How to have the list of all the connectors?

Construct DJ Class Graph  Create a new class graph.

   – Be sure to use: edu.neu.ccs.demeter.aplib.cd.ClassGraph

addConstructionEdge ( String String source, target) String addAlternationEdge ( name, String String source, target) addInheritanceEdge ( String String target) source,

Construct DJ Traversal  Class Graph + Strategy = Traversal.

   Be sure to use: edu.neu.ccs.demeter.aplib.Traversal

getEdgeSets () getNodeSets ()

Show The Path  What you get from getEdgeSets () getNodeSets () are lists of names.

and  Rescan the ClassDiagramModel list, when a selected ClassDiagramModel is met, setSelect().

 If it’s not NodeSubsetLanguage, also scan the Connector list, do the same thing.

The Hooks     public static ClassGraph createClassGraph(List nodeList) public static String highlightTraversal (ClassGraph cg, List nodeList, String strategy, boolean is_nodeset) public static String RefreshStrategy(String name) public static boolean isNodeSet(String name)

Good Luck!

The End
