Graphical Editing Framework  Enables user to make rich graphical editors  Uses Draw2D to handle visual graphics  Based on MVC Approach

Graphical Editing Framework (contd.)  Controller bridges the Model and the View  Model and View have no knowledge of each other  Each model has an associated edit part i.e. controller and a view

Functioning of Edit Part

Functioning of Edit Part (contd.)  An edit part can play certain roles like Node Role, Container Role, etc.  Node Role – to connect to other nodes  Container Role – to contain child objects  Roles are delegated to Edit Policies which handle Requests  ContainerEditPolicy is installed for container role which handles requests such as AddChild  NodeEditPolicy is installed for node role and handles requests such as target or source connect.

Functioning of Edit Part (contd.)  ContainerEditPolicy then creates a COMMAND called getCreateCommand which is executed and a new object is created and added to the Container  Similarly, NodeEditPolicy creates getConnectionCreateCommand and getConnectionCompleteCommand to start and end the connection  Another policy - XYLayout Policy is used by the container edit part to place children in XY Layout  The behavior of getCreateCommand is shown in a Sequence Diagram

Architecture Design  Package View Controller View Model Editor

Editor Package  ActivityDiagramEditor – creates and loads the graphical editor and the palette  ActivityDiagramPlugin – enables the editor to be installed as a plugin in Eclipse Environment  PaletteViewerCreator – creates palette entries and associates models with each entry  PaletteFlyoutPreferences – sets the palette flyout preferences  GraphicalViewerCreator – this is the actual graphical editor i.e. the drawing pane  OverviewOutlinePage – this class gives the outline view of the diagram

Inspection Checklist  The symbols used in the class diagrams conform to UML standards  The classes in the class diagrams have a corresponding description provided in the Architecture Design document  The description of the classes in the Architecture Design document are clear and adequate  The symbols used in the sequence diagrams conform to UML standards  The sequence diagrams are clear and understandable  The attributes in the USE model are compatible with the attributes of the corresponding class diagrams  The multiplicities in the USE model are reflected in the Class diagram  Classes in the Architecture Design (Activity Diagram) correspond to classes in the USE model  All model elements and relationships as outlined in the Vision Document (Section ) are present in the Architecture Design document as classes

Project Plan Already developed – 5.5 KSLOC which is 50% of the entire project  5500 SLOC / 150 hours = SLOC/hour (productivity)  5500 SLOC /.50 = SLOC (total SLOC)  Remaining SLOC = 5500  (5500 SLOC)/ SLOC/hour = 150 hours (Remaining Time)

Project Plan (contd.)  150 hrs/6 hrs per day = 25 days  Approximately 25 days for coding, testing, etc.  And 10 days documentation which includes component design, user manual, etc.  Total of 35 days  Approximate Completion Date – April 20 th 2005

Test Plan  Features to be tested – all features from Vision Document Version 1.0 Drawing Sequence Diagrams Drawing Activity Diagrams Importing Models Exporting Models Printing Diagrams  JUnit Plugin for Eclipse will be used for Unit testing  Only functional testing will be performed  All Test Results will be documented
