Analysis

Overview

Manipulating with books is the main goal of sophie2. A book should hold pages, pages can be added or removed from a book. A book should be viewable, savable, exportable.

Task requirements

• Define the connections between books and other related objects (pages, some book repository)
• Define actions related to books
  • for the book itself
    • create
    • destroy
    • copy
    • save/load
    • export
    • import
  • for the objects inside
    • add pages
    • remove pages
    • (re)order pages
    • group pages in chapters
    • set a page to be the cover of the book
  • other actions
    • merge two/many books in one
    • split a book in two/many
• Decide which connections and actions are basic and obligatory and which are optional. Define a class hierarchy that supports the basic connections and actions. In this task a class hierarchy for books should be created. It should contain all interfaces, classes, fields common for all possible kinds of books (if any more than one)

Task result

• The result should include
  • class diagrams
  • source code

Implementation idea

• first identify the classes and the relations between them
• implement the hierarchy
• implement the functionality

How to demo

• show the class diagram and explain the role of the components and how they are related
• show where the implemented packages and classes are

Design

The Book object model consists of three parts:

• Model - in package org.sophie2.base.model.book
• View - in package org.sophie2.main.view.book
• Logic - in package org.sophie2.main.view.logic

The basic actions for books are found in the following classes:
Book.java
BookView.java
BookLogic.java

• These classes provide functionality for:
  • Creating and deleting books.
  • Adding/removing/reordering the pages of a book.
• Some things will not be implemented in this task:
  • copying books requires the CORE_ADDITIONS_R0.
  • saving/loading books will be implemented in the BASE_PERSISTENCE_COMMONS_R0 task.
  • importing/exporting will be implemented at Iteration05 - then there are tasks for that.
  • grouping in chapters is scheduled for Iteration06.
  • other things might be implemented in the next revisions of this task.

Here's the class diagram for these classes:
