Analysis

Overview

The concept of different types of frames is changed. Now we don't have text frame, movie frame, audio frame and so on. We just have a frame with a content. This frame content can be text, movie, audio and so on which means that the frame content contains a resource and tells how this resource is going to be visualized. Frame has one-to-one association with its content. But the frame content has many-to-many association with a resource in the book.

• Frame Content Concept
  • Each frame has style and content.
  • Each frame has at most one content at a time.
  • The content of a frame is replaceable. For example if a frame has movie content then the same frame can change its content with image content.
  • Different kinds of content:
    • Text content
    • Audio content
    • Movie content
    • Image content
    • Browser content
    • Flash content
    • Pdf content
    • Comment content
  • Frame content can be non-defined or unsupported. The content is unsupported if it is created with non-present plug-in for example.

Task requirements

• Create the basic hierarchy of the frame content.
• The basic hierarchy should be in org.sophie2.base.model.book
• Functionality and properties of frame content that the hierarchy should provide:
  • Frame content could be non-defined and unsupported.
    • (Optional)Unsupported
      • (Optional)If the frame content is created with non-present plug-in for example then it is unsupported.
  • Provide that Frame content should be:
    • replaceable
      • The user should be able to insert a frame without content and add it afterward or can change the content when he decides.
    • various kinds(text, audio, video, image, other)
      
• Make basic implementation of the frame content hierarchy (unit tests included).

Task Result

• The result should be source code.

Implementation idea

• Basic hierarchy could be implemented with composition of the frame content in the frame.
• Write source code.

How to demo

• Show source code and run application.
• Show unit tests and run them.
• Answer if there are any questions.

Design

• Basic hierarchy
  • Base Frame content class
    • (Optional if there is time)Derived classes for all the concrete contents. In this iteration at least for TextFrameContent and HtmlFrameContent.
    • Frame Content could have no more than one main resource and many secondary resources.
  • Class Frame composed with Frame Content.
    • The content should be value property of the Frame with default value - null. This is supposed to be non-defined frame content at least for now.

Implementation

• It is barely impossible to link the changes but the classes that should be reviewed are:
  • org.sophie2.base.model.book.FrameContent
  • org.sophie2.base.model.book.Frame
  • org.sophie2.base.model.book.FrameContentDemo
  • org.sophie2.base.model.book.FrameContentUnitTest
