• Assignment 5 turnin requirements
• Editor changes that may affect you
  • UserInterface requires getKeyDescriptor.
    You can get this String from the KeyCommands
  • KeyCommands is now a class rather than an interface
  • KeyCommandsNormal extends KeyCommands
  • KeyCommands no longer has a setSesion() method
  • The getCommand method of KeyCommand returns an ArgumentCommand rather than an ExecutableCommand. This allows you to use the same KeyCommand for all sessions of a user interface.
  • KeyCommands has a method setCodesFromFileFile that reads from a configuration file.
• Problem: how do you make a configuration file for Key Commands?
  • The program nees to convert from a key description (String) to a key code (int)
  • A simple key description in the name of the key given in the KeyEvent class
  • How does a program convert the name of a field to the value of that field?
