COMP 405 Spring 2015	HW02:  Extending the State Pattern Demo

As with all assignments, the first part of the assignment is to peer review 3 groups' work from the previous assignment.   The peer review assignments are posted on the HW01 wiki page on the SharePoint site.

The HW02 groups are the same as the HWO1 groups.

The goals of this assignment are to take your HW01 demo and do the following:

• Extend your code to be able to dynamically, i.e. at run-time, modify the states involved and the transition graph
  • The changes to the transition graph must include at least some changes to the transitions between existing states.   That is, the new transitions cannot only involve the new states.
• Modify your system to use lazy evaluation.   Possibilities include the lazy evaluation of
  • The states
  • The transitions
  • Other properties and/or behaviors
• Ideally, the above modifications would involve minimal changes to your codebase.   Mostly likely, that was not the case to some degree.   It's possible that you may have to re-architect some significant portion of your system and/or rethink what your system does and how it does it.   In your discussions, explain
  • Why you believe that such changes were required. 
    • Look for mistakes that were made.
    • Look for misconceptions that affected how you thought about the problem.
      • For instance, look at one's initial conceptualization of the scope of the application -- for instance, were you thinking about the system in a too narrow context? 
      • Perhaps you didn't properly understand the design patterns involved and how thinks should/could be decoupled in the system.
      • Etc., etc.
      • In all cases, exactly what are the differences in how you did think about the system and how you should have been thinking about the system?   Be specific and complete!
    • Simply saying something to the effect of "we didn't know how to do it from what we had" is not an acceptible reason.    Look for solid engineering and/or theoretical factors that drove the situation.  
  •   What changes you made to the system and why you made them.
    • What was acheived by making the changes?    What features and capabilities were added?
    • What did you give up by making the changes you made?  
  • Include the pieces of the this discussion that do not fit in other parts of the general discussion template in the "Additional Notes" section or make a new section for it if you prefer.

Please include a wiki link directly to your HW01 wiki page.   The link should look something like  [[HW01 NetID1, NetID2]] (Just type the [[ and then scroll down the list of possible link targets until you find your HW01 page.)
