    dude whats that got to do with th Observer Design Pattern?

    are you lost?

  • Observer/Subject. I find it useful to think of patterns in terms of business relationships.

    How does this relationship work?

    Suppose you, me, our neighbors are subscribed to Time Warner, we are observers; Time Warner would be the subject. Time Warner keeps a list of subscribed observers and constantly sends us subject material.

    You could expand the pattern; implement behavioral states (more channels), overload your observers with extra features (dvr equipment) etc...

  • Thank you for making this chewable.

  • good stuff. short and simple.
