Constructor Details

#initialize(main_widget, plan, logfile, starting_cycle) ⇒ Stepping

Create a step-by-step replay starting at the beginning of a cycle in the log stream

Parameters:

  • main_widget —

    this widget’s parent

  • plan (DRoby::RebuiltPlan) —

    the plan into which the replay is done. Most of the time it will be the plan that is being displayed

  • logfile (DRoby::Logfile::Reader) —

    the log file

  • starting_cycle (Integer) —

    the ID of the cycle at which to start stepping
