de.hpi.eworld.core.ModelManager
The ModelManager is the central data management class in eWorld. It manages all ModelElements. If any of the plugins wants to add or remove a ModelElement, it has to do so by calling this ModelManager. Singleton class: There is only one ModelManager

      endEdit.setText(Integer.toString(oldEndTime)); //reset to the previous
      // value since the new is invalid
      return;
    }
      
    ModelManager mm = ModelManager.getInstance();
    int startTime = mm.getSimulationStartTime();
  // //check if the new value is valid (must be greater than the starttime!)
    if(time <= startTime)
      endEdit.setText(Integer.toString(oldEndTime)); //reset to the previous
    //value since the new is invalid
    else {
  // //save new end value
      oldEndTime = time;
  // /* notify modelmanager
  // * DO NOT NOTIFY THE MODELMANAGER BEFORE SAVING THE NEW TIME
  // * INTERNALLY IN oldEndTime. Otherwise this will result in
  // * an endless notification loop (timeline notifying the modelmanager
  // * which in turn notifies all listeners such as the timeline and so on).
  // * the timeline checks if the time change propagated by the modelmanager
  // * actually is a time change at loadTimes().

      mm.setSimulationEndTime(time);
      timeline.updateSimulationTime();
