public abstract class Controller
extends Object

Controller is part of the HMVC pattern.

 Example:

 public class MyController extends Controller {
  private MyModel myModel;
  private MyView myView;
   
        public void handleEvent(MyEvent evt) {
                switch (evt.getType()) {
                case EDIT:
                        executeController(new MyController());
                        break;
                                                
                case EXPORT:
                        executeTask(new ExportTask());
                        break;                  
                }
        }

        public void execute() {
     myModel = new MyModel();
     myView = new MyView();
     setModel(myModel);
     setView(myView);
     showView();
  }
 }
