不推荐使用GWT:PlaceHistoryHandler.register？

Question

我有一个GWT应用程序,我移植到GWT 2.4.现在我在这一行上弃用了警告:

 historyHandler.register(placeController, eventBus, defaultPlace);

"不推荐使用PlaceHistoryHandler类型的方法寄存器(PlaceController,EventBus,Place)"

有更好的方法可以在这里获得相同的结果,还是可以安全地忽略警告？

public void onModuleLoad() 
     {
          // Create ClientFactory using deferred binding so we can replace with
          // different impls in gwt.xml
          ClientFactory clientFactory = GWT.create(ClientFactory.class);
          EventBus eventBus = clientFactory.getEventBus();
          PlaceController placeController = clientFactory.getPlaceController();

          // Start ActivityManager for the main widget with our ActivityMapper
          ActivityMapper activityMapper = new AppActivityMapper(clientFactory);
          ActivityManager activityManager = new ActivityManager(activityMapper, eventBus);
          activityManager.setDisplay(appWidget);

          // Start PlaceHistoryHandler with our PlaceHistoryMapper
          AppPlaceHistoryMapper historyMapper = GWT.create(AppPlaceHistoryMapper.class);
          PlaceHistoryHandler historyHandler = new PlaceHistoryHandler(historyMapper);
          historyHandler.register(placeController, eventBus, defaultPlace);
          RootPanel.get().add(appWidget);

          // Goes to place represented on URL or default place
          historyHandler.handleCurrentHistory();
     }
    }

不推荐使用该方法,因为EventBus类型已从中com.google.gwt.event.shared移至com.google.web.bindery.event.shared.正如JavaDocs中PlaceHistoryHandler所指出的那样(没有特别明确),切换EventBus到com.google.web.bindery.event.shared.EventBus类型将解决已弃用的警告.也就是说,目前两种EventBus类型在功能上都是相同的,并且可以安全地忽略警告.
