Summary

This was a short but juicy chapter. Take a look at what we have learned:

• We learned how to get path info, parameters, and fragments in the URL by using the VaadinRequest.getPathInfo, VaadinRequest.getParamenter, and Page.getUriFragment methods.

• We learned how to get a referent to the current VaadinRequest by calling VaadinService.getCurrentRequest().

• We learned how navigators make it easy to implement navigation capabilities through fragments by adding instances of View to a Navigator.

• We learned how easy it is to preserve state in Vaadin applications by using the @PreserveOnRefresh annotation in our UI implementations.

• We learned how to identify users and store related data by using VaadinSession.

• We learned how to use menus and key shortcuts.

Congratulations. Knowledge acquired. You are ready for the next chapter where we will be covering a really interesting topic: Tables and trees. See ya!
