org.grails.plugin.vaadin
[Groovy] Class GrailsVaadinApplication

java.lang.Object
  com.vaadin.Application
      org.grails.plugin.vaadin.VaadinApplication
          org.grails.plugin.vaadin.GrailsVaadinApplication

abstract class GrailsVaadinApplication
extends VaadinApplication

A Vaadin Application that provides a request-dispatching framework with a Grails-like Model-View-Controller architecture.

Users should override this class, when creating the Application class for their Vaadin project.

It starts listening to changes to the fragment in the browser URL, and dispatches requests to appropriate Vaadin Controllers.

Note that this functionality is optional - a user can disable this by simply overriding the Application class directly.
