public void process(Set<Class<?>> classes, ServletContext context) throws ServletExceptionDescription copied from interface:
ClassLoaderAwareServletContainerInitializerImplement this method instead of
ClassLoaderAwareServletContainerInitializer.onStartup(Set, ServletContext)to handle classes accessible by different classloaders.Specified by:
processin interfaceClassLoaderAwareServletContainerInitializerParameters:
classes- the Set of application classes that extend, implement, or have been annotated with the class types specified by theHandlesTypesannotation, or null if there are no matches, or this ServletContainerInitializer has not been annotated with HandlesTypescontext- the ServletContext of the web application that is being started and in which the classes contained in c were foundThrows:
ServletException- if an error has occurredSee Also:
ClassLoaderAwareServletContainerInitializer.onStartup(Set, ServletContext)

init
public static void init(Set<Class<?>> classes, ServletContext context, DeploymentConfiguration config)Initializes the
AppShellRegistryfor the application.Parameters:
classes- a set of classes that matches theHandlesTypesset in this class.context- the servlet context.config- the vaadin configuration for the application.

getValidAnnotations
public static List<Class<? extends Annotation>> getValidAnnotations()Return the list of annotations handled by this class. This method is thought to be called from external plugins (e.g. Vaadin Spring) that would need to override the
@HandlesTypes-based classpath scanning.Returns:
list of annotations handled by
init(Set, ServletContext, DeploymentConfiguration)
-
getValidSupers
public static List<Class<?>> getValidSupers()Return the list of super classes handled by this class. This method is thought to be called from external plugins (e.g. Vaadin Spring) that would need to override the
@HandlesTypes-based classpath scanning.Returns:
list of super classes handled by
init(Set, ServletContext, DeploymentConfiguration)
