Method Detail

initialize

public void initialize(Set<Class<?>> classes,
                       VaadinContext context)

Description copied from interface: VaadinContextStartupInitializer

Applies this initializer to the given context

Specified by:

initialize in interface VaadinContextStartupInitializer

Parameters:

classes - the Set of application classes which this initializer needs to do its job

context - the VaadinContext to use with this initializer

init

@Deprecated
public static void init(Set<Class<?>> classes,
                                    javax.servlet.ServletContext context)

Deprecated. Use init(Set, VaadinContext) instead by wrapping ServletContext with VaadinServletContext.

Initializes the AppShellRegistry for the application.

Parameters:

classes - a set of classes that matches the HandlesTypes set in this class.

context - the servlet context.

init

public static void init(Set<Class<?>> classes,
                        VaadinContext context)

Initializes the AppShellRegistry for the application.

Parameters:

classes - a set of classes that matches the HandlesTypes set in this class.

context - the VaadinContext.

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, VaadinContext)

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, VaadinContext)

contextInitialized

public void contextInitialized(javax.servlet.ServletContextEvent sce)

Specified by:

contextInitialized in interface javax.servlet.ServletContextListener

contextDestroyed

public void contextDestroyed(javax.servlet.ServletContextEvent sce)

Specified by:

contextDestroyed in interface javax.servlet.ServletContextListener
