  - 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
