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)
