Class PublishedFileHandler

java.lang.Object
  com.vaadin.server.communication.PublishedFileHandler

All Implemented Interfaces:

RequestHandler, java.io.Serializable

public class PublishedFileHandler
extends java.lang.Object
implements RequestHandler

Serves a connector resource from the classpath if the resource has previously been registered by calling LegacyCommunicationManager.registerDependency(String, Class). Sending arbitrary files from the classpath is prevented by only accepting resource names that have explicitly been registered. Resources can currently only be registered by including a JavaScript or StyleSheet annotation on a Connector class.
