Class DevBundleBuildingHandler

java.lang.Object

com.vaadin.base.devserver.DevBundleBuildingHandler

All Implemented Interfaces:

DevModeHandler, RequestHandler, Serializable

public final class DevBundleBuildingHandler
extends Object
implements DevModeHandler

A fake DevModeHandler whose only purpose is to eagerly show a "build in progress" HTML page to the user, during the creation of the development bundle.

The getPort() method returns a fixed value of -1, meaning that this handler will not start a server listening for incoming requests.

Most of the other methods should not be invoked, and they may throw an exception if called.
