org.apache.cocoon.environment.wrapper
Class MutableEnvironmentFacade

java.lang.Object
  org.apache.cocoon.environment.wrapper.MutableEnvironmentFacade

All Implemented Interfaces:

org.apache.cocoon.environment.Environment

public class MutableEnvironmentFacade

extends Object

implements org.apache.cocoon.environment.Environment

Enviroment facade, whose delegate object can be changed. This class is required to handle internal redirects in sitemap sources ("cocoon:"). This is because org.apache.cocoon.components.source.impl.SitemapSource keeps the environment in which the internal request should be processed. But internal redirects create a new processing environment and there's no way to change the one held by the SitemapSource. So the processing of internal redirects actually changes the delegate of this class, transparently for the SitemapSource.
