Class ControllerContextHelper

java.lang.Object
  org.apache.cocoon.servlet.controller.ControllerContextHelper

public final class ControllerContextHelper
extends Object

This class helps with storing and retrieving the controller context. Internally it uses the current servlet request. Thanks to the servlet-service framework, the current request becomes the parent of all sub-requests that use e.g. the 'servlet:' protocol. This means that it is enough to store objects that should be available in a sub-request into the current request.
