-module ActionController #:nodoc:
-  module Caching
-    # Sweepers are the terminators of the caching world and responsible for expiring caches when model objects change.
-    # They do this by being half-observers, half-filters and implementing callbacks for both roles. A Sweeper example:
-    #
-    #   class ListSweeper < ActionController::Caching::Sweeper
-    #     observe List, Item
-    #
-    #     def after_save(record)
-    #       list = record.is_a?(List) ? record : record.list
-    #       expire_page(:controller => "lists", :action => %w( show public feed ), :id => list.id)
-    #       expire_action(:controller => "lists", :action => "all")
-    #       list.shares.each { |share| expire_page(:controller => "lists", :action => "show", :id => share.url_key) }
-    #     end
-    #   end
-    #
-    # The sweeper is assigned in the controllers that wish to have its job performed using the <tt>cache_sweeper</tt> class method:
-    #
-    #   class ListsController < ApplicationController
-    #     caches_action :index, :show, :public, :feed
-    #     cache_sweeper :list_sweeper, :only => [ :edit, :destroy, :share ]
-    #   end
-    #
-    # In the example above, four actions are cached and three actions are responsible for expiring those caches.
-    #
-    # You can also name an explicit class in the declaration of a sweeper, which is needed if the sweeper is in a module:
-    #
-    #   class ListsController < ApplicationController
-    #     caches_action :index, :show, :public, :feed
-    #     cache_sweeper OpenBar::Sweeper, :only => [ :edit, :destroy, :share ]
-    #   end
