    • generate

      public String generate()
      Generates the RSS resource. You probably want to output this result into a file or something, or serve as output from a servlet.
      Specified by:
      generate in interface RSSGenerator
      Returns:
      A RSS 1.0 feed in the "full" mode.

    • generateFeed

      public String generateFeed​(Context wikiContext, List<Page> changed, String mode, String type) throws IllegalArgumentException
      Generates a feed based on a context and list of changes.
      Specified by:
      generateFeed in interface RSSGenerator
      Parameters:
      wikiContext - The WikiContext
      changed - A list of Entry objects
      mode - The mode (wiki/blog)

    • setEnabled

      public void setEnabled​(boolean enabled)

      Specified by:
      setEnabled in interface RSSGenerator
      Parameters:
      enabled - whether RSS generation is considered enabled.
