    • AbstractCommand

      protected AbstractCommand​(String requestContext, String urlPattern, String contentTemplate, Object target)
      Constructs a new Command with a specified wiki context, URL pattern, content template and target. The URL pattern is used to derive the JSP; if it is a "local" JSP (that is, it does not contain the http:// or https:// prefixes), then the JSP will be a cleansed version of the URL pattern; symbols (such as %u) will removed. If it the supplied URL pattern points to a non-local destination, the JSP will be set to the value supplied, unmodified.
      Parameters:
      requestContext - the request context
      urlPattern - the URL pattern
      contentTemplate - the content template; may be null
      target - the target of the command, such as a WikiPage; may be null
      Throws:
      IllegalArgumentException - if the request content or URL pattern is null

      Description copied from interface: Command
