      the result of checking

      Set the accessible flag for this reflected object to true if possible.
      Parameters:
      ao - the accessible object
      Returns:
      true if the accessible flag is set to true; false if access cannot be enabled.
      Throws:
      java.lang.SecurityException - if the request is denied by the security manager
