-- Exceptions Members --
------------------------
-- A PolyORB error is notionally equivalent to a CORBA exception.
-- It is composed of:
-- - Exception Id,
-- - Exception Member.
type Exception_Members is abstract tagged null record;
-- Base type for all PolyORB exception members. A member is a
-- record attached to an exception that allows the programmer to
-- pass arguments when an exception is raised.
type Exception_Members_Access is access all Exception_Members'Class;
procedure Free is new Ada.Unchecked_Deallocation

-- systeme exception has been raised.

type InvalidPolicy_Members is new Exception_Members with record
