-// Event hierarchy implementation classes ======================
-
-// The implementation of a valuetype in C++ needs to derive from
-// the IDL generated OBV_Event, which provides the data members
-// and their accessor/modifier.
-// In TAO it is possible to have inline instead the standard virtual
-// accessor/modifier functions. But then they can't be overridden for
-// marshalling. (doesn't yet work anyway but will come soon %!).
-//
-// The 'client' of a valuetype (client means here the parts
-// of an application which locally access the valuetype through its interface)
-// uses pointer to the 'Event' class, or better the Event_var type
-// which is similar an object reference _var.
-//
-// Specs say that the instances of Event_impl should be created by means
-// of Event_init::create (), which are equivalents to the init () operations
-// in the IDL of the valuetype --- its not yet impl. and will come later on %!
-// Today you have to declare your own create () member.
-//
-// One more step to make (far way from Event to Event_impl, isn't it?):
-// We must mix in a class to have a reference counter implementation
-// (: Sit down and type twenty times CORBA::DefaultValueRefCountBase :)
-// A plus is its on your hand to choose possibly a reference counter
-// with (like the standard supplied one) or without lock. But I hate
-// the fact that reference counting is based on virtual _add_ref ()/
-// _remove_ref () functions, which may cause substantial overhead.
-// I'm thinking of a TAO option to let tao_idl mix in the reference counter
-// previous and generate _var classes which access inline functions.
-// ... And I wonder how the OMG want to manage cyclic graphs with
-// reference counting.

-  // All operations in valuetypes are virtual.
-
-  // The state member for the event time is yet implemented in OBV_Event
-  // (or in the Event class, if -Wb,obv_opt_accessor is given to tao_idl).
-};
-
-// An instance of the Event_factory class has to be registered
-// in the ORB with ORB::register_value_factory ().
-
-// Then the unmarshal engine can obtain a fresh instance of Event_impl
-// from the (user implemented) Event_factory::create_for_unmarshal ()
-// function. These should return a pointer to Event, but as long as
-// covariant return types are not commonly supported one has to
-// return a pointer to CORBA::ValueBase. This option handles the macro
-// in front of the create_for_unmarshal () declaration. Now the code
-// is compiler portable, but not ORB vendor portable ...
-
-// ... but stop a moment. We don't want an instance of Event.
-// It is only the base class for Temperature, Position and Log_Msg.
-// We didn't declared Event as abstract valuetype, cause we want to
-// store the timestamp in it. So we express that no instance can
-// exists while we don't make a factory for it (and don't register one).

-// The procedure to register your instance is currently not much like
-// OBV specs says. This implementation has currently one
-// process-wide map for the registered factories. The specs want one

-// more practicable to have simply just one map. (%!)
-// Further on it is non-standard how the repository id of the valuetype
