INTERFACE RemoteView;

IMPORT NetObj, Thread;

 A RemoteView.T is a network-object version of a View.T.  This
   interface is under active development for Juno views, so it is
   subject to change. 


EXCEPTION Error(TEXT);

TYPE
  T = NetObj.T BRANDED "RemoteView" OBJECT
      METHODS
        startrun () RAISES {NetObj.Error, Thread.Alerted};
        endrun   () RAISES {NetObj.Error, Thread.Alerted};
        event (tfactor: REAL; nm, args: TEXT)
               RAISES {Error, NetObj.Error, Thread.Alerted}
      END;

 The startrun and endrun methods must be called at the
   start and end of each run of the animation.


   The event method invokes the output-event named nm with
   arguments args.  The args string should be a symbolic
   expression such that Sx.Read(TextRd.New(args)) will not
   fail.  The tfactor is the amount of time that a one-second
   animation within an event should actually take in terms of
   real seconds (on the wall clock).  The Error exception is
   raised with a descriptive error message if there was an error
   parsing the arguments or invoking the named event on those
   arguments. 


END RemoteView.
