syntax etc.

[Holger Perlt]

Hello,

I would like to ask again for the solution of my problem concerning
the Averager. There are two problems:

(I) Using the Averager (getting the numbers  from a List):
***********************************************************

Inside AFonds.m (defining AFonds) I have the build routine:

- buildObjects
{

  AvPreisList = [List create:  [self getZone]];

  AveragePreis = [Averager createBegin: [self getZone]];
  [AveragePreis setCollection: AvPreisList];//here I would assigne the
AvPreisList to the Averager
  AveragePreis = [AveragePreis createEnd];

  return self;

}


The Averager is used inside getWinAvPreis:

- (double) getWinAvPreis
{

  double ap;
  Integer *hh;
  ap = 0.0;


   if(Time < 10){
    hh = [Integer create: [self getZone]];
    [hh setNum: PreisPerAktie];
    [AvPreisList addLast: hh];
    ap = AvPreis;
  }
  else{

    [AvPreisList removeFirst];
    hh = [Integer createBegin: [self getZone]];
    [hh setNum: PreisPerAktie];
    [AvPreisList addLast: hh];

    ap = [AveragePreis getAverage]; //this call is the problem:
AvPreisList has a getNum - method
                                        // to export its numbers; how can I 
tell it this to AveragePreis???
    }


        return ap;
}

(II) Adding to the list:
************************

In the routine getWinAvPreis (above) I have recognized that probably no
element
is added with [AvPreisList addLast: hh]. Using 

ap = (double)([AvPreisList getCount]);

and showing ap via EZGraph  in the ObserverSwarm  I see only zero. I.e.,
no element has been added
to the list?!

Best regards,

Holger
