FCallImpl

[Fred Wan]

Hi,

In jHeatBugs there is a call to FCallImpl:

    try {
      Heatbug proto = (Heatbug) heatbugList.get (0);
      Selector sel =
        new Selector (proto.getClass (), "heatbugStep", false);
      actionForEach =
        modelActions.createFActionForEachHomogeneous$call
        (heatbugList,
         new FCallImpl (this, proto, sel,
                        new FArgumentsImpl (this, sel, true)));
    } catch (Exception e) {
      e.printStackTrace (System.err);
    }

The creation of the object proto is somewhat puzzling. It seems that a
prototype of the objects in the heatbuglist is created by popping the first
object from the list. Since it is a call to createFActionForEachHomogeneous
this object is identical to the other objects in the list. However, its
function is unclear to me and the reference guide is very brief about it.
Could you please provide some clarification?

Thanks,
