RE: FCallImpl

[Fred Wan]

So, are you suggesting not to use FActionCreatingForEachHomogeneous
interface at all?

I am trying to understand how this works, but it is obviously very
complicated. There is also an assignment to 'actionForEach' in the heatbug
example of which understand the purpose because it is never used anywhere
else.

    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);
    }

I tried to apply it to the SimpleObserverBug tutorial example but I just get
a crash and no further message. This is probably _the_ drawback of dynamic
binding. The only difference is, is that heatbugList is a java List, while
bugList is a swarm List, but according to the manual (interface
FActionCreatingForEachHomogeneous) this should not be a problem.

        SimpleBug proto = (SimpleBug) bugList.getFirst();
        sel = new Selector(proto.getClass(), "randomWalk", false);
        actionForEach=
            modelActions.createFActionForEachHomogeneous$call
                (bugList,
                 new FCallImpl(this, proto, sel,
                   new FArgumentsImpl(this,sel,true)));
        } catch (Exception e)
        {
        System.err.println("Exception randomWalk: " +
        e.getMessage ());

Thanks.
