[Swarm-Modelling] Follow up question

[Vijay]

Thanks for the quick reply alex. 

I searched the mailing list archives like you mentioned and found this 
\"reasonably\" clear posting by Paul Johnson on this issue.

http://www.swarm.org/pipermail/support/2000-August/008981.html

This is a relevant passage from the above link:
{
     Each agent first of all has to have a 
    \"handle\" on an action group that exists on the schedule at time 2. If
     there is no action group there yet, then one has to be created and
     returned.  That\'s what this method in the Schedule class does:

     - (id <ActionGroup>)insertGroup: (timeval_t)tVal 

      If the agent catches the return from that, ie with   
 
       mySubSchedule=[theSchedule insertGroup: 2];
}

However, in the above post, PJ never mentions how one can check whether or not 
a subschedule has already been created for a given 
time. Further, if it has been created, then is  there a method in the schedule 
class that returns the corresponding subschedule object for a given time?

Thanks again,
Vijay
