If you just use a Swarm List (or a java list, for that matter) and 
addLast the new things, then they will be processed in order.

Yes, that's a common thing.  I believe every single Swarm model does 
that.  Don't you find an example like you need in jheatbugs, or 
jmousetrap?  I wrote a Java version of ElFarol a while ago, you could 
look at that.  OR the Java version of the Artificial Stock Market you 
can grab off http://artstkmkt.sourceforge.net.

If you look in the working examples:
http://www.ku.edu/~pauljohn/SwarmFaq/WorkingExampleCode/java/

I suggest you look at the one Marcus Daniels did FActionArguments.txt

The transition from ObjC to Java was somewhat dicey and Marcus Daniels 
worked out some new, more efficient ways to do the "createActionForEach" 
and he discussed that new "createFActionForEach" thing in some things 
I've saved in the memos directory

http://www.ku.edu/~pauljohn/SwarmFaq/Memos/

All I know is what Marcus taught us on that one. Consult:
