[Swarm-Support] Swarm serialization

[Marshall, James A R]

Hi,
  I've been looking through the FAQ, user-manual, etc. and haven't found
much explanation of how to do serialization in Swarm. If anyone can point me
to any docs or sample code for doing this, particularly in Java, then that
would be appreciated.
  Alternatively, if anyone can let me know the extent of serialization
support for Java in Swarm at the moment then please do (for example I turned
up an email from Marcus in the archives about Java object serialization,
which said basic Java objects could be serialized, but Java collections
couldn't. That was 2000, has anything changed?)
  Thanks in advance,
        James

If I understand what you're asking, check out:

http://www.swarm.org/swarmdocs/set/swarm.activity.actioncreatingto.protocol.
html

The syntax should be something like:

[modelActions createActionTo: preyspace message: M(rearrange:) : preyProb];

Don't forget the ":" inside the "M" macro...
