Generally not -- you define the "event" as a serializable data structure that *describes* the transformation to execute, and that gets stored in the event stream. When you reload the Actor, you "replay" those events, and your recovery logic interprets the events to actually change the data. You generally have a function that takes the stream of events and the starting state, and does this interpretation.
In principle, I suppose you *could* save the functions themselves as bytecode, but I don't think I've ever heard of anyone doing so, and it seems quite dangerous -- it could fail to load because dependencies had changed, and other such problems. (And it would likely be very bulky and redundant.)
