You've probably already found it by now, but for the benefit of archive
readers: setUnjellyableForClass() is actually defined in the
twisted.spread.jelly module. Several PB things are defined in one of
(banana.py, jelly.py, flavors.py, spread.py) and then imported into the
others. I usually end up doing the "big grep" to find the actual definition:
find ~/stuff/Twisted -type f |xargs grep setUnjellyableForClass |grep def
Some of it is for historical reasons, some of it has to do with the most
appropriate place for the implementation not always being the most
convenient place for use.
In general, banana.py is the lowest level token-to-bytestream layer,
jelly.py is the object serialization that sits above it. spread.py is where
the Broker class is implemented (as well as utility functions like
pb.Connect and pb.getObjectAt), and flavors.py covers the Referenceable /
Copyable / Cacheable subclasses.
