Pickle __getstate__ __setstate__ and restoring n/w - beazley pg 172

[Veek. M]

import socket
class Client(object):
 def __init__(self,addr):
  self.server_addr = addr
  self.sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
  self.sock.connect(addr)

 def __getstate__(self):
  return self.server_addr
 
 def __setstate__(self,value):  
  self.server_addr = value
  self.sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
  self.sock.connect(self.server_addr)
-----------------

We'd use it like so:
x = Client(192.168.0.1)
import pickle
pickle.dump(x) #getstate gets called and returns IP for pickling.

#program exits, we restart it
x=Client(None)
x = pickle.load(fh) #Is the IP passed to setstate??????
x.__setstate__(self, unpickledIP) ???
Is this correct?
