[pox-dev] Using connection object at my component in POX

[chenli]

Hello,

I want to get connection object to send the ofp_flow_mod object.

I already see the Communicating with a Datapath(Switch) section which in
POX Wiki.

And I also create a class to get the connection object which saved in
connections attribute.

But I'd want to know how to use the instance for My_class which created at
the component?

I tried it at the component I wrote like below.

from pox.core import core
import pox.openflow.libopenflow_01 as of
from pox.lib.recoco import Timer
import time

#----------------------------------------------------
class c_class (object):
  def __init__(self):
    self.connections = set()# Attribute
    core.openflow.addListeners(self) #Add Listener
  def _handle_ConnectionUp (self, event):
    self.connections.add(event.connection)
#----------------------------------------------------

def launch():

  c_object = c_class() #Get instance

  msg = of.ofp_flow_mod()
  msg.match.dl_type = 0x0800
  msg.match.nw_src = "192.168.1.6"
  msg.actions.append(of.ofp_action_output(port = 24))

  c_objcet.connections.send(msg)


But I got the error message "NameError: global name 'c_objcet' is not
defined".

Can someone help me or give me an example?

Thanks.
