Hi Everyone,


When I try to use the class listed below, I get the statement that self
is not defined.
		
test=TriggerMessage(data)
var = test.decode(self.qname)

I would have thought that self would have carried forward when I grabbed
an instance of TriggerMessage.

Any ideas on this?



The class in question is:


class TriggerMessage(object):
	
	def __init__(self,data):
		"""
		Unpacks the passed binary data based on the MQTCM2 format dictated in
		the MQ Application Programming Reference
		"""

		self.data=data
		self.structid=None
		self.version=None
                self.qname=None
		self.procname=None
		self.trigdata=None
		self.appltype=None
		self.applid=None
		self.envdata=None
		self.userdata=None
		self.qmgr=None


	def decode(self):
		import struct
		format='4s 4s 48s 48s 64s 4s 256s 128s 128s 48s'
		size=struct.calcsize(format)
	        self.data=data	
		self.structid, self.version, self.qname, self.processname,       \
				self.triggerdata, self.appltype, self.applid,    \
				self.envdata, self.userdata, self.qmgr           \
				= struct.unpack(format,self.data)
