A Diameter AVP
See RFC3588 section 4 for details.
An AVP consists of a code, some flags, an optional vendor ID, and a payload.
The payload is not checked for correct size and content until you try to
construct one of its subclasses from it. Eg
avp = ...
try:
application_id = AVP_Unsigned32.narrow(avp).queryValue()
...
except InvalidAVPLengthError, ex:
..
Members:
code (int) The AVP code
vendor_id (int) The vendor ID. Assigning directly to this has the delayed effect of of setting/unsetting the vendor flag bit
payload
