Hack around PySNMP lack of generic types
 
This was written against PySNMP 3.3.x, apparently 3.4.x has
some fixes to make this all cleaner, but I haven't had time
to revisit the question just yet.

Modules
		pysnmp.proto.rfc1902 pysnmp.proto.v1 pysnmp.proto.v2c

Classes
		SimpleConverter   class SimpleConverter     Simple callable object that just does target(value.get())     Methods defined here: __call__(self, value) __init__(self, target)

Functions
		ipConvert(value) Mapping that returns v2c.IpAddress(value.get()) nullMapping(value) Mapping that just returns value unchanged typeCoerce(value, implementation) Coerce value to implementation-friendly version   value -- Python or PySNMP value to be represented as a value         compatible with the implementation given implementation -- v1 or v2c modules from PySNMP, they are         simply used to choose between use of data-type mappings
