[Pysnmp-dev] Definition of Opaque class

[Fero K. <fer...@gm...>]

Hi,

I am new to PySNMP, I am trying to use it in my application.

I am unsure, whether definition of following class in
pysnmp/proto/rfc1155.py is correct:

class Opaque(univ.OctetString):
    tagSet = univ.Integer.tagSet.tagImplicitly(
        tag.Tag(tag.tagClassApplication, tag.tagFormatSimple, 0x04)
        )

Definition of Opaque in RFC 1155 is:

3.2.3.6.  Opaque   This application-wide type supports the capability
to pass arbitrary
   ASN.1 syntax.  A value is encoded using the ASN.1 basic rules into a
   string of octets.  This, in turn, is encoded as an OCTET STRING, in
   effect "double-wrapping" the original ASN.1 value.

I believe that definition of this class should be:

class Opaque(univ.OctetString):
    tagSet = univ.OctetString.tagSet.tagImplicitly(
        tag.Tag(tag.tagClassApplication, tag.tagFormatSimple, 0x04)
        )

Am I correct?
