public class OneGetPdu
extends GetPdu

The OneGetPdu class will ask for one (1) object (OID), based on the Get request.

Unless an exception occurred the Object to the update() method of the Observer will be a varbind, so any AsnObject type can be returned. In the case of an exception, that exception will be passed.

For SNMPv3: The receiver of a request PDU acts as the authoritative engine.
