No.

Two reasons:
   a)   The dataset handler knows which rows exist, and hence
         the list of valid OIDs.  It will automatically convert
          GETNEXT requests into the appropriate GET request.
          It's this GET request that is passed to your handler.

  b)   Even without this mapping, it's impossible for the agent
         to distinguish between a single GETNEXT request, and
         the start of a walk.   They'll look identical.
