TAO_Property_Filter | pfilter_ |
An implementation of CosTrading::OfferIterator IDL interface appropriate when trader has Register functionality.
Stores ids of offers to be iterated over. Before returning an offer, checks if the offer is still there (since it may have been removed by the Register).

Deposit at maximum n offers into the return sequence and return 1, or return 0 if the iterator is done and no offers are returned.
