Detailed Description
template<class MAP_LOCK_TYPE>
class TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >
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).
Constructor & Destructor Documentation
| TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::TAO_Register_Offer_Iterator | ( | TAO_Offer_Database< MAP_LOCK_TYPE > & | db, |
| const TAO_Property_Filter & | pfilter | ||
| ) |
Takes service type and trader reference in order to later locate offers using their ids.
| TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::~TAO_Register_Offer_Iterator | ( | void | ) | [virtual] |
Destructor.
Member Function Documentation
| void TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::add_offer | ( | CosTrading::OfferId | id, |
| const CosTrading::Offer * | |||
| ) | [virtual] |
Add an offer the iterator should iterate over.
Implements TAO_Offer_Iterator.
| CORBA::ULong TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::max_left | ( | void | ) | [virtual] |
Throws CosTrading::UnknownMaxLeft since with the presence of "Register" functionality, the iterator cannot guarantee that the trader will have all the offers it has now when the time to return them comes.
Implements TAO_Offer_Iterator.
| CORBA::Boolean TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::next_n | ( | CORBA::ULong | n, |
| CosTrading::OfferSeq_out | offers | ||
| ) | [virtual] |
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.
Implements TAO_Offer_Iterator.
