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).

template<class MAP_LOCK_TYPE>
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.

template<class MAP_LOCK_TYPE>
TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::~TAO_Register_Offer_Iterator void   )  [virtual]
 

Destructor.


Member Function Documentation

template<class MAP_LOCK_TYPE>
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.

template<class MAP_LOCK_TYPE>
CORBA::ULong TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::max_left ACE_ENV_SINGLE_ARG_DECL_NOT_USED   )  throw (CORBA::SystemException, CosTrading::UnknownMaxLeft) [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.

template<class MAP_LOCK_TYPE>
CORBA::Boolean TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::next_n CORBA::ULong  n,
CosTrading::OfferSeq_out offers  ACE_ENV_ARG_DECL_NOT_USED
throw (CORBA::SystemException) [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.
