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

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 ( 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.

template<class MAP_LOCK_TYPE >

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.

Member Data Documentation

template<class MAP_LOCK_TYPE >

TAO_Offer_Database<MAP_LOCK_TYPE>& TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::db_

private

A reference to the trader is needed for access to the map of offers.

template<class MAP_LOCK_TYPE >

TAO_String_Queue TAO_Register_Offer_Iterator< MAP_LOCK_TYPE >::offer_ids_

private

Offer ids of offers to iterate over.
