Write Request

Tu je uvedenny sposob prace s write requestom ak sa pouziva priamy potomok EAppChipCard
Existuje aj iny sposob vytvarania requestu napr. TypListka (vytvoril ho T.Bruna)

Vytvorenie write request-u


		EDataCollection			writeCollection;// write request
		EDataCollection			*collection = (EDataCollection*)instanceOfEAppChipCard->GetCollection();// make access to collection with readed data
		EAbstractCardData		*data = (EAbstractCardData*)collection->GetClassByType(TYPE_COMMON_DATA);

		if (!data)
			return someError;//the problem could be that you didn't read TYPE_COMMON_DATA before writing

		data->NodeOut();// take the object out of received collection
		data->SetCardOperation(EAbstractCardData::OPERATION_WRITE);
		// now you have typecast the object to right one
			(ECommonCardDataEN*)data;
			implement here initialization of object
		
		writeCollection.InsertLast(data);

		writeCollection.SetRequestType(EDataCollection::RQ_WRITE);
		writeCollection.SetSNR(serialNumber);// set here serial number of readed card
		mClient->SendDataCollection(&writeCollection);

rozdiel oproti verzii 2.4

kolekcii ktoru posielam je potrebne nastavit typ requestu !!! Zapis !!!
pre jednotlive aplikacne objekty je nutne urcit typ operacie !!! Zapis !!!. Metoda na to sluziaca “SetCardOperation”

              EDataCollection		tmpCollection;

	tmpCollection.SetRequestType(EDataCollection::RQ_WRITE);
	tmpCollection.SetSNR(Aktualne seriove cislo karty);
	EAbstractCardData	*tmpData = "Vytvorim data ktore chcem zapisovat";

	tmpData->SetCardOperation(EAbstractCardData::OPERATION_WRITE);
	tmpCollection.InsertLast(tmpData);

Vytvorenie write request-u pre odjazdenie komercnej zlavy so zapisom (dekrementom) do ponazenky

treba si vsimnut ze sa 3x nastavuje write
na makre ifdef QT_4 je vidiet novu cast kodu

	//get datacollection, we have it saved when the card was approached for reading	
	EDataCollection *dataCollectionForSend = CopyDataCollection(d->mDataCollectionTemp);//copy datacollection
	ECommercialDiscounts *commercialDiscountsForSend = (ECommercialDiscounts*)dataCollectionForSend->GetClassByType(TYPE_COMMERCIAL_DISCOUNT);
 
	//vytiahnem nod z kolekcie
	commercialDiscountsForSend->NodeOut();
 
	//create collection for write
	EDataCollection* dataCollection = new EDataCollection();
	dataCollection->SetSNR(commonCardData->GetSNR());
 
	//ktoru komecnu zlavu som zmenil aby bajvoc vedel co zapisat
	commercialDiscountsForSend->SetIndexToWrite(d->mKomercnaZlavaID);	
 
	//create and set purse, prepare it for decrement
	EPurseData *purseData = new EPurseData();
	purseData->SetSNR(commonCardData->GetSNR());
	purseData->SetValue(commercialDiscountTemp->GetCena());
	purseData->SetPurseChangeType(EPurseData::PURSE_DEC);
 
	#ifdef QT_4
		//nastavim poziadavok na write
		commercialDiscountsForSend->SetCardOperation(EAbstractCardData::OPERATION_WRITE);
		//nastavim aj penazenky na write
		purseData->SetCardOperation(EAbstractCardData::OPERATION_WRITE);
	#endif
	commercialDiscountsForSend->SetPurseData(purseData);//nastav penazenku do komercnych zliav
	//vloz komercne zlavy do  datacolection
	dataCollection->InsertLast(commercialDiscountsForSend);
 
	//wait for card approach to write data on card
	#ifdef QT_4
		dataCollection->SetRequestType(EDataCollection::RQ_WRITE);
		EChipCard::GetInstance().SendAplRequestWrite(dataCollection);
	#else
		EBlCard::GetInstance()->GetEAppChipCard()->SendAplRequestWrite(dataCollection);
	#endif
