IO2GOfferRow

Method/Use

Prerequisites

IO2GOffersTableResponseReader.getRow

This method is used to get the initial offer information after a session with the trading server is established.
This method provides access to a single offer. If you want to receive information about multiple offers, call this method in a loop.

Depending on the trading server settings, the Offers table may or may not be loaded by the server automatically during the login process.
To determine whether the table is loaded or not and what follow-up action is required to get the offer information, use the returned value of the IO2GLoginRules.isTableLoadedByDefault method:

If the table is loaded, you can get the offer information by using the IO2GLoginRules.getTableRefreshResponse method;
Otherwise, you must create a request to load the table by using the IO2GRequestFactory.createRefreshTableRequest method. You must obtain a response to this request by implementing of the IO2GResponseListener.onRequestCompleted method.

Both methods use the IO2GResponse object of the O2GResponseType.GetOffers type.
You must parse this object by using the IO2GOffersTableResponseReader object.

For details, see the example below.

IO2GTablesUpdatesReader.getOfferRow

This method is used to get offer information updates.
This method provides access to a single offer. If you need information about multiple offers, call this method in a loop.

To receive offer information updates, you must implement the IO2GResponseListener.onTablesUpdates method. The received IO2GResponse object is of the O2GResponseType.TablesUpdates type.
You must parse this object by using the IO2GTablesUpdatesReader object.

For details, see the example below.

// Get offers information void getOffers(IO2GSession *session, ResponseListener *responseListener) { O2G2Ptr<IO2GLoginRules> loginRules = session->getLoginRules(); if (loginRules) { // Check if Offers table is loaded automatically if (loginRules->isTableLoadedByDefault(Offers)) { // If table is loaded, use getTableRefreshResponse method O2G2Ptr<IO2GResponse> offersResponse = loginRules->getTableRefreshResponse(Offers); O2G2Ptr<IO2GResponseReaderFactory> responseFactory = session->getResponseReaderFactory(); if (responseFactory) { O2G2Ptr<IO2GOffersTableResponseReader> offersReader = responseFactory->createOffersTableReader(offersResponse); for (int i = 0; i < offersReader->size(); i++) { O2G2Ptr<IO2GOfferRow> offer = offersReader->getRow(i); std::cout << "Instrument = " << offer->getInstrument() << " Bid = " << offer->getBid() << " Ask = " << offer->getAsk() << std::endl; } } } else { // If table is not loaded, use createRefreshTableRequest method O2G2Ptr<IO2GRequestFactory> requestFactory = session->getRequestFactory(); if (requestFactory) { O2G2Ptr<IO2GRequest> request = requestFactory->createRefreshTableRequest(Offers); responseListener->setRequest(request->getRequestID()); session->sendRequest(request); while (!responseListener->isRequestComplete() && !responseListener->isRequestFailed()) uni::Sleep(50); } } } } // Implementation of IO2GResponseListener interface public method onRequestCompleted void ResponseListener::onRequestCompleted(const char *requestID, IO2GResponse *response) { if (mRequestID == requestID) { O2G2Ptr<IO2GResponseReaderFactory> readerFactory = mSession->getResponseReaderFactory(); if (readerFactory) { O2G2Ptr<IO2GOffersTableResponseReader> reader = readerFactory->createOffersTableReader(response); for (int i = 0; i < reader->size(); i++) { O2G2Ptr<IO2GOfferRow> offer = reader->getRow(i); std::cout << " This is a response to your request: \nInstrument = " << offer->getInstrument() << " Bid = " << offer->getBid() << " Ask = " << offer->getAsk() << std::endl; } } } } // Implementation of IO2GResponseListener interface public method onTablesUpdates void ResponseListener::onTablesUpdates(IO2GResponse *response) { O2G2Ptr<IO2GResponseReaderFactory> factory = mSession->getResponseReaderFactory(); if (factory) { O2G2Ptr<IO2GTablesUpdatesReader> updatesReader = factory->createTablesUpdatesReader(response); for (int i = 0; i < updatesReader->size(); i++) { if (updatesReader->getUpdateTable(i) == Offers) { O2G2Ptr<IO2GOfferRow> offer = updatesReader->getOfferRow(i); std::cout << " This is a live update: \nInstrument = " << offer->getInstrument() << " Bid = " << offer->getBid() << " Ask = " << offer->getAsk() << std::endl; } } } }
