O2GOfferRow

Method/Use

Prerequisites

O2GOffersTableResponseReader.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 a 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 O2GLoginRules.isTableLoadedByDefault method:

If the table is loaded, you can get the offer information by using the O2GLoginRules.getTableRefreshResponse method;
Otherwise, you must create a request to load the table by using the O2GRequestFactory.createRefreshTableRequest method. You must obtain a response to this request by implementing of the IO2GResponseListener.onRequestCompleted method.

Both the methods use the O2GResponse object of the O2GResponseType.GET_OFFERS type.
You must parse this object by using the O2GOffersTableResponseReader object.

For details, see the example below.

O2GTablesUpdatesReader.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 the offer information updates, you must implement the IO2GResponseListener.onTablesUpdates method. The received O2GResponse object is of the O2GResponseType.TABLES_UPDATES type.
You must parse this object by using the O2GTablesUpdatesReader object.

For details, see the example below.

// Get offers information public static void getOffers(O2GSession session, ResponseListener responseListener) { try { O2GLoginRules loginRules = session.getLoginRules(); // Check if Offers table is loaded automatically if (loginRules != null && loginRules.isTableLoadedByDefault(O2GTableType.OFFERS)) { // If table is loaded, use getTableRefreshResponse method O2GResponse offersResponse = loginRules.getTableRefreshResponse(O2GTableType.OFFERS); O2GResponseReaderFactory responseFactory = session.getResponseReaderFactory(); if (responseFactory == null) { return; } O2GOffersTableResponseReader offersReader = responseFactory.createOffersTableReader(offersResponse); for (int i = 0; i < offersReader.size(); i++) { O2GOfferRow offer = offersReader.getRow(i); System.out.println("AccountID = " + offer.getInstrument() + " Bid = " + offer.getBid() + " Ask = " + offer.getAsk()); } } else { // If table is not loaded, use createRefreshTableRequest method O2GRequestFactory requestFactory = session.getRequestFactory(); if (requestFactory != null) { O2GRequest request = requestFactory.createRefreshTableRequest(O2GTableType.OFFERS); responseListener.setRequest(request.getRequestId()); session.sendRequest(request); Thread.sleep(1000); } } } catch (Exception e) { System.out.println("Exception in getOffers().\n\t " + e.getMessage()); } } // Implementation of IO2GResponseListener interface public method onRequestCompleted public void onRequestCompleted(String requestID, O2GResponse response) { if (requestID.equals(mRequestID)) { O2GResponseReaderFactory readerFactory = mSession.getResponseReaderFactory(); if (readerFactory == null) { return; } O2GOffersTableResponseReader reader = readerFactory.createOffersTableReader(response); for (int i = 0; i < reader.size(); i++) { O2GOfferRow offer = reader.getRow(i); System.out.println(" This is a response to your request: \nInstrument = " + offer.getInstrument() + " Bid = " + offer.getBid() + " Ask = " + offer.getAsk()); } } } // Implementation of IO2GResponseListener interface public method onTablesUpdates public void onTablesUpdates(O2GResponse response) { O2GResponseReaderFactory factory = mSession.getResponseReaderFactory(); if (factory == null) { return; } O2GTablesUpdatesReader updatesReader = factory.createTablesUpdatesReader(response); for (int i = 0; i < updatesReader.size(); i++) { O2GTableType tableType = updatesReader.getUpdateTable(i); if (tableType == O2GTableType.OFFERS) { O2GOfferRow offer = updatesReader.getOfferRow(i); System.out.println(" This is a live update: \nInstrument = " + offer.getInstrument() + " Bid = " + offer.getBid() + " Ask = " + offer.getAsk()); } } }
