O2GOffersTableResponseReader

All data from the trading server come in the form of responses. The type of the response depends on the type of the request. An O2GResponse object of the type GET_OFFERS comes from the trading server as a response to a request for the initial offer information. The response consists of the Offers table rows. Every row is represented by an O2GOfferRow object. In order to read this response you must use the O2GOffersTableResponseReader.

If your application uses the O2GTableManager, the Offers table is always loaded during the login process. This information is kept in an O2GOffersTable object.

If your application does not use the O2GTableManager, the initial offer information needs to be requested.
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 obtain the GET_OFFERS response, use the returned value of the O2GLoginRules.isTableLoadedByDefault method with the O2GTableType.OFFERS argument:

O2GResponseReaderFactory responseFactory = session.getResponseReaderFactory();

O2GOffersTableResponseReader offersReader = responseFactory.createOffersTableReader(offersResponse);
