IO2GOfferTableRow

The class represents a single row of the Offers table. In addition to the methods of its parent class, the O2GOfferTableRow class provides methods to access calculated fields, such as cost of one pip per lot.

O2GOffersTable offersTable = (O2GOffersTable)tableManager.getTable(O2GTable.Offers);

If you need access to the current offer information, get an instance of the class by calling any of the following methods of the IO2GOffersTable class:

If you want to track the Offers table updates, your application must have a listener class that implements the IO2GTableListener interface. An instance of the listener class must be subscribed to the table updates. Subscription to each update type is done individually. Before the logout, you must unsubscribe the listener from each update type separately. The examples of subscription/unsubscription syntax are listed below.

To instantiate the O2GOfferTableRow class, you must cast the rowData parameter of the above methods to the O2GOfferTableRow type. For example,

    // Get the instance of table manager
    O2G2Ptr<IO2GTableManager> tableManager = mSession->getTableManager();
