O2GOffersTable

The class is an in-memory representation of the Offers table.
In order to keep this representation in sync with the trading server, you must instantiate the class and listen to the updates coming from the trading server. The class provides methods to find individual offers, represented by the O2GOfferTableRow.

In order to get offers information for the first time, you must obtain an instance of the class by calling the O2GTableManager.getTable method with the O2GTableType.OFFERS argument. For example,

O2GOffersTable offersTable = (O2GOffersTable)tableManager.getTable(O2GTableType.OFFERS);

In order to keep the O2GOffersTable data current, your application must listen to the Offers table updates coming from the trading server. These updates represent inserts into the table and changes of the offer information. An instance of the class implementing the IO2GTableListener interface must be subscribed to the table updates. Subscription for each update type is done individually. Before the logout, you must unsubscribe the listener from every update type separately. The table below shows the subscription/unsubsription syntax for the O2GOffersTable:

Note: Offers can be deleted only when the market is closed. Therefore, you do not receive updates of the DELETE type during the trading session and there is no need to subscribe to it.
