class IO2GAccountsTableResponseReader

Brief

The class reads a stream of account rows coming from the trading server.

Details

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 IO2GResponse object of the GetAccounts type comes from the trading server as a response to a request for the initial account information. The response consists of the Accounts table rows. Every row is represented by an IO2GAccountRow object. In order to read this response, you must use the O2GAccountsTableResponseReader.

Getting the response

If your application uses the IO2GTableManager, the Accounts table is always loaded during the login process. This information is kept in an IO2GAccountsTable object.

If your application does not use the IO2GTableManager, the initial account information needs to be requested.
Depending on the trading server settings, the Accounts 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 GetAccounts response, use the returned value of the IO2GLoginRules.isTableLoadedByDefault method:

Instantiating the class

An instance of the O2GAccountsTableResponseReader class can be obtained by calling the IO2GResponseReaderFactory.createAccountsTableReader method. For example:

O2G2Ptr<IO2GResponseReaderFactory> responseFactory = session->getResponseReaderFactory();
if (responseFactory)
{
O2G2Ptr<IO2GAccountsTableResponseReader> accountsReader = responseFactory->createAccountsTableReader(accountsResponse);
...
}

Example

        O2G2Ptr<IO2GResponse> accountsResponse = loginRules->getTableRefreshResponse(Accounts);
        O2G2Ptr<IO2GResponseReaderFactory> responseFactory = session->getResponseReaderFactory();
        if (responseFactory)
        {
            O2G2Ptr<IO2GAccountsTableResponseReader> accountsReader = responseFactory->createAccountsTableReader(accountsResponse);
            for (int i = 0; i < accountsReader->size(); ++i)
            {
                O2G2Ptr<IO2GAccountRow> account = accountsReader->getRow(i);
                std::cout << "AccountID: " << account->getAccountID() <<
                             " Balance = " << account->getBalance() <<
                             " UsedMargin = " << account->getUsedMargin() << std::endl;
            }
        }
