Table manager vs Non-table manager

Table manager preload all tables to your local memory, it is an in-memory representation of API tables. The table manager allows you to subscribe to table change events such as updates, adding rows, or removing rows. It is important to note that the SummaryTable is only accessible through the table manager. Table manager presents a performance decrease because it is constantly recalculating fields.

Non-table manager allow you to capture table updates adhoc via the use of a class that implements the IO2GResponseListener interface. It give performance advantage but you need to calculate some fields such as PipCost or P/L.

Request Current Balance

You need to request the table from server. Please refer to NonTableManagerSamples\PrintTable example program:

  private static O2GAccountRow GetAccount(O2GSession session)
    O2GResponseReaderFactory readerFactory = session.getResponseReaderFactory();
    if (readerFactory == null)
        throw new Exception("Cannot create response reader factory");
    O2GLoginRules loginRules = session.getLoginRules();
    O2GResponse response = loginRules.getTableRefreshResponse(O2GTableType.Accounts);
    O2GAccountsTableResponseReader accountsResponseReader = readerFactory.createAccountsTableReader(response);
    for (int i = 0; i < accountsResponseReader.Count; i++)
        O2GAccountRow accountRow = accountsResponseReader.getRow(i);
        Console.WriteLine("AccountID: {0}, Balance: {1}", accountRow.AccountID, accountRow.Balance);
    return accountsResponseReader.getRow(0);
