public method IO2GEachRowListener.onEachRow

Brief

Processes iteration through rows of a table.

Declaration
Java
void  onEachRow (String rowID, O2GRow rowData)

Parameters
rowID

The identifier of a row. The parameter has the value of the row identifier for a specific trading table. For example, for the Accounts table, it has the value of the AccountID field. The complete list of the identifiers is shown below.
rowData

The object representing a row of a table. In order to process the parameter, you need to know what table it belongs to. It can be accomplished by calling the O2GRow.getTableType method. After that, you must cast the parameter to an appropriate class. For example, for a row of the Accounts table, use the O2GAccountTableRow class. The complete list of the classes is shown below.

Summary

O2GSummaryTableRow

O2GSummaryTableRow row = (O2GSummaryTableRow)(rowData);

To get notifications about iteration through each row of a specific table, an instance of the class implementing the IO2GEachRowListener interface must be passed to the O2GTable.forEachRow method as an argument. For example, if you want to get notifications about iteration through the rows of the Trades table, write the following line:

tradesTable.forEachRow(forEachListener);

Note: The returned row contains the current values of fields. The values are not automatically updated. To monitor changes, use IO2GTableListener.onChanged. The row interface is thread-safe. One can use the returned row in different threads without synchronization.

For the method implementation details, see the example below.

Example

Process iteration through the rows of the Trades table [hide]

// Create session which uses table manager
mSession = O2GTransport.createSession();
mSession.useTableManager(O2GTableManagerMode.YES, null);
 
//...
// After the login, get instances of the table manager and Trades table
O2GTableManager tableManager = mSession.getTableManager();
O2GTradesTable tradesTable = (O2GTradesTable)tableManager.getTable(O2GTableType.TRADES);
 
// ...
// Iterate through the rows of the Trades table
EachRowListener eachRowListener = new EachRowListener();
tradesTable.forEachRow(eachRowListener);
 
 
// Implementation of IO2GEachRowListener interface public method onEachRow
public void onEachRow(String rowID, O2GRow rowData) {
    O2GTradeTableRow trade = (O2GTradeTableRow)(rowData);
    System.out.println("Iterating through the row " + rowID);
    System.out.println("TradeID: " + trade.getTradeID() +
                       " Close = " + trade.getClose());
}
