IO2GTableManagerListener

The interface provides a method signature to process notifications about table manager status changes.

You can track the O2GTableManagerStatus by using an instance of the class that implements the IO2GTableManagerListener interface. The table manager status is checked asynchronously. Therefore, your application can run without interruption the processes that are not directly dependent on the status of the table manager. For example, if your application requires loading the GUI components, they are loaded without any interruptions.
Note: If you do not require any special processing and can afford a temporal suspension of the main thread, you can track the table manager status by using the O2GTableManager.getStatus method. In this case, the implementation of the IO2GTableManagerListener is not required.

If you want to use the IO2GTableManagerListener interface to track the table manager status, you must create a class that implements the interface. For example,
public class TableManagerListener implements IO2GTableManagerListener{ }

         TableManagerListener managerListener = new TableManagerListener();
         mSession.useTableManager(O2GTableManagerMode.Yes, managerListener);
         //...
         if (managerListener.WaitForTablesLoad())
         {
             O2GTableManager tableManager = mSession.getTableManager();
             //...
         }
