Class Session

    An object encapsulating a Realm Object Server session. Sessions represent the communication between the client (and a local Realm file on disk), and the server (and a remote Realm at a given URL stored on a Realm Object Server). Sessions are always created by the SDK and vended out through various APIs. The lifespans of sessions associated with Realms are managed automatically.

    GetProgressObservable(ProgressDirection, ProgressMode)

    Gets an IObservable<T> that can be used to track upload or download progress.

    Declaration
    public IObservable<SyncProgress> GetProgressObservable(ProgressDirection direction, ProgressMode mode)
    Parameters
    Type Name Description
    ProgressDirection direction

    The transfer direction (upload or download) to track in the subscription callback.
    ProgressMode mode

    The desired behavior of this progress notification block.
    Returns
    Type Description
    IObservable<SyncProgress>

    An observable that you can subscribe to and receive progress updates.
    Remarks

    To start receiving notifications, you should call Subscribe(IObserver<T>) on the returned object. The token returned from Subscribe(IObserver<T>) should be retained as long as progress notifications are desired. To stop receiving notifications, call Dispose() on the token. You don't need to keep a reference to the observable itself. The progress callback will always be called once immediately upon subscribing in order to provide the latest available status information.

    Examples
    class ProgressNotifyingViewModel
{
    private IDisposable notificationToken;

    public void ShowProgress()
    {
        var observable = session.GetProgressObservable(ProgressDirection.Upload, ProgressMode.ReportIndefinitely);
        notificationToken = observable.Subscribe(progress =>
        {
            // Update relevant properties by accessing
            // progress.TransferredBytes and progress.TransferableBytes
        });
    }

    public void HideProgress()
    {
        notificationToken?.Dispose();
        notificationToken = null;
    }
}
    In this example we're using ObservableExtensions.Subscribe found in the Reactive Extensions class library. If you prefer not to take a dependency on it, you can create a class that implements IObserver<T> and use it to subscribe instead.
