DownloaderTask - How to download data for a watchlist

I have seen no examples or documentation that I could use to help understand the DownloaderTask functions and to see whether I could use the DownloadData function to specify an internal list (e.g. a watchlist) to download data for.
Is this possible ?
Also is there an API reference for DownloadTask functions ?

Thanks
Dev

Hi Dev,

Note that DownloaderTask is just a class to check the progress of the downloading process.
Here is an example of how to use DownloadData to download symbols in a specific watchlist.

String[] symbols = Watchlist.GetSymbols("Watchlist Name");
DownloaderTask task = Downloader.DownloadData("", "downloader name", false, symbols, null);
while(!task.IsCompleted)
{
App.Main.Sleep(1000);
}

// Downloading completed
