 // This class pairs with DownloadController on Java side to forward requests
 // for GET downloads to the current DownloadListener. POST downloads are
 // handled on the native side.
 //
 // Both classes are Singleton classes. C++ object owns Java object.
 //
 // Call sequence
 // GET downloads:
-// DownloadController::NewGetDownload() =>
+// DownloadControllerAndroid::CreateGETDownload() =>
 // DownloadController.newHttpGetDownload() =>
 // DownloadListener.onDownloadStart() /
 // DownloadListener2.requestHttpGetDownload()
