When using the chain method, is there anyway to determine which provider returned the result.

Ex:

$geocoder = new \Geocoder\Geocoder();
$adapter = new \Geocoder\HttpAdapter\CurlHttpAdapter();
$chain = new \Geocoder\Provider\ChainProvider(array(
new \Geocoder\Provider\FreeGeoIpProvider($adapter),
new \Geocoder\Provider\HostIpProvider($adapter),
new \Geocoder\Provider\GoogleMapsProvider($adapter),
new \Geocoder\Provider\BingMapsProvider($adapter, '<API_KEY>'),
new \Geocoder\Provider\OpenStreetMapProvider($adapter),
));
$geocoder->registerProvider($chain);

I want to know if google or bing returned the result set.
