// BluetoothDiscoverySession represents a current active or inactive device
// discovery session. Instances of this class are obtained by calling
// BluetoothAdapter::StartDiscoverySession. The Bluetooth adapter will be
// constantly searching for nearby devices, as long as at least one instance
// of an active BluetoothDiscoverySession exists. A BluetoothDiscoverySession is
// considered active, as long as the adapter is discovering AND the owner of the
// instance has not called BluetoothDiscoverySession::Stop. A
// BluetoothDiscoverySession might unexpectedly become inactive, if the adapter
// unexpectedly stops discovery. Users can implement the
// AdapterDiscoveringChanged method of the BluetoothAdapter::Observer interface
// to be notified of such a change and promptly request a new
// BluetoothDiscoverySession if their existing sessions have become inactive.
