-// The BluetoothAdapterChromeOS class implements BluetoothAdapter for the

-// All methods are called from the dbus origin / UI thread and are generally

-//
-// This class interacts with sockets using the BluetoothSocketThread to ensure
-// single-threaded calls, and posts tasks to the UI thread.
-//
-// Methods tolerate a shutdown scenario where BluetoothAdapterChromeOS::Shutdown
-// causes IsPresent to return false just before the dbus system is shutdown but
-// while references to the BluetoothAdapterChromeOS object still exists.
-//
-// When adding methods to this class verify shutdown behavior in
-// BluetoothChromeOSTest, Shutdown.
