 // The BluetoothAdapter class represents a local Bluetooth adapter which
 // may be used to interact with remote Bluetooth devices. As well as
 // providing support for determining whether an adapter is present, and
 // whether the radio is powered, this class also provides support for
 // obtaining the list of remote devices known to the adapter, discovering
 // new devices, and providing notification of updates to device information.
 //
 // The class may be instantiated for either a specific adapter, or for the
 // generic "default adapter" which may change depending on availability.
