24 // BluetoothBinderFacade provides simple wrappers to call Binder apis.
25 // Each public function returns a tuple of the return type and an integer
26 // representing the pass/fail value of the function. The functions check to see
27 // if the API call is actually possible. If it is the function's tuple will
28 // contain the actual result and an integer that indicates the value passed. If
29 // the function is not possible then there will be a dummy return value in the
30 // first position of the tuple and the second value in the tuple indicates the
31 // value failed. Therefore it is up to the function to decide whether the
32 // expected api call is actually possible before calling it.
33 //
34 // TODO(tturney): Instead of using an integer in the tuple to represent
35 // pass/fail, create a class that properly represents the result of the
36 // function.
