// ServiceControllerRouter: this class is an implementation detail of a
|
|
// nearby::Core class. The latter delegates all of its activities to
|
|
// the former.
|
|
//
|
|
// All the activities are documented in the public API class:
|
|
// cpp/core_v2/core.h
|
|
//
|
|
// In every method, ClientProxy* represents the client app which receives
|
|
// notifications from Nearby Connections service and forwards them to the app.
|
|
// The rest of arguments have the same meaning as the corresponding
|
|
// methods in the definition of nearby::Core API.
|
|
//
|
|
// Every activity is handled the same way:
|
|
// 1) all the arguments to the call are captured by value;
|
|
// 2) the actual processing is scheduled on a private single-threaded executor,
|
|
// which makes locking unnecessary, when internal data is being manipulated.
|
|
// 3) activity handlers are delegating much of their work to an implementation
|
|
// of a ServiceController interface, which does the actual job.
