gpg::NearbyConnections::Builder

#include <nearby_connections_builder.h>

Builder class used to construct NearbyConnections objects.

Summary

Constructors and Destructors

Builder()
~Builder()

Public types

OnInitializationFinishedCallback typedef
std::function< void(InitializationStatus)>
A callback that the app invokes on initializing the API, or when initialization fails.
OnLogCallback typedef
std::function< void(LogLevel, const std::string &)>
The type of logging callback that can be provided to the SDK.

Public functions

Create(const PlatformConfiguration & platform)
std::unique_ptr< NearbyConnections >
Specifies the platform for which Builder is to create the NearbyConnections object, and then attempts to create it.
SetClientId(int64_t client_id)
Sets a client ID for this API, which are returned by callbacks.
SetDefaultOnLog(LogLevel min_level)
Specifies that logging should use the DEFAULT_ON_LOG_CALLBACK at the specified log level.
SetOnInitializationFinished(OnInitializationFinishedCallback callback)
Registers a callback that the app calls when initialization finishes.
SetOnLog(OnLogCallback callback, LogLevel min_level)
Registers a callback that will perform logging.
SetOnLog(OnLogCallback callback)
Registers a callback that will perform logging.
SetServiceId(const std::string & service_id)
Sets a service ID used when advertising.

Public types

OnInitializationFinishedCallback

std::function< void(InitializationStatus)> OnInitializationFinishedCallback

A callback that the app invokes on initializing the API, or when initialization fails.

OnLogCallback

std::function< void(LogLevel, const std::string &)> OnLogCallback

The type of logging callback that can be provided to the SDK.

Public functions

Builder

 Builder()

Create

std::unique_ptr< NearbyConnections > Create(
  const PlatformConfiguration & platform
)

Specifies the platform for which Builder is to create the NearbyConnections object, and then attempts to create it.

If successful, it will return a unique_ptr to the NearbyConnections object. For more information, see the documentation on platform configuration.

SetClientId

Builder & SetClientId(
  int64_t client_id
)

Sets a client ID for this API, which are returned by callbacks.

The client ID allows a single object to register as a listener for multiple NearbyConnection instances, and to tell which callbacks are being returned for which instances. This ID does nothing on Android.

SetDefaultOnLog

Builder & SetDefaultOnLog(
  LogLevel min_level
)

Specifies that logging should use the DEFAULT_ON_LOG_CALLBACK at the specified log level.

min_level specifies the minimum log level at which the app invokes the default callback.

Possible levels are: VERBOSE, INFO, WARNING, and ERROR.

This specification is equivalent to calling SetOnLog(OnLogCallback, LogLevel) with OnLogCallback set to DEFAULT_ON_LOG_CALLBACK and a LogLevel of min_level.

SetOnInitializationFinished

Builder & SetOnInitializationFinished(
  OnInitializationFinishedCallback callback
)

Registers a callback that the app calls when initialization finishes.

The app must call it prior to calling Create. The app may invoke the callback multiple times. For example, if a user gets a phone call and then returns to the app, NearbyConnections will reinitialize and then call this callback again.

Note that this callback must be called before you can use a NearbyConnections object.

SetOnLog

Builder & SetOnLog(
  OnLogCallback callback,
  LogLevel min_level
)

Registers a callback that will perform logging.

min_level specifies the minimum log level. In ascending order, possible levels are: VERBOSE, INFO, WARNING, and ERROR.

SetOnLog

Builder & SetOnLog(
  OnLogCallback callback
)

Registers a callback that will perform logging.

This is equivalent to calling SetOnLog(OnLogCallback, LogLevel) with a LogLevel of INFO.

SetServiceId

Builder & SetServiceId(
  const std::string & service_id
)

Sets a service ID used when advertising.

This ID does nothing on Android, but other platforms may require it to be able to advertise.
