Detailed Description

A simple interface for integrating online accounts access and monitoring into scopes.

Each instantiation of this class targets a particular account service as specified on construction.

Member Typedef Documentation

typedef std::function<void(ServiceStatus const&)> unity::scopes::OnlineAccountClient::ServiceUpdateCallback

Function signature for the service update callback.

Member Enumeration Documentation

enum unity::scopes::OnlineAccountClient::MainLoopSelect

Indicates whether an external main loop already exists, or one should be created internally.

A running main loop is essential in order to receive service updates from the online accounts backend. When in doubt, set to CreateInternalMainLoop.

Enumerator
RunInExternalMainLoop	An external main loop already exists and is running.
CreateInternalMainLoop	An external main loop does not exist.

enum unity::scopes::OnlineAccountClient::PostLoginAction

Indicates what action to take when the login process completes.

Enumerator
Unknown	An action unknown to the run-time was used.
DoNothing	Simply return to the scope with no further action.
InvalidateResults	Invalidate the scope results.
ContinueActivation	Continue with regular result / widget activation.
LastActionCode_	Dummy end marker.

Constructor & Destructor Documentation

unity::scopes::OnlineAccountClient::OnlineAccountClient	(	std::string const &	service_name,
		std::string const &	service_type,
		std::string const &	provider_name,
		MainLoopSelect	main_loop_select = `CreateInternalMainLoop`
	)

Create OnlineAccountClient for the specified account service.

Parameters

service_name	The name of the service (E.g. "com.ubuntu.scopes.youtube_youtube").
service_type	The type of service (E.g. "sharing").
provider_name	The name of the service provider (E.g. "google").
main_loop_select	Indicates whether or not an external main loop exists (see OnlineAccountClient::MainLoopSelect).

Member Function Documentation

std::vector< OnlineAccountClient::ServiceStatus > unity::scopes::OnlineAccountClient::get_service_statuses ( )

Get statuses for all services matching the name, type and provider specified on construction.

Returns: A list of service statuses.

void unity::scopes::OnlineAccountClient::refresh_service_statuses ( )

Refresh all service statuses.

WARNING: If a service update callback is set, this method will invoke that callback for each service monitored. Therefore, DO NOT call this method from within your callback function!

void unity::scopes::OnlineAccountClient::register_account_login_item	(	Result &	result,
