Detailed Description

FDv2 polling initializer. Makes a single HTTP GET to the FDv2 polling endpoint, parses the response via the FDv2 protocol state machine, and returns the result.

Threading model: Run() should only be called once at a time. Close() may be called concurrently with Run(). This object may be safely destroyed once no call to Run() or Close() is in progress.

Constructor & Destructor Documentation

FDv2PollingInitializer()

launchdarkly::server_side::data_systems::FDv2PollingInitializer::FDv2PollingInitializer	(	boost::asio::any_io_executor const &	executor,
		Logger const &	logger,
		std::string const &	polling_base_url,
		config::built::HttpProperties const &	http_properties,
		data_model::Selector	selector,
		std::optional< std::string >	filter_key
	)

Constructs an initializer for a single poll request. If filter_key is present, only the specified payload filter is requested.

Member Function Documentation

Close()

void launchdarkly::server_side::data_systems::FDv2PollingInitializer::Close ( )

overridevirtual

Unblocks any in-progress Run() call, causing it to return FDv2SourceResult::Shutdown.

Implements launchdarkly::server_side::data_interfaces::IFDv2Initializer.

Identity()

std::string const & launchdarkly::server_side::data_systems::FDv2PollingInitializer::Identity ( ) const

overridevirtual

Returns

A display-suitable name of the initializer.

Implements launchdarkly::server_side::data_interfaces::IFDv2Initializer.

Run()

async::Future< FDv2SourceResult > launchdarkly::server_side::data_systems::FDv2PollingInitializer::Run ( )

overridevirtual

Returns a Future that resolves with the result once the initializer completes. Called at most once per instance.

Close() may be called from another thread to unblock Run(), in which case the future resolves with FDv2SourceResult::Shutdown.

Implements launchdarkly::server_side::data_interfaces::IFDv2Initializer.
