Detailed Description

IDataSynchronizer obtains data via a background synchronization mechanism, updating an IDestination whenever changes arrive from upstream.

Member Function Documentation

Identity()

virtual std::string const & launchdarkly::server_side::data_interfaces::IDataSynchronizer::Identity ( ) const

pure virtual

Returns

Identity of the synchronizer. Used in logs.

Implemented in launchdarkly::server_side::data_systems::PollingDataSource, and launchdarkly::server_side::data_systems::StreamingDataSource.

ShutdownAsync()

virtual void launchdarkly::server_side::data_interfaces::IDataSynchronizer::ShutdownAsync ( std::function< void()>  complete )

pure virtual

Stops the synchronization mechanism. Stop will be called only once after StartAsync. Stop should not block, but should invoke the completion function once shutdown.

Parameters

complete

A callback to be invoked on completion.

Implemented in launchdarkly::server_side::data_systems::PollingDataSource, and launchdarkly::server_side::data_systems::StreamingDataSource.

StartAsync()

virtual void launchdarkly::server_side::data_interfaces::IDataSynchronizer::StartAsync ( IDestination *  destination, data_model::SDKDataSet const *  bootstrap_data  )

pure virtual

Starts synchronizing data into the given IDestination.

The second parameter, boostrap_data, may be nullptr meaning no bootstrap data is present in the SDK and a full synchronization must be initiated.

If bootstrap_data is not nullptr, then it contains data obtained by the SDK during the bootstrap process. The pointer is valid only for this call.

The data may be used to optimize the synchronization process, e.g. by obtaining a diff rather than a full dataset.

Parameters

destination	The destination to synchronize data into. Pointer is invalid after the ShutdownAsync completion handler is called.
bootstrap_data	Optional bootstrap data. Pointer is valid only for this call.

Implemented in launchdarkly::server_side::data_systems::PollingDataSource, and launchdarkly::server_side::data_systems::StreamingDataSource.
