Detailed Description

Defines a continuous data source that produces a stream of results. Used during the synchronization phase of FDv2, after initialization is complete.

The stream is started lazily on the first call to Next(). The synchronizer runs until Close() is called.

Member Function Documentation

Close()

virtual void launchdarkly::server_side::data_interfaces::IFDv2Synchronizer::Close ( )

pure virtual

Unblocks any in-progress Next() call, causing it to return FDv2SourceResult::Shutdown, and releases underlying resources.

Implemented in launchdarkly::server_side::data_systems::FDv2StreamingSynchronizer, launchdarkly::server_side::data_systems::FDv2PollingSynchronizer, and launchdarkly::server_side::data_systems::FDv1AdapterSynchronizer.

Identity()

virtual std::string const& launchdarkly::server_side::data_interfaces::IFDv2Synchronizer::Identity ( ) const

pure virtual

Returns

A display-suitable name of the synchronizer.

Implemented in launchdarkly::server_side::data_systems::FDv2StreamingSynchronizer, launchdarkly::server_side::data_systems::FDv2PollingSynchronizer, and launchdarkly::server_side::data_systems::FDv1AdapterSynchronizer.

Next()

virtual async::Future<FDv2SourceResult> launchdarkly::server_side::data_interfaces::IFDv2Synchronizer::Next ( data_model::Selector  selector )

pure virtual

Returns a Future that resolves with the next result once it is available.

On the first call, the synchronizer starts its underlying connection. Subsequent calls continue reading from the same connection.

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

Parameters

selector

The selector to send with the request, reflecting any changesets applied since the previous call.

Implemented in launchdarkly::server_side::data_systems::FDv2StreamingSynchronizer, launchdarkly::server_side::data_systems::FDv2PollingSynchronizer, and launchdarkly::server_side::data_systems::FDv1AdapterSynchronizer.
