Detailed Description

BackgroundSync implements the standard Data System which receives data updates from LaunchDarkly as they happen. It updates an in-memory store with the data, and always operates with a complete dataset.

The BackgroundSync system is advantageous because it allows flag evaluations to take place with up-to-date information. However, some environments may be too large to fit in memory, or a direct connection to LaunchDarkly isn't desired, necessitating use of the alternate LazyLoad system.

Member Function Documentation

AllFlags()

std::unordered_map< std::string, std::shared_ptr< data_model::FlagDescriptor > > launchdarkly::server_side::data_systems::BackgroundSync::AllFlags ( ) const

overridevirtual

Get a map of all flags.

Returns

Map of shared pointers to flags.

Implements launchdarkly::server_side::data_interfaces::IStore.

AllSegments()

std::unordered_map< std::string, std::shared_ptr< data_model::SegmentDescriptor > > launchdarkly::server_side::data_systems::BackgroundSync::AllSegments ( ) const

overridevirtual

Get a map of all segments.

Returns

Map of shared pointers to segments.

Implements launchdarkly::server_side::data_interfaces::IStore.

GetFlag()

std::shared_ptr< data_model::FlagDescriptor > launchdarkly::server_side::data_systems::BackgroundSync::GetFlag ( std::string const &  key ) const

overridevirtual

Get the flag named by key. Returns nullptr if no such flag exists.

Parameters

key	Key of the flag.

Returns

Shared pointer to the flag.

Implements launchdarkly::server_side::data_interfaces::IStore.

GetSegment()

std::shared_ptr< data_model::SegmentDescriptor > launchdarkly::server_side::data_systems::BackgroundSync::GetSegment ( std::string const &  key ) const

overridevirtual

Get the segment named by key. Returns nullptr if no such flag exists.

Parameters

key	Key of the segment.

Returns

Shared pointer to the segment.

Implements launchdarkly::server_side::data_interfaces::IStore.

Identity()

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

overridevirtual

Returns

Identity of the system. Used in logs.

Implements launchdarkly::server_side::data_interfaces::IDataSystem.

Initialized()

bool launchdarkly::server_side::data_systems::BackgroundSync::Initialized ( ) const

overridevirtual

Returns

True if the store has ever contained data.

Implements launchdarkly::server_side::data_interfaces::IStore.
