Member Function Documentation

Identity()

std::string const & launchdarkly::server_side::data_components::ChangeNotifier::Identity ( ) const

overridevirtual

Returns

Identity of the destination. Used in logs.

Implements launchdarkly::server_side::data_interfaces::IDestination.

Init()

void launchdarkly::server_side::data_components::ChangeNotifier::Init ( data_model::SDKDataSet  data_set )

overridevirtual

Initialize the destination with a base set of data.

Parameters

data_set

The initial data received by the SDK.

Implements launchdarkly::server_side::data_interfaces::IDestination.

OnFlagChange()

std::unique_ptr< IConnection > launchdarkly::server_side::data_components::ChangeNotifier::OnFlagChange ( ChangeHandler  handler )

overridevirtual

Listen for changes to flag configuration. The change handler will be called with a set of affected flag keys. Changes include flags whose dependencies (either other flags, or segments) changed.

Parameters

signal

The handler for the changes.

Returns

A connection which can be used to stop listening.

Implements launchdarkly::server_side::IChangeNotifier.

Upsert() [1/2]

void launchdarkly::server_side::data_components::ChangeNotifier::Upsert ( std::string const &  key, data_model::FlagDescriptor  flag  )

overridevirtual

Upsert a flag named by key.

Parameters

key	Flag key.
flag	Flag descriptor.

Implements launchdarkly::server_side::data_interfaces::IDestination.

Upsert() [2/2]

void launchdarkly::server_side::data_components::ChangeNotifier::Upsert ( std::string const &  key, data_model::SegmentDescriptor  segment  )

overridevirtual

Upsert a segment named by key.

Parameters

key	Segment key.
segment	Segment descriptor.

Implements launchdarkly::server_side::data_interfaces::IDestination.
