Module: LaunchDarkly::Impl::DataSystem::Initializer

Defined in:
lib/ldclient-rb/impl/data_system.rb

Overview

Mixin that defines the required methods of an initializer implementation. An initializer is a component capable of retrieving a single data result, such as from the LaunchDarkly polling API.

The intent of initializers is to quickly fetch an initial set of data, which may be stale but is fast to retrieve. This initial data serves as a foundation for a Synchronizer to build upon, enabling it to provide updates as new changes occur.

Application code should not need to implement this directly; it is used internally by the SDK.

Since:

  • 5.5.0
