Class: FeatureHub::Sdk::LocalYamlStore

Inherits:
RawUpdateFeatureListener show all
Defined in:
lib/feature_hub/sdk/local_yaml_store.rb

Overview

Reads feature flags from a local YAML file and loads them into a FeatureHubRepository, allowing the SDK to operate without a FeatureHub Edge server. Implements RawUpdateFeatureListener but silently ignores all incoming update callbacks —the file is the single source of truth and is read exactly once at initialization.

Expected YAML format (same as LocalYamlValueInterceptor):

flagValues:
  MY_FLAG: true
  MY_STRING: "hello"
  MY_NUMBER: 42
