	AddHandlers(handlerMap map[string]Handler)

	// AddVerifiers register all the handler for the dynamic config values
	AddVerifiers(verifierMap map[string]Verifier)

	// Refresh relesh the dynamic config client
	Refresh()

	// StartBackGroundRefresh start the back fround refresh for dynamic config
	StartBackGroundRefresh()

	GetOrDefault(fieldName string, defaultValue interface{}) interface{}
}
