Types

type Processor

type Processor struct {
	// contains filtered or unexported fields
}

func NewProcessor

func NewProcessor(
	flags flags.Common,
	envVars *environment.Variables,
	startupTimer startup.Timer,
	ctx context.Context,
	wg *sync.WaitGroup,
	configUpdated UpdatedStream,
	dic *di.Container,
) *Processor

NewProcessor creates a new configuration Processor

func NewProcessorForCustomConfig

func NewProcessorForCustomConfig(
	flags flags.Common,
	ctx context.Context,
	wg *sync.WaitGroup,
	dic *di.Container) *Processor

func (*Processor) ListenForCustomConfigChanges

func (cp *Processor) ListenForCustomConfigChanges(
	configToWatch interface{},
	sectionName string,
	changedCallback func(interface{}))

ListenForCustomConfigChanges listens for changes to the specified custom configuration section. When changes occur it applies the changes to the custom configuration section and signals the the changes have occurred.

func (*Processor) LoadCustomConfigSection

func (cp *Processor) LoadCustomConfigSection(config interfaces.UpdatableConfig, sectionName string) error

LoadCustomConfigSection loads the specified custom configuration section from file or Configuration provider. Section will be seed if Configuration provider does yet have it. This is used for structures custom configuration in App and Device services

func (*Processor) Process

func (cp *Processor) Process(
	serviceKey string,
	configStem string,
	serviceConfig interfaces.Configuration,
	useSecretProvider bool) error

type ProviderInfo

type ProviderInfo struct {
	// contains filtered or unexported fields
}

ProviderInfo encapsulates the usage of the Configuration Provider information

func NewProviderInfo

func NewProviderInfo(envVars *environment.Variables, providerUrl string) (*ProviderInfo, error)

NewProviderInfo creates a new ProviderInfo and initializes it

func (ProviderInfo) ServiceConfig

func (config ProviderInfo) ServiceConfig() types.ServiceConfig

ServiceConfig returns service configuration for the Configuration Provider

func (ProviderInfo) UseProvider

func (config ProviderInfo) UseProvider() bool

UseProvider returns whether the Configuration Provider should be used or not.

type UpdatedStream

type UpdatedStream chan struct{}

UpdatedStream defines the stream type that is notified by ListenForChanges when a configuration update is received.
