Method Details

builder

public static InfoObserverConfig.Builder builder()

Create a new builder to configure Info observer.

Returns:

a new builder

create

public static InfoObserver create(InfoObserverConfig config)

Create a new Info observer using the provided configuration.

Parameters:

config - configuration

Returns:

a new observer

create

public static InfoObserver create(Consumer<InfoObserverConfig.Builder> consumer)

Create a new Info observer customizing its configuration.

Parameters:

consumer - configuration consumer

Returns:

a new observer

create

public static InfoObserver create()

Create a new Info observer with default configuration.

Returns:

a new observer

prototype

public InfoObserverConfig prototype()

Description copied from interface: Observer

Configuration of this observer.

Specified by:

prototype in interface Observer

Specified by:

prototype in interface RuntimeType.Api<InfoObserverConfig>

Returns:

configuration of the observer

type

public String type()

Description copied from interface: Observer

Type of this observer, to make sure we do not configure an observer both from ServiceLoader and using programmatic approach. If it is desired to have more than one observer of the same type, always use programmatic approach

Specified by:

type in interface NamedService

Specified by:

type in interface Observer

Returns:

type of this observer, should match ObserveProvider.type()

register

public void register(ServerFeature.ServerFeatureContext featureContext,
 List<HttpRouting.Builder> observeEndpointRouting,
 UnaryOperator<String> endpointFunction)

Description copied from interface: Observer

Register the observer features, services, and/or filters. This is used by the observe feature. Do NOT use this method directly, kindly start with ObserveFeature and register it with the server builder.

Specified by:

register in interface Observer

Parameters:

featureContext - access to all routing builders, for cases where this observer needs to register additional components to other sockets

observeEndpointRouting - routing builders that expose observability endpoints, and this feature must use these to register any endpoints exposed for observability

endpointFunction - function to obtain the final endpoint for observers that expose observe endpoints (such as /observe/health would be provider for health by default)
