Modifier and Type	Method	Description
protected void	clearAnnotationInfo(AfterDeploymentValidation adv)	Cleans up any data structures created during annotation processing but which are not needed once the CDI container has started.
protected void	processManagedBean(ProcessManagedBean<?> pmb)	Deals with a managed bean that survived vetoing, provided by concrete extension implementations.

static <E extends Member & AnnotatedElement> void	registerMetric(E element, Class<?> clazz, MetricUtil.LookupResult<? extends Annotation> lookupResult)	Deprecated. This method is made public to migrate from metrics1 to metrics2 for gRPC, this should be refactored
protected static void	registerMetricsForAnnotatedSitesFromGrpcTest()	Deprecated.
protected Routing.Builder	registerService(Object adv, BeanManager bm, ServerCdiExtension server)	Registers the service-related endpoint, after security and as CDI initializes the app scope, returning the default routing for optional use by the caller.

Method Detail

registerMetric

@Deprecated
public static <E extends Member & AnnotatedElement> void registerMetric(E element,
                                                                        Class<?> clazz,

Deprecated.

This method is made public to migrate from metrics1 to metrics2 for gRPC, this should be refactored

DO NOT USE THIS METHOD please.

Type Parameters:

E - type of element

Parameters:

element - element

clazz - class

lookupResult - lookup result

registerMetricsForAnnotatedSitesFromGrpcTest

@Deprecated
protected static void registerMetricsForAnnotatedSitesFromGrpcTest()

Deprecated.

For test use only. This method is used from gRPC integration tests and should not be used elsewhere.

processManagedBean

protected void processManagedBean(ProcessManagedBean<?> pmb)

Description copied from class: HelidonRestCdiExtension

Deals with a managed bean that survived vetoing, provided by concrete extension implementations.

The meaning of "process" varies among the concrete implementations. At this point, this base implementation has managed the annotation processing in a general way (e.g., only non-vetoed beans survive) and now delegates to the concrete implementations to actually respond appropriately to the bean and whichever of its members are annotated.

Specified by:

processManagedBean in class HelidonRestCdiExtension<MetricsSupport>

Parameters:

pmb - the managed bean, with at least one annotation of interest to the extension

clearAnnotationInfo

protected void clearAnnotationInfo(@Observes
                                   AfterDeploymentValidation adv)

Description copied from class: HelidonRestCdiExtension

Cleans up any data structures created during annotation processing but which are not needed once the CDI container has started.

Overrides:

clearAnnotationInfo in class HelidonRestCdiExtension<MetricsSupport>

Parameters:

adv - the AfterDeploymentValidation event

recordProducerFields

protected void recordProducerFields(@Observes
                                    ProcessProducerField<? extends Metric,?> ppf)

Records metric producer fields defined by the application. Ignores producers with non-default qualifiers and library producers.

Parameters:

ppf - Producer field.

recordProducerMethods

protected void recordProducerMethods(@Observes
                                     ProcessProducerMethod<? extends Metric,?> ppm)

Records metric producer methods defined by the application. Ignores producers with non-default qualifiers and library producers.

Parameters:

ppm - Producer method.

registerService

protected Routing.Builder registerService(@Observes @Priority(1010) @Initialized(javax.enterprise.context.ApplicationScoped.class)
                                          Object adv,
                                          BeanManager bm,
                                          ServerCdiExtension server)

Description copied from class: HelidonRestCdiExtension

Registers the service-related endpoint, after security and as CDI initializes the app scope, returning the default routing for optional use by the caller.

Overrides:

registerService in class HelidonRestCdiExtension<MetricsSupport>

Parameters:

adv - app-scoped initialization event

bm - BeanManager

server - the ServerCdiExtension

Returns:

default routing
