Method Detail

scopePassingSpanOperator

public static <T> Function<? super org.reactivestreams.Publisher<T>,? extends org.reactivestreams.Publisher<T>> scopePassingSpanOperator(org.springframework.context.ConfigurableApplicationContext springContext)

Return a span operator pointcut given a Tracing. This can be used in reactor via Flux.transform(Function), Mono.transform(Function), Hooks.onLastOperator(Function) or Hooks.onLastOperator(Function). The Span operator pointcut will pass the Scope of the Span without ever creating any new spans.

Type Parameters:

T - an arbitrary type that is left unchanged by the span operator

Parameters:

springContext - the Spring context.

Returns:

a new lazy span operator pointcut

onEachOperatorForOnEachInstrumentation

public static <T> Function<? super org.reactivestreams.Publisher<T>,? extends org.reactivestreams.Publisher<T>> onEachOperatorForOnEachInstrumentation(org.springframework.context.ConfigurableApplicationContext springContext)

Creates scope passing span operator which applies only to not Scannable.Attr.RunStyle.SYNC Publishers. Used by InstrumentationType#DECORATE_ON_EACH

Type Parameters:

T - an arbitrary type that is left unchanged by the span operator.

Parameters:

springContext - the Spring context.

Returns:

operator to apply to Hooks.onEachOperator(Function).

springContextSpanOperator

public static <T> Function<? super org.reactivestreams.Publisher<T>,? extends org.reactivestreams.Publisher<T>> springContextSpanOperator(org.springframework.context.ConfigurableApplicationContext springContext)

Creates a context with beans in it.

Type Parameters:

T - an arbitrary type that is left unchanged by the span operator

Parameters:

springContext - spring context

Returns:

a new operator pointcut that has beans in the context

onLastOperatorForOnEachInstrumentation

public static <T> Function<? super org.reactivestreams.Publisher<T>,? extends org.reactivestreams.Publisher<T>> onLastOperatorForOnEachInstrumentation(org.springframework.context.ConfigurableApplicationContext springContext)

Creates tracing context capturing reactor operator. Used by InstrumentationType#DECORATE_ON_EACH.

Type Parameters:

T - an arbitrary type that is left unchanged by the span operator.

Parameters:

springContext - the Spring context.

Returns:

operator to apply to Hooks.onLastOperator(Function) for InstrumentationType#DECORATE_ON_EACH

scopePassingOnScheduleHook

public static Function<Runnable,Runnable> scopePassingOnScheduleHook(org.springframework.context.ConfigurableApplicationContext springContext)
