public final class ContextPropagationOperator
extends Object

Based on Spring Sleuth's Reactor instrumentation.

Method Summary

Modifier and Type	Method	Description
static ContextPropagationOperatorBuilder	builder()
static ContextPropagationOperator	create()
static io.opentelemetry.context.Context	getOpenTelemetryContext(reactor.util.context.Context context, io.opentelemetry.context.Context defaultTraceContext)	Gets Trace Context from Reactor Context.
void	registerOnEachOperator()	Registers a hook that applies to every operator, propagating Context to downstream callbacks to ensure spans in the Context are available throughout the lifetime of a reactive stream.
void	resetOnEachOperator()	Unregisters the hook registered by registerOnEachOperator().
static <T> reactor.core.publisher.Flux<T>	runWithContext(reactor.core.publisher.Flux<T> publisher, io.opentelemetry.context.Context tracingContext)	Forces Flux to run in traceContext scope.
static <T> reactor.core.publisher.Mono<T>	runWithContext(reactor.core.publisher.Mono<T> publisher, io.opentelemetry.context.Context tracingContext)	Forces Mono to run in traceContext scope.
static reactor.util.context.Context	storeOpenTelemetryContext(reactor.util.context.Context context, io.opentelemetry.context.Context traceContext)	Stores Trace Context in Reactor Context.

Method Details

create

public static ContextPropagationOperator create()

builder

public static ContextPropagationOperatorBuilder builder()

storeOpenTelemetryContext

public static reactor.util.context.Context storeOpenTelemetryContext(reactor.util.context.Context context,
 io.opentelemetry.context.Context traceContext)

Stores Trace Context in Reactor Context.

Parameters:

context - Reactor's context to store trace context in.

traceContext - Trace context to be stored.

getOpenTelemetryContext

public static io.opentelemetry.context.Context getOpenTelemetryContext(reactor.util.context.Context context,
 io.opentelemetry.context.Context defaultTraceContext)

Gets Trace Context from Reactor Context.

Parameters:

context - Reactor's context to get trace context from.

defaultTraceContext - Default value to be returned if no trace context is found on Reactor context.

Returns:

Trace context or default value.

registerOnEachOperator

public void registerOnEachOperator()

Registers a hook that applies to every operator, propagating Context to downstream callbacks to ensure spans in the Context are available throughout the lifetime of a reactive stream. This should generally be called in a static initializer block in your application.

resetOnEachOperator

public void resetOnEachOperator()

Unregisters the hook registered by registerOnEachOperator().

runWithContext

public static <T> reactor.core.publisher.Mono<T> runWithContext(reactor.core.publisher.Mono<T> publisher,
 io.opentelemetry.context.Context tracingContext)

Forces Mono to run in traceContext scope.

runWithContext

public static <T> reactor.core.publisher.Flux<T> runWithContext(reactor.core.publisher.Flux<T> publisher,
 io.opentelemetry.context.Context tracingContext)

Forces Flux to run in traceContext scope.
