Package io.opentelemetry.api.trace.propagation

Class W3CTraceContextPropagator

java.lang.Object

io.opentelemetry.api.trace.propagation.W3CTraceContextPropagator

All Implemented Interfaces:

io.opentelemetry.context.propagation.TextMapPropagator

@Immutable
public final class W3CTraceContextPropagator
extends Object
implements io.opentelemetry.context.propagation.TextMapPropagator

Implementation of the W3C TraceContext propagation protocol. See W3C Trace Context.

This is the default propagator for SpanContexts. The SpanContext type is designed to support all the data propagated via W3C propagation natively.
