- 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
SpanContext
s. TheSpanContext
type is designed to support all the data propagated via W3C propagation natively.
