Interface SpanContext

All Known Implementing Classes:

Span

public interface SpanContext

Adopted from: https://github.com/opentracing/opentracing-java/blob/0.16.0/opentracing-api/src/main/java/io/opentracing/SpanContext.java SpanContext represents Span state that must propagate to descendant Spans and across process boundaries. SpanContext is logically divided into two pieces: (1) the user-level "Baggage" that propagates across Span boundaries and (2) any Tracer-implementation-specific fields that are needed to identify or otherwise contextualize the associated Span instance (e.g., a tuple). The baggageItems() returns the map of user-level "Baggage".

Since:

1.2.0
