Class Documentation

class NoopSpan : public opentelemetry::trace::Span

No-op implementation of Span. This class should not be used directly.

Public Functions

inline explicit NoopSpan(const std::shared_ptr<Tracer> &tracer) noexcept

inline explicit NoopSpan(const std::shared_ptr<Tracer> &tracer, nostd::unique_ptr<SpanContext> span_context) noexcept

inline virtual void SetAttribute(nostd::string_view, const common::AttributeValue&) noexcept override

Sets an attribute on the Span (ABI).

If the Span previously contained a mapping for the key, the old value is replaced.

inline virtual void AddEvent(nostd::string_view) noexcept override

inline virtual void AddEvent(nostd::string_view, common::SystemTimestamp) noexcept override

inline virtual void AddEvent(nostd::string_view, const common::KeyValueIterable&) noexcept override

inline virtual void AddEvent(nostd::string_view, common::SystemTimestamp, const common::KeyValueIterable&) noexcept override

inline virtual void SetStatus(StatusCode, nostd::string_view) noexcept override

inline virtual void UpdateName(nostd::string_view) noexcept override

inline virtual void End(const EndSpanOptions&) noexcept override

Mark the end of the Span. Only the timing of the first End call for a given Span will be recorded, and implementations are free to ignore all further calls.

Parameters:

options – can be used to manually define span properties like the end timestamp

inline virtual bool IsRecording() const noexcept override

inline virtual SpanContext GetContext() const noexcept override
