Method Summary

Modifier and Type	Method and Description
InstrumentationLibraryInfo	getInstrumentationLibraryInfo() Returns the instrumentation library specified when creating the tracer which produced this span.
long	getLatencyNanos() Returns the latency of the Span in nanos.
String	getName() Returns the name of the Span.
io.opentelemetry.trace.SpanContext	getSpanContext() Returns the SpanContext of the Span.
boolean	hasEnded() Returns whether this Span has already been ended.
SpanData	toSpanData() This converts this instance into an immutable SpanData instance, for use in export.

Method Detail

getSpanContext

io.opentelemetry.trace.SpanContext getSpanContext()

Returns the SpanContext of the Span.

Equivalent with Span.getContext().

Returns:

the SpanContext of the Span.

Since:

0.1.0

getName

String getName()

Returns the name of the Span.

The name can be changed during the lifetime of the Span by using the Span.updateName(String) so this value cannot be cached.

Returns:

the name of the Span.

Since:

0.1.0

toSpanData

SpanData toSpanData()

This converts this instance into an immutable SpanData instance, for use in export.

Returns:

an immutable SpanData instance.

Since:

0.1.0

getInstrumentationLibraryInfo

InstrumentationLibraryInfo getInstrumentationLibraryInfo()

Returns the instrumentation library specified when creating the tracer which produced this span.

Returns:

an instance of InstrumentationLibraryInfo describing the instrumentation library

hasEnded

boolean hasEnded()

Returns whether this Span has already been ended.

Returns:

true if the span has already been ended, false if not.

Since:

0.4.0

getLatencyNanos

long getLatencyNanos()

Returns the latency of the Span in nanos. If still active then returns now() - start time.

Returns:

the latency of the Span in nanos.

Since:

0.4.0
