Class HTraceToZipkinConverter

java.lang.Object

org.htrace.zipkin.HTraceToZipkinConverter

public class HTraceToZipkinConverter
extends Object

This class is responsible for converting a HTrace.Span to a Zipkin.Span object. To use the Zipkin infrastructure (collector, front end), we need to store the Span information in a zipkin specific format. This class transforms a HTrace:Span object to a Zipkin:Span object.

This is how both Span objects are related:

HTrace:Span	Zipkin:Span
TraceId	TraceId
ParentId	ParentId
SpanId	id
Description	Name
startTime, stopTime	Annotations (cs, cr, sr, ss)
Other annotations	Annotations
