Method Detail

convertWingtipsSpanToZipkinSpan

public zipkin.Span convertWingtipsSpanToZipkinSpan(com.nike.wingtips.Span wingtipsSpan,
                                          zipkin.Endpoint zipkinEndpoint,
                                          java.lang.String localComponentNamespace)

Specified by:

convertWingtipsSpanToZipkinSpan in interface WingtipsToZipkinSpanConverter

Parameters:

wingtipsSpan - The Wingtips span to convert.

zipkinEndpoint - The Zipkin Endpoint associated with the current service. This is often a singleton that gets reused throughout the life of the service. Used when creating Zipkin client/server/local annotations.

localComponentNamespace - The Constants.LOCAL_COMPONENT namespace that should be used when creating certain Zipkin annotations when the Wingtips span's Span.getSpanPurpose() is Span.SpanPurpose.LOCAL_ONLY. See the Constants.LOCAL_COMPONENT javadocs for more information on what this is and how it's used by the Zipkin server, so you know what value you should send.

Returns:

The given Wingtips Span after it has been converted to a Span.
