public void inject(JaegerSpanContext spanContext, io.opentracing.propagation.Binary carrier)
Injector
Called when Tracer.inject(io.opentracing.SpanContext, Format, Object)
is used. It should handle the logic behind injecting propagation scheme
specific information into the carrier (e.g. http request headers, amqp message headers,
etc.).
All exceptions thrown from this method will be caught and logged on ERROR
level so
that business code execution isn't affected. If possible, catch implementation specific
exceptions and log more meaningful information.

spanContext
- span context that should be used to pass trace information with the carriercarrier

public JaegerSpanContext extract(io.opentracing.propagation.Binary carrier)
Extractor
Called when Tracer.extract(io.opentracing.propagation.Format, Object)
is used. It should handle the logic behind extracting propagation-scheme
specific information from carrier (e.g. http request headers, amqp message headers, etc.).
This method must not modify the carrier
All exceptions thrown from this method will be caught and logged on WARN
level so
that business code execution isn't affected. If possible, catch implementation specific
exceptions and log more meaningful information.

- input that you extract Span information from, usually TextMap
