All Known Implementing Classes:

B3TextMapCodec, CompositeCodec, TextMapCodec

public interface Injector<T>

You should implement this class if you want to add possibility to inject information about SpanContext that is passed between services in your custom propagation scheme. Otherwise you should probably use built-in TextMapCodec or B3TextMapCodec

Method Summary

Modifier and Type	Method and Description
void	inject(SpanContext spanContext, T carrier) Called when Tracer.inject(...) is used.

Method Detail

inject

void inject(SpanContext spanContext,
            T carrier)

Called when Tracer.inject(...) 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.

Parameters:

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

carrier - holder of data that is used to pass tracing information between processes
