Description copied from interface: TracerProvider

Update headers for outbound requests. The outboundHeaders already contain injected from tracer via Tracer.inject(SpanContext, Format, Object). This is to enable fine grained tuning of propagated headers for each implementation.

Specified by:

updateOutboundHeaders in interface TracerProvider

Parameters:

currentSpan - Current span covering the outbound call

tracer - Tracer used

parentSpan - Parent span context (may be null)

outboundHeaders - Tracing headers map as configured by the tracer

inboundHeaders - Existing inbound headers (may be empty if not within a scope of a request)

Returns:

new map of outbound headers, defaults to tracing headers
