updateOutboundHeaders

default void updateOutboundHeaders(Tracer tracer,

Parameters:

tracer - Tracer used

currentSpan - Context of current span

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

outboundHeaders - Tracing headers map as configured by the tracer
