Member Function Documentation

FillRequestWithTracingContext()

virtual void tracing::TracingManagerBase::FillRequestWithTracingContext ( const Span & span, clients::http::RequestTracingEditor request ) const

pure virtual

Fill new client requests with tracing information.

Implemented in tracing::GenericTracingManager.

FillResponseWithTracingContext()

virtual void tracing::TracingManagerBase::FillResponseWithTracingContext ( const Span & span, server::http::HttpResponse & response ) const

pure virtual

Fill response with tracing information.

Implemented in tracing::GenericTracingManager.

TryFillSpanBuilderFromRequest()

virtual bool tracing::TracingManagerBase::TryFillSpanBuilderFromRequest ( const server::http::HttpRequest & request, SpanBuilder & span_builder ) const

pure virtual

Fill SpanBuilder params with actual tracing information extracted from the request. You should build Span with SpanBuilder::Build, after calling this.

Returns

Returns bool, that tells us was any of tracing headers used to create new span

Implemented in tracing::GenericTracingManager.
