Detailed Description

The context for recording a distributed trace associated with a given request.

Member Function Documentation

virtual void net_instaweb::RequestTrace::TraceLiteral ( const char *  literal)
pure virtual

Logs a literal C string to the tracing context. The literal has indefinite lifespan (ie it must be a compile time constant); use TraceString if your data has a bounded lifetime.

bool net_instaweb::RequestTrace::tracing_enabled ( )

Returns true iff tracing is enabled. This can be used to avoid virtual function call overhead in the common case that tracing is not active for a given request.
