ark::perf::TracerHost

Defined in header “ark/perf/tracer.hh”.

---

The ’trace host’ singleton. All threads register themselves with this singleton, and the user can query it periodically to get a list of all the completed traces.

Methods

• TracerHost()
  Constructor. Initializes the implementation.

• ~TracerHost()
  Destructor. Defined internally to clear impl_ safely from within the source.

• std::vector< TraceTimingPackPtr > flush()
  Called to query all of the registered threads to fetch their trace packs.

• TracerHostImplementation & impl()
  Called to return the implementation of this host.

• void enable_profiling()
  Set to enable profiling if profiling is off, the traces still execute, but information is not collected anywhere.

• bool profiling_enabled()
  Returns true if profiling is enabled, false otherwise.
