Constructor & Destructor Documentation

◆ Report()

G4UA::G4SimTimer::Report::Report ( )

Initializes the variables.

Definition at line 16 of file G4SimTimer.cxx.

17 : nEvent(0), eventTime(0), eventTimeSquared(0)

18 {}

Member Function Documentation

◆ meanAndSigma()

std::pair< double, double > G4UA::G4SimTimer::Report::meanAndSigma ( )

Calculate the mean and sample std dev.

Definition at line 23 of file G4SimTimer.cxx.

   {
     double mean = nEvent > 0 ? eventTime / nEvent : -1.;
     double sigma = -1.;
     if(nEvent > 1)
       sigma = sqrt( (eventTimeSquared/nEvent - mean*mean) / (nEvent-1) );
     return std::make_pair(mean, sigma);
   }

◆ merge()

void G4UA::G4SimTimer::Report::merge ( const Report & rep )

inline

Definition at line 60 of file G4SimTimer.h.

                                  {
       nEvent += rep.nEvent;
       eventTime += rep.eventTime;
       eventTimeSquared += rep.eventTimeSquared;
     }

Member Data Documentation

◆ eventTime

double G4UA::G4SimTimer::Report::eventTime

Accumulated event time.

Definition at line 54 of file G4SimTimer.h.

◆ eventTimeSquared

double G4UA::G4SimTimer::Report::eventTimeSquared

Accumulated squared event time.

Definition at line 56 of file G4SimTimer.h.

◆ nEvent

unsigned int G4UA::G4SimTimer::Report::nEvent

Number of timed G4 events (we skip the first).

Might want to use a larger int type.
