class TMVA::Timer: public TStopwatch

 Timing information for training and evaluation of MVA methods


    TMVA::Timer timer( Nloops, "MyClassName" );
    for (Int_t i=0; i<Nloops; i++) {
      ... // some code

      // now, print progress bar:
      timer.DrawProgressBar( i );

      // **OR** text output of left time (never both !)
      fLogger << " time left: " << timer.GetLeftTime( i ) << Endl;

    fLogger << "MyClassName" << ": elapsed time: " << timer.GetElapsedTime()
            << Endl;

 Remark: in batch mode, the progress bar is quite ugly; you may
         want to use the text output then

Function documentation

Timer(const char* prefix = "", Bool_t colourfulOutput = kTRUE)
Timer(Int_t ncounts, const char* prefix = "", Bool_t colourfulOutput = kTRUE)
 standard constructor: ncounts gives the total number of counts that
 the loop will iterate through. At each call of the timer, the current
 number of counts is provided by the user, so that the timer can obtain
 the due time from linearly interpolating the spent time.
~Timer( void )
void Init(Int_t ncounts)
 timer initialisation
void Reset( void )
 resets timer
Double_t ElapsedSeconds( void )
 computes elapsed tim in seconds
TString GetElapsedTime(Bool_t Scientific = kTRUE)
 returns pretty string with elaplsed time
TString GetLeftTime(Int_t icounts)
 returns pretty string with time left
void DrawProgressBar()
 draws the progressbar
void DrawProgressBar(TString )
 draws a string in the progress bar
void DrawProgressBar(Int_t , const TString& comment = "")
 draws progress bar in color or B&W
TString SecToText(Double_t , Bool_t ) const
 pretty string output
Timer(const char* prefix = "", Bool_t colourfulOutput = kTRUE)
