class TMVA::Timer: public TStopwatch


 Timing information for training and evaluation of MVA methods

 Usage:

    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)

 constructor

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 )

 destructor

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
 caution:

TString SecToText(Double_t , Bool_t ) const

 pretty string output

Timer(const char* prefix = "", Bool_t colourfulOutput = kTRUE)
