 used by all histogrammes stays below the limit defined by the user.

Function documentation

Int_t calc(Int_t nDim, Int_t binsx, Int_t binsy = 0)
 Calculates how many bytes in memory will occupy a histogram with
 nDim dimensions and number of bins binsx binsy
Int_t calc1d(TH1F* h1d)
 Calculates how many bytes in memory occupies 1d histogram h1d.
Int_t calc2d(TH2F* h2d)
 Calculates how many bytes in memory occupies 2d histogram h2d.
Bool_t checkVirtual(Int_t nDim, Int_t bisx, Int_t binsy = 0)
 Checks if adding of a new histogram with nDim dimensions and number
 of bins binsx, binsy will cause exceeding of the memory limit.
void check(Int_t* c = 0)
 Scans the container of histogrammes and checks if the total amount of
 memory which they occupy is below fHiMemLimit.
void alarm()
 Alarm message.

{ fHiMemLimit = 50000000; check(); }

{}
void setMemLimit(Int_t alimit)
{ fHiMemLimit = alimit; check(); }
Bool_t isAlarm() const
{ return kAlarm; }
Int_t getMemLimit() const
