Hello everyone,
i’m trying to write a little macro that exports data to ASCII from certain histogramms of a rootfile. Therefore i browse through all the directories of the rootfile and as soon as the histname matches an entry in my list the histogram is saved. Since i like to do some operations on the data and essentially can do that only after all histograms are found i’d like to store the data in class. And since i have several datasets i want to use a vector of this class. Something like this:
class Particle
{
public:
Particle() {}
Particle(std::string fiName,std::vector<double> counts):path(fiName),raw_counts(counts) {}
double get_RawCounts(int index) {return (index<raw_counts.size())?raw_counts[index]:0.;}
int get_Size() {return raw_counts.size();}
const std::string get_Path() {return path;}
private:
std::vector<double> raw_counts;
std::string path;
};
//_________________________________________________________________________________________________________________________
void SaveCounts(TH1D *hist,std::string name)
{
std::vector<double> vec;
for(int i=1;i <= hist->GetNbinsX();i++)
vec.push_back(hist->GetBinContent(i));
Particle p(name,vec);
for(int i=0;i<p.get_Size();i++)
std::cout << p.get_RawCounts(i) << std::endl;
vector<Particle> counts;
counts.push_back(p); // leads to crash
}The CINT crashes as soon as it invokes the last line.
The strange thing is: if i do basically the same steps by hand it doesn’t crash. So if i enter for example:
string name = "test";
vector<double> dvec;
dvec.push_back(1.2);
Particle p(name,dvec);
vector<Particle> pvec;
pvec.push_back(p);
pvec.push_back(Particle(name,dvec));it will work without any problems.
Any idea what i’m missing
