Constructor & Destructor Documentation

ScaledObjectBranchFlattener() [1/2]

ScaledObjectBranchFlattener ( Tools::Flow &  flow, const Variation &  v, const std::string &  nameIn, const std::string &  nameOut  )

inline

Generic class to project vectors of a given scaled object.

Parameters

nameIn	e.g. genJet, recJet (Darwin)
nameOut	e.g. GenJet, Jet (NANOAOD)

        : BranchFlattener(v), branchIn(nullptr)
    {
        using namespace std;
 
        branchIn = flow.GetBranchReadOnly<vector<T>>(nameIn, DT::facultative);
        if (!branchIn) return;
 
        Add<float>(flow, nameOut + "_pt"  , [this](const T& el) { return el.CorrP4(this->v).pt  (); });
        Add<float>(flow, nameOut + "_eta" , [this](const T& el) { return el.CorrP4(this->v).eta (); });
        Add<float>(flow, nameOut + "_phi" , [this](const T& el) { return el.CorrP4(this->v).phi (); });
        Add<float>(flow, nameOut + "_mass", [this](const T& el) { return el.CorrP4(this->v).mass(); });
 
        auto getMult = [](const vector<T>& branchIn) { return branchIn.size(); };
        multiplicity = make_unique<DT::SelfAwarePlainBranch<int, const vector<T>&>>(flow, "n" + nameOut, getMult);
