Constructor & Destructor Documentation

EventObjectBranchFlattener() [1/2]

EventObjectBranchFlattener ( 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. genEvent, recEvent
nameOut	e.g. Generator, ... (NANOAOD)

        : BranchFlattener(v), branchIn(nullptr)
    {
        using namespace std;
 
        branchIn = flow.GetBranchReadOnly<T>(nameIn, DT::facultative);
        if (!branchIn) return;
 
        Add<double>(flow, nameOut, [this](const T& obj) { return obj.Weight(this->v); });
    }
