Detailed Description

A tracker of numbers & fractions of events passing sequential cuts.

Constructor & Destructor Documentation

Cutflow()

Rivet::Cutflow::Cutflow ( const std::vector< std::string > &  edges, const std::string &  path = ""  )

inline

Proper constructor using a cutflow name and a list of edges

Note

the constructor will preprend the empty string as a pre-cut step.
