The RooThresholdCategory provides a real-to-category mapping defined by a series of thresholds.
void writeToStream(std::ostream &os, bool compact) const override
Write object contents to given stream.

bool addThreshold(double upperLimit, const char *catName, Int_t catIdx=-99999)
Insert threshold at value upperLimit.
value_type evaluate() const override
Calculate and return the value of the mapping function.
