Detailed Description

template<size_t N>
class anab::MVAWriter< N >

Helper for registering in the art::EDProducer all data products needed for N-output MVA results: keep MVADescriptions<N> for all types T in one collection while separate instance names are used for the MVA output value collections for each type T. Use one instance of this class per one MVA model, applied to one or more types.

Constructor & Destructor Documentation

template<size_t N>

anab::MVAWriter< N >::MVAWriter ( art::EDProducer *  module, const char *  name = ""  )

inline

Name provided to the constructor is used as an instance name for MVADescription<N> and FeatureVector<N> (for which it is combined with the processed data product names). Good idea is to use the name as an indication of what MVA model was used on the data (like eg. "emtrack" for outputs from a model distinguishing EM from track-like hits and clusters). The name is used as an instance name for the MVADescription data product which lets you to save multiple MVA results from a single art module.
