Constructor & Destructor Documentation

template<size_t N>

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

inline

Name provided to the constructor is used as an instance name for FVecDescription<N> and FeatureVector<N> (for which it is combined with the processed data product names). The name is used as an instance name for the FVecDescription data product which lets you to save multiple vector collections from a single art module.
