void lar_content::CheatingNeutrinoIdTool::SelectOutputPfos ( const pandora::Algorithm *const  pAlgorithm, const SliceHypotheses &  nuSliceHypotheses, const SliceHypotheses &  crSliceHypotheses, pandora::PfoList &  selectedPfos  )

virtual

Select which reconstruction hypotheses to use; neutrino outcomes or cosmic-ray muon outcomes for each slice.

Parameters

pAlgorithm	the address of the master instance, used to access MCParticles when in training mode
nuSliceHypotheses	the parent pfos representing the neutrino outcome for each slice
crSliceHypotheses	the parent pfos representing the cosmic-ray muon outcome for each slice
sliceNuPfos	to receive the list of selected pfos

Implements lar_content::CheatingSliceIdBaseTool.
