void trkf::KHitContainer::clear ( )

inherited

Clear all lists.

void trkf::KHitContainerWireX::fill ( const detinfo::DetectorPropertiesData &  detProp, const art::PtrVector< recob::Hit > &  hits, int  only_plane  )

override

Fill container.

Arguments:

hits - RecoBase/Hit collection. only_plane - Choose hits from this plane if >= 0.

This method converts the hits in the input collection into KHitWireX objects and inserts them into the base class. Hits corresponding to the same readout wire are grouped together as KHitGroup objects.
