Weight operator()(const CDCFacet &fromFacet, const CDCFacet &toFacet) final
Main filter method returning the weight of the neighborhood relation.
Class representing a triple of neighboring oriented wire with additional trajectory information.
Definition: CDCFacet.h:32
CDCRLWireHit & getStartRLWireHit()
Getter for the first oriented wire hit.
const CDCWire & getEndWire() const
Getter for the wire the third oriented wire hit is based on.
bool isOnWire(const CDCWire &wire) const
Checks if the oriented hit is associated with the give wire.
