Public Member Functions
template<class AState >
	CKFResult (const std::vector< TrackFindingCDC::WithWeight< const AState * >> &path, const genfit::MeasuredStateOnPlane &mSoP)
	Constructor from the path of the result and the final mSoP, which defines the track position of the resulting track.
const std::vector< const AHit * > &	getHits () const
	Getter for the stored hits.
const ASeed *	getSeed () const
	Getter for the stored seeds.
double	getChi2 () const
	Getter for the chi2.

Detailed Description

template<class ASeed, class AHit>
class Belle2::CKFResult< ASeed, AHit >

Object for temporary storage of a CKF tree search result.

It stores the seed together with the associated hits and a chi2 value. This object will not be stored to the DataStore, but is only for internal usage.

All sub-detector CKFs should inherit their own object from this.
