void __attribute__::Init	(	std::vector< KFParticle > &	particles,
		std::vector< int > *	pdg = `0`,
		std::vector< int > *	nPixelHits = `0`
	)

Copies provided particles to the vector KFParticleTopoReconstructor::fTracks assuming a given PDG hypothesis for each particle. If pointer to pdg-vector is not provided "-1" PDG is assigned to each input particle. If pointer to number of precise measurements is provided then this field of KFPTrackVector is also initialised. Only tracks at the first hit position are initialised by this method. The KFParticleTopoReconstructor::fKFParticlePVReconstructor is initialised with the copied tracks.

Parameters

[in]	particles	- vector with input particles (tracks)
[in]	pdg	- pointer to the vector with PDG hypothesis for each track, if pointer is not provided "-1" is set as the pdg hypothesis for all tracks
[in]	nPixelHits	- pointer to the vector with number of precise measurement in each track

Here is the caller graph for this function:

void __attribute__::Init	(	const KFPTrackVector *	particles,
		const std::vector< KFParticle > &	pv
	)

Initialises the pointer KFParticleTopoReconstructor::fTracks with the external pointer "particles". Primary vertices are assumed to be found and are also provided externally. Only reconstruction of short-lived particles should be run if this initialisation method is used. After reconstruction of short-lived particles the KFParticleTopoReconstructor::DeInit() method should be called, otherwise an external memory will be released that can lead to the memory corruption and segmentation fault.

Parameters

[in]	particles	- pointer to the external vectors with input tracks
[in]	pv	- vector with externally reconstructed primary vertex candidates

void __attribute__::Init	(	KFPTrackVector &	tracks,
		KFPTrackVector &	tracksAtLastPoint
	)

Initialises tracks at the first and last hit positions. The KFParticleTopoReconstructor::fKFParticlePVReconstructor is initialised with the copied tracks at the first hit position.

Parameters

[in]	tracks	- vector with the tracks at the first hit position
[in]	tracksAtLastPoint	- vector with the tracks at the last hit position

KFPTrackVector fTracks

Pointer to the array with the input tracks. Memory is allocated by the Init() functions. For reconstruction of primary vertex candidates unsorted tracks are used. For reconstruction of short-lived particles Tracks should be sorted by the KFParticleTopoReconstructor::SortTracks() function. The tracks after sorting are divided into several groups:
0) secondary positive at the first hit position;
1) secondary negative at the first hit position;
2) primary positive at the first hit position;
3) primary negative at the first hit position;
4) secondary positive at the last hit position;
5) secondary negative at the last hit position;
6) primary positive at the last hit position;
7) primary negative at the last hit position.

Array of track vectors:
0 - positive secondary tracks stored at the first point;
1 - negative secondary tracks stored at the first point;
2 - positive primary tracks stored at the first point;
3 - positive primary tracks stored at the first point;
4 - positive secondary tracks stored at the last point;
5 - negative secondary tracks stored at the last point;
6 - positive primary tracks stored at the last point;
7 - positive primary tracks stored at the last point.
