Member Enumeration Documentation

◆ RefereeStatusBit

enum RefereeStatusBit

Status information that can be set to indicate several properties of the SpacePointTrackCand.

NOTE: Some properties are at the moment stored in other members of the SpacePointTrackCand, can be moved here, if memory usage is an issue. NOTE: If you add something here, it should also be added in the 'getRefereeStatusString' method!

Enumerator
c_checkedByReferee	bit 0: SPTC has been checked by a Referee (all possible tests).
c_checkedClean	bit 1: SPTC shows no 'problematic' behaviour.
c_hitsOnSameSensor	bit 2: SPTC has two (or more) SpacePoints on same sensor.
c_hitsLowDistance	bit 3: SPTC has two (or more) SpacePoints that are not far enough apart. NOTE: distance is judged by referee (and also set there).
c_removedHits	bit 4: SpacePoints were removed from this SPTC.
c_checkedTrueHits	bit 5: All SpacePoints of the SPTC have a relation to at least one TrueHit.
c_checkedSameSensors	bit 6: It has been checked, if two consecutive SpacePoints are on the same sensor for this SPTC.
c_checkedMinDistance	bit 7: It has been checked if two consecutive SpacePoints are far enough apart.
c_curlingTrack	bit 8: SPTC is curling (resp. is part of a curling SPTC).
c_omittedClusters	bit 9: Not all Clusters of the genfit::TrackCand have been used to create this SPTC.
c_singleClustersSPs	bit 10: SPTC contains single Cluster SpacePoints.
c_isActive	bit 11: SPTC is active (i.e. if false, some module rejected it for further use.
c_isReserved	bit 12: SPTC is reserved (i.e. should not be altered and should be treated with high priority).
c_hasFittedRecoTrack	bit 13: SPTC is related to a RecoTrack which has a successful fit. NOTE: this check is performed on the original SPTC, if the current one is a copy of that the relation may be lost
c_initialState	This is the initialState, which will always be set in the beginning and at reset.

Constructor & Destructor Documentation

◆ SpacePointTrackCand() [1/2]

SpacePointTrackCand ( )

default

Empty constructor with default values, including it to be active.

Sets pdg code to zero to make it possible to determine, whether a particle hyptohesis has been asigned to the track candidate or not.MCTrackID is initialized to -1.
Each SPTC is created in c_isActive-state and has to be deactivated manually, if need be.

◆ SpacePointTrackCand() [2/2]

SpacePointTrackCand	(	const std::vector< const Belle2::SpacePoint * > &	spacePoints,
		int	pdgCode = `0`,
		double	charge = `0`,
		int	mcTrackID = `-1`
	)

explicit

Constructor from a vector<SpacePoint*> and some additional information.

Parameters

spacePoints	list of pointers to the SpacePoint for this track candidate
pdgCode	Mass hypothesis to be used.
charge	Charge hypthesis for the tracked particle.
mcTrackID	??? sortingParameters are generated from the order of the SpacePoints! Each SPTC is created in c_isActive-state and has to be deactivated manually, if need be.

< default sorting parameters

inlineinherited

Copies all relations of sourceObj (pointing from or to sourceObj) to this object (including weights).

◆ getInfoHTML()

virtual std::string getInfoHTML ( ) const

inlinevirtualinherited

Return a short summary of this object's contents in HTML format.

Reimplement this in your own class to provide useful output for display or debugging purposes. For example, you might do something like:

std::stringstream out;
out << "<b>PDG</b>: " << m_pdg << "<br>";
out << "<b>Covariance Matrix</b>: " << HTML::getString(getCovariance5()) << "<br>";
return out.str();

See also: Particle::getInfoHTML() for a more complex example.; HTML for some utility functions.; Use getInfo() to get a raw text version of this output.

bool hasRemovedHits ( ) const

inline

Check if a SpacePointTrackCand has removed hits (i.e.

at some point it contained more hits than it does when this function is called, removal of hits e.g. by a referee module)

Definition at line 239 of file SpacePointTrackCand.h.

◆ isCurling()

bool isCurling ( ) const

inline

get if the TrackCand is curling.

WARNING: does not check if this has actually been assigned!

Definition at line 250 of file SpacePointTrackCand.h.

◆ isPartOfCurlingTrack()

bool isPartOfCurlingTrack ( ) const

inline

check if the TrackCand is part of a curling TrackCand.

NOTE: returns false if curling has not been checked

Definition at line 256 of file SpacePointTrackCand.h.

◆ operator<()

bool operator< ( const SpacePointTrackCand & rhs ) const

inline

Overloading the less operator to compare SPTCs based on their quality index.

This is used in in SPTCSelectorXBestPerFamily for instance.

Definition at line 349 of file SpacePointTrackCand.h.

◆ print()

void print	(	int	debuglevel = `25`,
		const Option_t *	option = `""`
	)		const

print the Track Candidate in its "full beauty".

NOTE: prints some parts to stdout, since for printing the state seed the print method form TVectorD is invoked!

Definition at line 156 of file SpacePointTrackCand.cc.

◆ setFlightDirection()

void setFlightDirection ( bool direction )

inline

set the direction of flight (true is outgoing, false is ingoing).

Initialized to true by default!

Definition at line 324 of file SpacePointTrackCand.h.

◆ setQualityIndicator()

void setQualityIndicator ( const double newIndicator )

inline

sets the new status of the estimated quality of this track candidate.

valid are values in range [0;1] if value < 0, the track candidate is invalid and one should not use it anymore. 0.5 is the standard value if not been set otherwise

Definition at line 310 of file SpacePointTrackCand.h.

Member Data Documentation

◆ m_flightDirection

bool m_flightDirection = true

protected

direction of flight.

true is outgoing, false is ingoing

Definition at line 396 of file SpacePointTrackCand.h.

◆ m_iTrackStub

int m_iTrackStub = -1

protected

Index of TrackStub in a curling Track Candidate.

If the TrackCandidate is not curling this value is set to 0.
If it is not yet checked if the TrackCand is curling it is set to -1.
If it is a curling TrackCand the counter starts at 1, indicating that this is the first outgoing part of the TrackCand. COULDDO: implement such a feature via something like a linked list (would be much nicer, but for the moment this little workaround works)

Definition at line 405 of file SpacePointTrackCand.h.

◆ m_qualityIndicator

double m_qualityIndicator = 0.5

protected

An estimation for the quality of the track.

Normally defined between 0-1 to describe the propability that this track is real(istic). The quality of the track has to be determined by another function or module.

Definition at line 418 of file SpacePointTrackCand.h.
