Trk::TrackParticleBase::TrackParticleBase ( )

Constructor 0 standard constructor which sets everything to 0, needed for persistency.

Definition at line 19 of file TrackParticleBase.cxx.

                                          :

◆ TrackParticleBase() [2/4]

Trk::TrackParticleBase::TrackParticleBase	(	const Track *	trk,
		const TrackParticleOrigin	vertexType,
		const VxCandidate *	vxCandidate,
		const TrackSummary *	trkSummary,
		std::vector< const TrackParameters * > &	parameters,
		const TrackParameters *	definingParameter,
		const FitQuality *	fitQuality
	)

Main constructor.

Merged old Constructors 0.5a, 2a and 1a from old (pre 13) TrackParticle constructors & added new info.

I have tried to merge the various TrackParticle constructors (though perhaps we should split this into one which takes RecVertex and one which takes VxCandidate, since they seem to be exclusive)

Parameters

trk	Track used to create this object. Since an ElementLink is used to store the object, setStorableObject(const TrackCollection* trackColl) must be called to set persistency.
vertexType	See TrackParticleOrigin for definitions, but should be set to NoVtx if no VxCandidate pointer is passed.
vxCandidate	Pointer to the VxCandidate used to create this TrackParticleBase.
trkSummary	Summary object of this TrackParticleBase (should be created with TrackSummaryTool). Will be owned by this TrackParticleBase.
parameters	std::vector of TrackParameters which describe this TrackParticleBase. Ownership of these TrackParameters objects passes to TrackParticleBase (so if you copied them from a Track, make sure you didn't just copy the pointers but actually created new objects, for example, by using clone() )
definingParameter	The parameter which defines the charge of this TrackParticleBase and which in derived classes (such as Rec::TrackParticle), could be used to define e.g. the 4-momentum. This will be appended to the vector of parameters passed before, so please make sure that it is NOT already contained in that!
fitQuality	FitQuality which describes this TrackParticleBase. Will be owned by this TrackParticleBase.

Warning: You MUST pass in a valid 'definingParameter' and this 'definingParameter' must NOT be part of the std::vector<const TrackParameters*> passed.

"Various" may seem vague, but it is up to the clients of this class to decide what is needed (Perigee, MuonSpectrometer entrance etc). However, the size of this vector must be at least 1, since ALL TrackParticleBases are required to have ONE defining parameter

◆ m_trackInfo

TrackInfo Trk::TrackParticleBase::m_trackInfo

protected

This is a class which stores the identity of where the track
was created, fitted, which properties the reconstruction had
