Constructor & Destructor Documentation

TrackParticle() [1/4]

Rec::TrackParticle::TrackParticle

(

)

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

Definition at line 35 of file TrackParticle.cxx.

TrackParticle() [2/4]

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

'Beautiful' TrackParticle Constructor.

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.
trkPrtOrigin	See TrackParticleOrigin for definitions, but should be set to NoVtx if no Trk::VxCandidate pointer is passed.
vxCandidate	Pointer to the Trk::VxCandidate used to create this TrackParticle.
trkSummary	Summary object of this TrackParticle (should be created with Trk::TrackSummaryTool). Will be owned by this TrackParticle.
parameters	std::vector of Trk::TrackParameters which describe this Trk::TrackParticle. Ownership of these Trk::TrackParameters objects passes to TrackParticle (so if you copied them from a Trk::Track, make sure you didn't just copy the pointers but actually created new objects, for example, by using clone() )
definingParameter	The Trk::TrackParameters which defines the charge and 4-momentum of this TrackParticle. This will be appended to the vector of parameters passed before, so please make sure that it is NOT already contained in that!
fitQuality	Trk::FitQuality which describes this Trk::TrackParticle. Will be owned by this TrackParticle.

Warning

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

TrackParticle() [3/4]

Rec::TrackParticle::TrackParticle	(	const ElementLink< TrackCollection > &	trackLink,

		std::unique_ptr< Trk::FitQuality >	fitQuality,
		const Trk::TrackInfo &	info,
		const P4PxPyPzE &	mom
	)

Alternate constructor, to be used by TP converters.

Passes in ElementLinks rather than pointers, and does not dereference those links.

Parameters

trackLink	Link to track used to create this object.
trkPrtOrigin	See TrackParticleOrigin for definitions, but should be set to NoVtx if no Trk::VxCandidate pointer is passed.
vxCandidate	Link to the Trk::VxCandidate used to create this TrackParticle.
trkSummary	Summary object of this TrackParticle (should be created with Trk::TrackSummaryTool).
parameters	std::vector of Trk::TrackParameters which describe this Trk::TrackParticle. Ownership of these Trk::TrackParameters objects passes to TrackParticle (so if you copied them from a Trk::Track, make sure you didn't just copy the pointers but actually created new objects, for example, by using clone()). In contrast to the previous constructor, this vector must constain the defining parameters.
fitQuality	Trk::FitQuality which describes this TrackParticle.
info	TrackInfo for this track.
mom	Four-momentum for this particle.

Accessor method for Perigee.

Warning

A TrackParticle is REQUIRED to have a Trk::Perigee and so this pointer should never be zero, however internally it is cached using a dynamic_cast and so in principle this cast could fail if the object is constructed improperly. There is an assert to test this in debug.

This method should properly return the Perigee by reference, but it is a bit late to make interface changes this close to 13.0.0
