Member Typedef Documentation

◆ SurfacePtr_t

using ActsTrk::IActsToTrkConverterTool::SurfacePtr_t = Trk::SurfaceUniquePtrT<const Trk::Surface>

Abrivation of the surface pointer with memory management for free surfaces not associated with a Trk::DetElementBase.

Definition at line 51 of file IActsToTrkConverterTool.h.

◆ TrackFitResult_t

using ActsTrk::IActsToTrkConverterTool::TrackFitResult_t = Acts::Result<ActsTrk::MutableTrackContainer::TrackProxy, std::error_code>

Convert the Acts fit result into a Trk::Track object, if the fit was successful.

Otherwise, a nullptr is returned.

Parameters

ctx	EventContext to construct the Geometry & calibration context inside
fitResult	Outcome from the Acts fitter
fitAuthor	Author flag to be put into the Trk::Track meta data
slType	Source link type steering how the uncalibrated Acts::SourceLinks are turned into Trk::MeasurementBase objects

◆ actsSurfaceToTrkSurface()

virtual SurfacePtr_t ActsTrk::IActsToTrkConverterTool::actsSurfaceToTrkSurface	(	const EventContext &	ctx,
		const Acts::Surface &	actsSurface ) const

pure virtual

Translates the parsed Acts surface into a Trk::Surface via associated detector element.

For the ID measurements a direct link is provided and for the muon measurements the look-up is performed via the associated Identifier and the detector manager. Other surfaces trigger the creation of new free Trk surfaces

Parameters

ctx	The current event context
actsSurface	Refrence to the acts surface to translate

◆ actsTrackParametersToTrkParameters()

virtual std::unique_ptr< Trk::TrackParameters > ActsTrk::IActsToTrkConverterTool::actsTrackParametersToTrkParameters	(	const EventContext &	ctx,
		const Acts::BoundTrackParameters &	actsParameter,
		const Acts::GeometryContext &	gctx ) const

pure virtual

Translates the bounded Acts track parameters to Trk parameters.

The bound parameter surface must be translatble by the tool

Parameters

ctx	EventContext
actsParameter	Refrence to the bounded parameters to translate
gctx	Geometry context to align the associated surface in global space

◆ convertActsToTrkContainer()

virtual std::unique_ptr< TrackCollection > ActsTrk::IActsToTrkConverterTool::convertActsToTrkContainer	(	const EventContext &	ctx,
		const ActsTrk::TrackContainer &	trackCont ) const

pure virtual

Converts the Acts track container to a Trk::Track collection.

Parameters

ctx	EventContext to access the current conditions (alignment, calibration, etc.)
trackCont	Reference to the track container for legacy converstion

◆ convertFitResult()

virtual std::unique_ptr< Trk::Track > ActsTrk::IActsToTrkConverterTool::convertFitResult	(	const EventContext &	ctx,
		TrackFitResult_t &	fitResult,
		const Trk::TrackInfo::TrackFitter	fitAuthor,
		const detail::SourceLinkType	slType ) const

pure virtual

◆ DeclareInterfaceID()

ActsTrk::IActsToTrkConverterTool::DeclareInterfaceID	(	IActsToTrkConverterTool	,
		1	,
		0	)

◆ toSourceLinks() [1/2]

virtual void ActsTrk::IActsToTrkConverterTool::toSourceLinks	(	const std::vector< const Trk::MeasurementBase * > &	measSet,
		std::vector< Acts::SourceLink > &	links ) const

pure virtual

Converts a vector of Trk measurement states into a vector of Acts source links and appends the result to the exisiting set of source links.

Parameters

measSet	Reference to the measurement set to transform
link	Target vector to which the new source links are appended

◆ toSourceLinks() [2/2]

virtual void ActsTrk::IActsToTrkConverterTool::toSourceLinks	(	const std::vector< const Trk::PrepRawData * > &	prdSet,
		std::vector< Acts::SourceLink > &	links ) const

pure virtual

Converts a vector of Trk::PrepRawData states into a vector of Acts source links and appends the result to the exisiting set of source links.

Parameters

measSet	Reference to the measurement set to transform
link	Target vector to which the new source links are appended

◆ trkSurfaceToActsSurface()

virtual std::shared_ptr< const Acts::Surface > ActsTrk::IActsToTrkConverterTool::trkSurfaceToActsSurface ( const Trk::Surface & atlasSurface ) const

pure virtual

Translate the parsed Trk surface into an Acts surface.

The detector element identifier of the surface needs to be filled into the internal tool's look-up map. Otherwise an exception is thrown.

Parameters

atlasSurface Refrence to the Trk surface to translate

◆ trkTrackCollectionToActsTrackContainer()

virtual void ActsTrk::IActsToTrkConverterTool::trkTrackCollectionToActsTrackContainer	(	ActsTrk::MutableTrackContainer &	tc,
		const TrackCollection &	trackColl,
		const Acts::GeometryContext &	gctx ) const

pure virtual

◆ trkTrackParametersToActsParameters()

virtual const Acts::BoundTrackParameters ActsTrk::IActsToTrkConverterTool::trkTrackParametersToActsParameters	(	const Trk::TrackParameters &	atlasParameter,
		const Acts::GeometryContext &	gctx,
		Trk::ParticleHypothesis	hypothesis = Trk::pion ) const

pure virtual

Translates the Trk track parameters into bound Acts track parameters with a particle hypothesis.

Parameters

atlasParameter	The Trk parameters to translate.
gcts	Geometry context needed for special treatment of the annulus bounds
hypothesis	Track hypothesis to use

◆ trkTrackToSourceLinks()

virtual std::vector< Acts::SourceLink > ActsTrk::IActsToTrkConverterTool::trkTrackToSourceLinks ( const Trk::Track & track ) const

pure virtual

Converts the Trk measurement track states into a vector of Acts::Source links.

The source links don't take ownership over the measurement states.

Parameters

track Reference to the track to convert
