Detailed Description

ConversionTool between the Acts Track EDM and the Trk::Track EDM.

The tool converts entire TrackCollections (vector of Trk::Tracks) into an Acts::TrackContainers and vice versa. The conversion of single Acts::Tracks into a Trk::Track object is also possible. To prepare the refits from Trk::Tracks the tool also converts all meaurement states from a Trk::Track into Acts::SourceLinks.

TrackFitResult_t

using ActsTrk::ITrackConverterTool::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

Member Function Documentation

convertActsToTrkContainer()

virtual std::unique_ptr< TrackCollection > ActsTrk::ITrackConverterTool::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::ITrackConverterTool::convertFitResult ( const EventContext & ctx, TrackFitResult_t & fitResult, const Trk::TrackInfo::TrackFitter fitAuthor ) const

pure virtual

convertTrkToActsContainer()

virtual void ActsTrk::ITrackConverterTool::convertTrkToActsContainer ( const EventContext & ctx, const TrackCollection & trackColl, ActsTrk::MutableTrackContainer & outTrackcoll ) const

pure virtual

Convert the passed Trk::TrackCollection into an Acts Track object and appends the result to the passed.

trkTrackToSourceLinks()

virtual std::vector< Acts::SourceLink > ActsTrk::ITrackConverterTool::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
