Detailed Description

Interface for the conversion tool to translate the surface and track parameter objects between the Acts & the ATLAS Trk realm.

Surfaces associated with readout planes are taken from the corresponding tracking geometries Acts portal surfaces and other free surfaces are translated as free trk surfaces. Analogously, free Trk surfaces are translated to a free Acts surface.

Member Function Documentation

convertSurfaceToActs()

virtual std::shared_ptr< const Acts::Surface > ActsTrk::IGeometryRealmConvTool::convertSurfaceToActs ( 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

convertSurfaceToTrk()

virtual SurfacePtr_t ActsTrk::IGeometryRealmConvTool::convertSurfaceToTrk ( 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

convertTrackParametersToActs()

virtual Acts::BoundTrackParameters ActsTrk::IGeometryRealmConvTool::convertTrackParametersToActs ( const EventContext & ctx, const Trk::TrackParameters & atlasParameter, 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

convertTrackParametersToTrk()

virtual std::unique_ptr< Trk::TrackParameters > ActsTrk::IGeometryRealmConvTool::convertTrackParametersToTrk ( const EventContext & ctx, const Acts::BoundTrackParameters & actsParameters ) 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
