Detailed Description

This class is the base of all detector elements that are usable by ACTS.

All experiment-specific detector element classes are expected to inherit from it.

Deprecated

: This class is deprecated in favour of SurfacePlacementBase

Remarks

It is possible toe replace this base class by defining a ACTS_DETECTOR_ELEMENT_BASE_REPLACEMENT pre-processor replacement. If found, SurfacePlacementBase.hpp will instead include that file.

Member Function Documentation

isSensitive()

bool Acts::DetectorElementBase::isSensitive ( ) const

overridevirtual

Returns whether the detector element corresponds to a sensitive surface on which measurements are expressed.

Implements Acts::SurfacePlacementBase.

localToGlobalTransform()

const Transform3 & Acts::DetectorElementBase::localToGlobalTransform ( const GeometryContext & gctx ) const

overridevirtual

Return the transform for the Element proxy mechanism.

Parameters

gctx	The current geometry context object, e.g. alignment

Returns

reference to the transform to switch from the element's coordinates to the experiment's global coordinate system

Implements Acts::SurfacePlacementBase.

thickness()

virtual double Acts::DetectorElementBase::thickness ( ) const

pure virtual

Returns the thickness of the module.

Returns

double that indicates the thickness of the module

transform()

virtual const Transform3 & Acts::DetectorElementBase::transform ( const GeometryContext & gctx ) const

virtual

Return the transform for the Element proxy mechanism.

Parameters

gctx	The current geometry context object, e.g. alignment

Returns

reference to the transform of this detector element
