create()

CDCFacetSegment create ( const CDCRLWireHitSegment &  rlWireHitSegment )

getAliasScore()

double getAliasScore ( ) const

inlineinherited

Getter for the flag that this segment may have an aliased version.

Definition at line 90 of file CDCSegment.h.

      {
        return m_aliasScore;
      }

getISuperLayer()

ISuperLayer getISuperLayer ( ) const

inlineinherited

Returns the common super layer id of all stored tracking hits.

This checks if all items are located in the same superlayer and returns the superlayer id of the later. Returns ISuperLayerUtil::c_Invalid, if the superlayer is not shared among the hits.

Definition at line 57 of file CDCSegment.h.

      {
        return ISuperLayerUtil::getFrom(this->front());
      }

getStereoKind()

EStereoKind getStereoKind ( ) const

inlineinherited

Returns the common stereo type of all hits.

This checks if all tracking hits are located in the same superlayer and
returns the stereo type of the later. Returns EStereoKind::c_Invalid if the superlayer
is not shared among the tracking hits.

Definition at line 39 of file CDCSegment.h.

      {
        return ISuperLayerUtil::getStereoKind(getISuperLayer());
      }

getTrajectory2D()

CDCTrajectory2D & getTrajectory2D ( ) const

inlineinherited

Getter for the two dimensional trajectory fitted to the segment.

Definition at line 69 of file CDCSegment.h.

      {
        return m_trajectory2D;
      }

isAxial()

bool isAxial ( ) const

inlineinherited

Indicator if the underlying wires are axial.

Definition at line 45 of file CDCSegment.h.

      {
        return getStereoKind() == EStereoKind::c_Axial;
      }

items()

const std::vector< CDCFacet > & items ( ) const

inlineinherited

Legacy accessor for the items of the segments, still used in some corners.

Definition at line 63 of file CDCSegment.h.

      {
        return *this;
      }

setAliasScore()

void setAliasScore ( double  aliasScore )

inlineinherited

Setter for the flag that this segment may have an aliased version.

Definition at line 96 of file CDCSegment.h.

      {
        m_aliasScore = aliasScore;
      }

setTrajectory2D()

void setTrajectory2D ( const CDCTrajectory2D &  trajectory2D ) const

inlineinherited

Setter for the two dimensional trajectory fitted to the segment.

Definition at line 75 of file CDCSegment.h.

      {
        m_trajectory2D = trajectory2D;
      }

sortByArcLength2D()

void sortByArcLength2D ( )

inlineinherited

Sort the recoHits according to their perpS information.

Definition at line 81 of file CDCSegment.h.

      {
        // cppcheck-suppress constParameter
        std::stable_sort(this->begin(), this->end(), [](const T & recoHit, const T & otherRecoHit) {
          return recoHit.getArcLength2D() < otherRecoHit.getArcLength2D();
        });
      }
