Member Function Documentation

getCovariance()

virtual double Trk::AlignmentDeviation::getCovariance ( int ipar, int jpar ) const

pure virtual

The error matrix on the free parameters.

Track fitters should use this to compute a constraint on the free parameters.

Implemented in MuonAlign::AlignmentRotationDeviation, and MuonAlign::AlignmentTranslationDeviation.

getHashOfHits()

std::size_t Trk::AlignmentDeviation::getHashOfHits ( ) const

inline

Return hash built out of associated hits for fast comparison if deviations have same content.

Definition at line 88 of file AlignmentDeviation.h.

{ return m_hitshash; }

getListOfHits()

const std::vector< const Trk::RIO_OnTrack * > & Trk::AlignmentDeviation::getListOfHits ( ) const

inline

Return the list of hits the transform should be applied to.

Definition at line 86 of file AlignmentDeviation.h.

{ return m_hits; }

getTransform()

virtual Amg::Transform3D Trk::AlignmentDeviation::getTransform ( const std::vector< double > & parameters ) const

pure virtual

Return a Transform in the global coordinate system, given a list of parameters.

Implemented in MuonAlign::AlignmentRotationDeviation, and MuonAlign::AlignmentTranslationDeviation.

hasValidHashOfHits()

bool Trk::AlignmentDeviation::hasValidHashOfHits ( ) const

inline

Return if the hash created form associated hits is set.

Definition at line 95 of file AlignmentDeviation.h.

{ return m_hitshashdone; }

nPar()

virtual int Trk::AlignmentDeviation::nPar ( ) const

pure virtual

The number of free parameters.

Implemented in MuonAlign::AlignmentRotationDeviation, and MuonAlign::AlignmentTranslationDeviation.

print()

virtual void Trk::AlignmentDeviation::print ( std::ostream & out ) const

pure virtual

Verbose.

Implemented in MuonAlign::AlignmentRotationDeviation, and MuonAlign::AlignmentTranslationDeviation.

setHashOfHits()

void Trk::AlignmentDeviation::setHashOfHits ( std::size_t hash )

inline

Set hash built out of associated hits - cannot be calculated in constructor because of dependencies.

Definition at line 90 of file AlignmentDeviation.h.

                                                                {
        m_hitshash = hash;
        m_hitshashdone = true;
    }
