Member Function Documentation

float KinematicParticle::chiSquared ( ) const

virtual

Access metods for chi2 and number of degrees of freedom

Definition at line 27 of file KinematicParticle.cc.

References chi2.

{return chi2;}

KinematicTree * KinematicParticle::correspondingTree ( ) const

virtual

Returns the pointer to the kinematic tree (if any) current particle belongs to 0 pointer returned in case not any tree is built yet

Definition at line 24 of file KinematicParticle.cc.

References tree.

{return tree;}

KinematicState KinematicParticle::currentState ( ) const

virtual

Access to the last calculated kinematic state

Definition at line 15 of file KinematicParticle.cc.

References cState.

Referenced by refittedTransientTrack().

{return cState;}

float KinematicParticle::degreesOfFreedom ( ) const

virtual

Definition at line 30 of file KinematicParticle.cc.

References ndf.

{return ndf;}

KinematicState KinematicParticle::initialState ( ) const

virtual

Access to the kinematic state with which particle was first created

Definition at line 12 of file KinematicParticle.cc.

References initState.

Referenced by VirtualKinematicParticle::operator==(), and TransientTrackKinematicParticle::operator==().

{return initState;}

KinematicConstraint * KinematicParticle::lastConstraint ( ) const

virtual

Returns last constraint aplied to this particle.

Definition at line 18 of file KinematicParticle.cc.

References lConstraint.

{return lConstraint;}

const MagneticField* KinematicParticle::magneticField ( ) const

inline

Definition at line 122 of file KinematicParticle.h.

References theField.

{return theField;}

virtual bool KinematicParticle::operator!= ( const KinematicParticle &  other ) const

pure virtual

Implemented in TransientTrackKinematicParticle, and VirtualKinematicParticle.

bool KinematicParticle::operator< ( const KinematicParticle &  other ) const

virtual

Comparison by adress operator Has NO physical meaning To be used inside graph only

Definition at line 5 of file KinematicParticle.cc.

{
 bool res = false;
 if(this < &other) res=true;
 return res;
}

virtual bool KinematicParticle::operator== ( const KinematicParticle &  other ) const

pure virtual

Comparison by contents operators Returns TRUE if initial PhysicsObjects match(if they exist). If not, compares the initial KinematicStates Retunes true if they match. Should be implemented by user

Implemented in TransientTrackKinematicParticle, and VirtualKinematicParticle.

virtual bool KinematicParticle::operator== ( const ReferenceCountingPointer< KinematicParticle > &  other ) const

pure virtual

Implemented in TransientTrackKinematicParticle, and VirtualKinematicParticle.

virtual RefCountedLinearizedTrackState KinematicParticle::particleLinearizedTrackState ( const GlobalPoint &  point ) const

pure virtual

Method returning LinearizedTrackState of the particle needed for Kalman flter vertex fit. Should be implemented by user. For track(helix)-like objects one can use the ParticleLinearizedTrackStateFactory class.

Implemented in TransientTrackKinematicParticle, and VirtualKinematicParticle.

ReferenceCountingPointer< KinematicParticle > KinematicParticle::previousParticle ( ) const

virtual

Returns the state of Kinematic Particle before last constraint was aplied

pure virtual

Method producing new particle out of the current one and RefittedState obtained from kinematic fitting. To be used by Fitter classes only. Method should be implemented by used for every specific type of KinematicParticle

Implemented in TransientTrackKinematicParticle, and VirtualKinematicParticle.
