void VertexConstraint::add2ndDerivativesToMatrix (  int  idim, double *  M, double  lambda )  const [virtual]

Adds second order derivatives to global covariance matrix M. Implements BaseConstraint. Definition at line 74 of file VertexConstraint.C.

void VertexConstraint::getDerivatives (  int  idim, double  der[] )  const [virtual]

Get first order derivatives. Call this with a predefined array "der" with the necessary number of entries! Implements BaseConstraint. Definition at line 51 of file VertexConstraint.C. References factor, TrackFitObject::getGlobalParNum(), VertexFitObject::getGlobalParNum(), TrackFitObject::getNPar(), VertexFitObject::getNPar(), TrackFitObject::getVertexDerivative(), VertexFitObject::getVertexDerivative(), TrackFitObject::isParamFixed(), VertexFitObject::isParamFixed(), ivertex, track, and vertex.

virtual int VertexConstraint::getGlobalNum (   )  const [inline, virtual]

Accesses position of constraint in global constraint list. Implements BaseConstraint. Definition at line 56 of file VertexConstraint.h. References globalNum.

double VertexConstraint::getValue (   )  const [virtual]

Returns the value of the constraint. Implements BaseConstraint. Definition at line 36 of file VertexConstraint.C. References factor, TrackFitObject::getVertex(), VertexFitObject::getVertex(), ivertex, track, and vertex.

virtual void VertexConstraint::setGlobalNum (  int  iglobal  )  [inline, virtual]

Sets position of constraint in global constraint list. Implements BaseConstraint. Definition at line 58 of file VertexConstraint.h. References globalNum.
