References ParticleConstraint::ConstFitObjectIterator, ParticleConstraint::fitobjects, ParticleFitObject::getDPx(), ParticleConstraint::getGlobalNum(), ParticleFitObject::getGlobalParNum(), ParticleFitObject::getNPar(), and ParticleFitObject::isParamFixed().

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

Adds second order derivatives, multiplied by lambda, to global covariance matrix M. Reimplemented from ParticleConstraint. Definition at line 95 of file PConstraint.C.

double PConstraint::getValue (   )  const [virtual]

Returns the value of the constraint. Implements ParticleConstraint. Definition at line 36 of file PConstraint.C. References efact, ParticleConstraint::fitobjects, pxfact, pyfact, pzfact, and value.

void PConstraint::invalidateCache (   )  const [virtual]

Invalidates any cached values for the next event. Reimplemented from ParticleConstraint. Definition at line 145 of file PConstraint.C. References cachevalid.

void PConstraint::updateCache (   )  const [protected]

Definition at line 149 of file PConstraint.C. References cachevalid, ParticleConstraint::fitobjects, and nparams. Referenced by addToGlobalDerMatrix().
