Class making kinematic fit of the particle inside the KinematicTree. The daughter states of the tree get automathically refitted according to the changes done to mother state. Mechanism is split in 2 parts: ParentParticleFitter to fit the mother particle and ChildUpdator to update the states of daughter particles. Child updator is currently not implemented. Fitter is designed to use any user provided algorithm for state refit.

) | const |
Method applying the constraint to the TOP particle inside the Kinematic Tree. Tree containing the refitted state is returned. The initial state of the particle and constraint applyed are stored in particle's corresponding data memebers In case of failure, an empty vector is returned.

RefCountedKinematicTree KinematicParticleFitter::fit | ( | KinematicConstraint * | cs, |
RefCountedKinematicTree | tree | ||
) | const |
Method refitting a top particle of the single tree. for backup compatibility and constraints not allowing multiple track refits. In case of failure, an invalid tree is returned.
