Class Acts::KalmanFitter::Actor¶
-
template<typename source_link_t, typename parameters_t, typename calibrator_t, typename outlier_finder_t>
class Acts::KalmanFitter::Actor¶ Propagator Actor plugin for the KalmanFilter.
The KalmanActor does not rely on the measurements to be sorted along the track.
- tparam source_link_t
is an type fulfilling the
SourceLinkConcept- tparam parameters_t
The type of parameters used for “local” paremeters.
- tparam calibrator_t
The type of calibrator
- tparam outlier_finder_t
Type of the outlier finder class
Public Types
-
using result_type = KalmanFitterResult<source_link_t>¶
