Nested Relationships

This class is a nested type of Template Class KalmanFitter.

Class Documentation

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.

Template Parameters

  • source_link_t: is an type fulfilling the SourceLinkConcept

  • parameters_t: The type of parameters used for “local” paremeters.

  • calibrator_t: The type of calibrator

  • outlier_finder_t: Type of the outlier finder class

Public Types

using result_type = KalmanFitterResult<source_link_t>

Broadcast the result_type.
