Template Class KalmanFitter::Actor

Nested Relationships

This class is a nested type of Template Class KalmanFitter.

Class Documentation

template<typename source_link_t, typename parameters_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.

Public Types

using result_type = KalmanFitterResult<source_link_t>

Broadcast the result_type.

using TrackStateType = TrackState<source_link_t, parameters_t>

Public Functions

Actor(updater_t pUpdater = updater_t(), smoother_t pSmoother = smoother_t(), outlier_finder_t pOutlierFinder = outlier_finder_t(), calibrator_t pCalibrator = calibrator_t())

Explicit constructor with updater and calibrator.
