class TrackSelector
#include <Acts/TrackFinding/TrackSelector.hpp>

Class which performs filtering of tracks.

It accepts an input and an output track container and uses the built-in copy facility to copy tracks into the output container.

Public Functions

inline TrackSelector(const Config &config)

Constructor from a config object.

Parameters

config – is the configuration object

inline const Config &config() const

Get readonly access to the config parameters.

Returns

the config object

template<typename track_proxy_t>
bool isValidTrack(const track_proxy_t &track) const

Helper function to check if a track is valid.

Template Parameters

track_proxy_t – is the type of the track proxy

Parameters

track – is the track proxy

Returns

true if the track is valid

template<typename input_tracks_t, typename output_tracks_t>
void selectTracks(const input_tracks_t &inputTracks, output_tracks_t &outputTracks) const

Select tracks from an input container and copy them into an output container.

Template Parameters

  • input_tracks_t – is the type of the input track container

  • output_tracks_t – is the type of the output track container

Parameters

  • inputTracks – is the input track container

  • outputTracks – is the output track container
