Member Function Documentation

void StiKalmanTrackFinder::clear ( void  )

Clear the tracker.

Reset the state of the finder to "no event loaded"

A reset or clear command is used to all components this tracker depends on. This include the hitContainer, the detector container, the hit, track, track node, mc track factories, the track containers, and the seed finder.

Reimplemented from StiTrackFinder.

Definition at line 133 of file StiKalmanTrackFinder.cxx.

References StiHitContainer::clear().

Referenced by StiMaker::Make().

void StiKalmanTrackFinder::findTracks ( )

Find all tracks of the currently loaded event.

Find all tracks associated with the current event.

Algorithm: In a while loop, obtain track seeds from current track seed finder and proceed to extend it through the detector.

Found tracks are added to the track container if no track filter is set or if they satisfy the track filter requirements.

Reimplemented from StiTrackFinder.

Definition at line 153 of file StiKalmanTrackFinder.cxx.

References extendSeeds().

void StiKalmanTrackFinder::reset ( void  )

Reset the tracker.

Reset the state of the finder to "event not tracked"

The track factory, the track container are reset. This method is distinct from the "clear" method which reset the state to "event not loaded".

Reimplemented from StiTrackFinder.

Definition at line 112 of file StiKalmanTrackFinder.cxx.

References BFactory::reset(), and StiDetectorContainer::reset().
