FindDetectorHitsOfTrack() [1/2]

SQHitVector * UtilTrack::FindDetectorHitsOfTrack	(	const SQHitVector *	vec_in,
		const int	id_trk,
		const char *	det_name
	)

Find track-associated hits whose detector name starts with 'det_name'.

FindDetectorHitsOfTrack() [2/2]

SQHitVector * UtilTrack::FindDetectorHitsOfTrack	(	const SQHitVector *	vec_in,
		const int	id_trk,
		const std::string	det_name
	)

Find track-associated hits whose detector name starts with 'det_name'.

Examples:

shared_ptr<SQHitVector> hit_vec_trk_d0(UtilTrack::FindDetectorHitsOfTrack(hit_vec, id_trk, "D0"));

You can use "FindHodoHitsOfTrack()" to more-conveniently find all hodoscope hits.

FindHitsOfTrack()

SQHitVector * UtilTrack::FindHitsOfTrack	(	const SQHitVector *	vec_in,
		const int	id_trk
	)

Find all hits associated with the given track.

It is recommended to receive the returned pointer by "shared_ptr".

Find all hodoscope hits hits associated with the given track.

Example:

shared_ptr<SQHitVector> hit_vec_trk(UtilTrack::FindHodoHitsOfTrack(hit_vec, id_trk));

FindTrackByID()

SQTrack * UtilTrack::FindTrackByID	(	const SQTrackVector *	vec,
		const int	id_trk,
		const bool	do_assert = false
	)

Find a track by track ID in the given track list.

This function returns a SQTrack pointer if successful. Otherwise it returns '0' by default, or aborts when 'do_assert' = true.
