FindFirstHits() [1/2]

SQHitVector * UtilSQHit::FindFirstHits	(	const SQHitVector *	vec_in,
		const int	det_id,
		const bool	in_time = false
	)

FindFirstHits() [2/2]

SQHitVector * UtilSQHit::FindFirstHits	(	const SQHitVector *	vec_in,
		const std::string	det_name,

Extract a set of first hits that are of the given detector (det_name), where "first" means the earliest (i.e. largest TDC time) hit per element.

FindHits() [2/2]

SQHitVector * UtilSQHit::FindHits	(	const SQHitVector *	vec_in,
		const std::string	det_name,
		const bool	in_time = false
	)

Extract a set of hits that are of the given detector (det_name).

The SQHitVector object returned has to be deleted outside this function. The recommended way is to use "shared_ptr", which auto-deletes the object.

shared_ptr<SQHitVector> hv_h1t(UtilSQHit::FindHits(hit_vec, "H1T"));
cout << "N = " << hv_h1t->size() << endl;

Here is the caller graph for this function:

FindHitsFast() [1/2]

std::vector< SQHit * > * UtilSQHit::FindHitsFast	(	const SQEvent *	evt,
		const SQHitVector *	hit_vec,
		const int	det_id
	)

Fast-extract a set of hits that are of the given detector (det_id).

Useful for speed when many SubsysReco modules are registered and accessing the hit vector repeatedly. The returned variable is vector<SQHit*> (not SQHitVector), which can be used as follows for example:

auto vec = UtilSQHit::FindHitsFast(evt, hit_vec, det_id);
for (auto it = vec->begin(); it != vec->end(); it++) {
  int    ele_id = (*it)->get_element_id();
  double time   = (*it)->get_tdc_time  ();
}

Caller must not delete the vector nor the SQHit objects.

This function has an internal static variable that holds one hit vector per detector. The variable is filled only on the 1st call per event, and used by all SubsysReco modules. The reason of using vector<SQHit*> is to avoid multiple creations+deletions of SQHitVector.
