Member Function Documentation

getNumberOfCorrectHits()

unsigned int getNumberOfCorrectHits ( const CDCTrack *  ptrCDCTrack ) const

private

Get number of hits in track that are correctly matched.

operator()()

bool operator()	(	const CDCTrack *	ptrCDCTrack1,
		const CDCTrack *	ptrCDCTrack2
	)		const

Compare both CDC tracks to get the better matched one.

Functor definition of comparison function for findBestMatchedTrack.

Returns true if track1 has a lower loop number at the first hit than track1. If both tracks have the same loop number, return true if track1 has larger number of matched hits.

  // If it is equal, use track with the larger number of correct hits.
