Function Documentation

getUniqueClusters()

std::vector<const ClusterType*> Belle2::AnalyzingAlgorithmHelper::getUniqueClusters	(	std::vector< const ClusterType * > &	firstTC,
		std::vector< const ClusterType * > &	secondTC
	)

helper function to retrieve the number of unique Clusters of first tc given, compared with second tc

WARNING: unique clusters of secondTC are ignored on purpose! if you want both, just re-run the function with switched sides for first and second TC
