◆ collect()

template<typename ... types>

static void collect ( const types & ... )

inlinestaticinherited

static method used by the observed object to prepare the observer it is called by the boolean filter operator.

◆ collectMCParticles()

template<class hitType>

static void collectMCParticles	(	const hitType &	aHit,
		std::vector< const MCParticle * > &	collectedParticles )

inlinestatic

collects all mcParticles connected to given hit.

does only work, if hit has direct relations PXD/SVDCluster which have relations to MCParticle.

first parameter is a hit (e.g. spacePoint) which is related to MCParticles. second parameter is the vector for collecting the PDGcodes found.
