Public Member Functions
	CDCMCMap ()=default
	Default constructor, needs to be public for initialization in CDCMCManager.
CDCMCMap &	operator= (const CDCMCMap &)=delete
	Delete the assignement operator in order to avoid accidental copies.
	CDCMCMap (CDCMCMap &)=delete
	For the same reason, also delete copy constructor.
void	clear ()
	Clear all information from the former event.
void	fill ()
	Fill the Monte Carlo information retrieved from the DataStore into the local multimaps.
MayBePtr< const CDCSimHit >	getSimHit (const CDCHit *hit) const
	Seeks the CDCSimHit related to the CDCHit.
MayBePtr< const CDCHit >	getHit (const CDCSimHit *simHit) const
	Seeks the CDCHit related to the CDCSimHit - nullptr if no CDCHit is related.
bool	isBackground (const CDCSimHit *simHit) const
	Indicates if the CDCSimHit is considered background.
bool	isBackground (const CDCHit *hit) const
	Indicates if the CDCSimHit is considered background.
MayBePtr< const MCParticle >	getMCParticle (const CDCHit *hit) const
	Seeks the MCParticle related to the CDCHit. More...
MayBePtr< const MCParticle >	getMCParticle (const CDCSimHit *simHit) const
	Seeks the MCParticle related to the CDCSimHit. More...
auto	getSimHits (const MCParticle *mcParticle) const
	Getter for the range MCParticle to CDCSimHits relations which come from the given MCParticle.
auto	getHits (const MCParticle *mcParticle) const
	Getter for the range MCParticle to CDCHits relations which come from the given MCParticle.
bool	isReassignedSecondary (const CDCSimHit *ptrSimHit) const
	Indicates if the CDCSimHit has been reassigned to a primary MCParticle.
bool	isReassignedSecondary (const CDCHit *ptrHit) const
	Indicates if the CDCHit has been reassigned to a primary MCParticle.
const std::set< const CDCHit * > &	getReassignedSecondaryHits () const
	Getter for all reassigned secondary CDCHits.
const std::set< const CDCSimHit * > &	getReassignedSecondarySimHits () const
	Getter for all reassigned secondary CDCSimHits.
const std::multimap< const CDCHit *, const CDCSimHit * > &	getSimHitsByHit () const
	Getter for the CDCHit -> CDCSimHit relations.
const std::multimap< const MCParticle *, const CDCHit * > &	getHitsByMCParticle () const
	Getter for the MCParticle -> CDCHit relations.
const std::multimap< const MCParticle *, const CDCSimHit * > &	getSimHitsByMCParticle () const
	Getter for the MCParticle -> CDCSimHit relations.

Private Member Functions
void	fillSimHitByHitMap ()
	Retrieve the relations array from CDCSimHits to CDCHits and fill it in to the local map which does the inverse mapping.
void	fillMCParticleByHitMap ()
	Retrieve the relations array from MCParticle to CDCHits and fill it in to the local map which does the inverse mapping.
void	fillMCParticleBySimHitMap ()
	Retrieve the relations array from MCParticle to CDCSimHits and fill it in to the local map which does the inverse mapping.
void	validateRelations () const
	Checks if the relations CDCHit -> MCParticle and CDCHit -> CDCSimHit -> MCParticle commute.
void	validateReassignedSecondaries () const
	Checks if each CDCHit is marked as reassigned secondary is related to a reassigned secondary CDCSimHit.

Static Private Member Functions
static bool	indicatesReassignedSecondary (double weight)
	Indicate if the given weight suggests that the corresponding hit to MCParticle relation has been redirected to point to a primary particle instead of the discarded secondary particle.

Private Attributes
std::multimap< const CDCHit *, const CDCSimHit * >	m_simHitsByHit
	Memory for a one to one relation from CDCHit to CDCSimHits.
std::multimap< const MCParticle *, const CDCHit * >	m_hitsByMCParticle
	Memory for a one to n relation from MCParticles to CDCHit.
std::multimap< const MCParticle *, const CDCSimHit * >	m_simHitsByMCParticle
	Memory for a one to n relation from MCParticles to CDCSimHit.
std::set< const CDCHit * >	m_reassignedSecondaryHits
	The set of reassigned secondary CDCHits.
std::set< const CDCSimHit * >	m_reassignedSecondarySimHits
	The set of reassigned secondary CDCSimHits.
