Public Types
using	WeightedRelationItem = WeightedRelation< CDCTrack, const CDCRLWireHit >
	Shortcut class name for a weighted relation between a collector item and a collection item.
using	IOTypes = std::tuple< AIOTypes... >
	Types that should be served to apply on invokation.

virtual std::string	getDescription ()
	Brief description of the purpose of the concret findlet.
virtual void	exposeParameters (ModuleParamList *moduleParamList __attribute__((unused)), const std::string &prefix __attribute__((unused)))
	Forward prefixed parameters of this findlet to the module parameter list.
void	initialize () override
	Receive and dispatch signal before the start of the event processing.
void	beginRun () override
	Receive and dispatch signal for the beginning of a new run.
void	beginEvent () override
	Receive and dispatch signal for the start of a new event.
void	endRun () override
	Receive and dispatch signal for the end of the run.
void	terminate () override
	Receive and dispatch Signal for termination of the event processing.

Protected Types
using	ToVector = typename ToVectorImpl< T >::Type
	Short hand for ToRangeImpl.

Protected Member Functions
virtual void	add (CDCTrack &collectorItem __attribute__((unused)), const CDCRLWireHit &collectionItem __attribute__((unused)), Weight weight __attribute__((unused)))
