Private Types
using	Super = TrackFindingCDC::RelationFilter< CKFToPXDState >
	The parent class.

Private Attributes
int	m_param_hitJumping = 0
	Parameter: Make it possible to jump over N layers (if set to -1, read from DB).

int	m_layerJumpLowPt = m_param_hitJumping
	This are values that are actually used ('m_param_hitJumping==-1' means parameter is read from DB).

int	m_layerJumpHighPt = m_param_hitJumping
	This are values that are actually used ('m_param_hitJumping==-1' means parameter is read from DB).

double	m_layerJumpPtThreshold = -1
	This are values that are actually used ('m_param_hitJumping==-1' means parameter is read from DB).

AFilter	m_filter
	Filter for rejecting the states.

APrefilter	m_prefilter
	Loose pre-filter to reject possibleTos.

std::string	m_prefix = ""
	Used to get correct payload.

std::unique_ptr< DBObjPtr< CKFParameters > >	m_ckfParameters
	LayerJump parameter can be read from DB (use pointer as payload name contains 'prefix')

	References to subordinary signal processing listener contained in this findlet.

bool	m_initialized = false
	Flag to keep track whether initialization happend before.

bool	m_terminated = false
	Flag to keep track whether termination happend before.

std::string	m_initializedAs
	Name of the type during initialisation.

Member Function Documentation

◆ operator()() [1/4]

Weight operator()	(	const CKFToPXDState &	from,
		const CKFToPXDState &	to
	)

virtualinherited

Main filter method returning the weight of the neighborhood relation.

Return always returns NAN to reject all segment neighbors.

Definition at line 44 of file RelationFilter.icc.h.

     {
       return 1;
     }

◆ operator()() [2/4]

Weight operator() ( const Object & obj )

virtualinherited

Function to evaluate the object.

Base implementation accepts all objects.

Parameters

obj	The object to be accepted or rejected.

Returns: A finite float value if the object is accepted. NAN if the object is rejected.

Reimplemented in AllSVDStateFilter, SimpleSVDStateFilter, ResidualSVDStateFilter, AllPXDStateFilter, SimplePXDStateFilter, TwoHitVirtualIPQIFilter, TwoHitVirtualIPFilter, ThreeHitFilter, QualityIndicatorFilter, FourHitFilter, FiveHitFilter, RoughCDCStateFilter, RoughCDCfromEclStateFilter, MCTruthEclSeedFilter, MCTruthCDCStateFilter, ExtrapolateAndUpdateCDCStateFilter, DistanceCDCStateFilter, MCTruthCDCPathPairFilter, HitDistanceBasedCDCPathPairFilter, DuplicateCDCPathPairFilter, DistanceBasedCDCPathPairFilter, Chi2BasedCDCPathPairFilter, ArcLengthBasedCDCPathPairFilter, ArcLengthBasedCDCfromEclPathPairFilter, SizeCDCPathFilter, and SeedChargeCDCPathFilter.

Definition at line 52 of file Filter.icc.h.

◆ operator()() [3/4]

Weight operator() ( const Object * obj )

inherited

Function to evaluate the object.

Base implementation accepts all objects, except nullptr.

Parameters

obj	The object to be accepted or rejected.

Returns: A finit float value if the object is accepted. NAN if the object is rejected. Nullptr is always rejected.

Definition at line 58 of file Filter.icc.h.

◆ operator()() [4/4]

Weight operator() ( const Relation< CKFToPXDState > & relation )

overrideinherited

Main filter method overriding the filter interface method.

Checks the validity of the pointers in the relation and unpacks the relation to the method implementing the rejection.
