Member Function Documentation

◆ operator()() [1/2]

Weight operator() ( const Object &  obj)
virtualinherited

Function to evaluate the object.

Base implementation accepts all objects.

Parameters
objThe 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.

◆ operator()() [2/2]

Weight operator() ( const Object *  obj)
inherited

Function to evaluate the object.

Base implementation accepts all objects, except nullptr.

Parameters
objThe 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.
