Detailed Description

template<class AObject, class ARelationFilter>
class Belle2::TrackFindingCDC::WeightedRelationCreator< AObject, ARelationFilter >

Findlet that combines geometrical constrained pairs of objects to relations and selects them by the filter given as template parameter.

Template Parameters
AItemObject type on which relation should be created.
ARelationFilterSelection criterion to find the accepted relations.

In addition a parameter is exposed to only keep a fixed number of highest weighted relations from each segment.
