Detailed Description

template<class AHit, class AFilter>
class Belle2::vxdHoughTracking::LimitedOnHitApplier< AHit, AFilter >

Specialisation of the OnHitApplier, which (a) uses a filter for the () operator, which is configurable (b) does only allow for the best N candidates in the child hits.

All other hits will be deleted.

If m_useNHits is 0, all hits are used.
