getPrdsOnTrack()

std::vector< const Trk::PrepRawData * > Trk::PRDtoTrackMapTool::getPrdsOnTrack ( Trk::PRDtoTrackMap &  virt_prd_to_track_map, const Track &  track  ) const

overridevirtual

returns a vector of PRDs belonging to the passed track.

It's basically for the convenience of users and is created purely from the passed track. i.e. there is no caching if you do it multiple times on the same track, you're being inefficient!!

Parameters

track

this Track will be iterated through and all PrepRawData added to a vector

Returns

vector of PrepRawData* belonging to 'track'. The PrepRawData should NOT be deleted

• they belong to the Track (and thus the event).

Accept only non muon hits or muon precision hits
