int PHActsVertexPropagator::Init ( PHCompositeNode *  )
overridevirtual

Called during initialization. Typically this is where you can book histograms, and e.g. register them to Fun4AllServer (so they can be output to file using Fun4AllServer::dumpHistos() method).

Reimplemented from SubsysReco.

References Fun4AllReturnCodes::EVENT_OK.

int PHActsVertexPropagator::InitRun ( PHCompositeNode *  )
overridevirtual

Called for first event when run number is known. Typically this is where you may want to fetch data from database, because you know the run number.

Reimplemented from SubsysReco.

Called for each event. This is where you do the real work.

Key was removed by the track cleaner, remove it from the trajectory list too

Erase the trajectories that were removed from the track cleaner
