Member Function Documentation

virtual TMatrixD const* BaseEvtVtxGenerator::GetInvLorentzBoost ( ) const

pure virtual

This method - and the comment - is a left-over from COBRA-OSCAR time : return the last generated event vertex. If no vertex has been generated yet, a NULL pointer is returned.

Implemented in BetafuncEvtVtxGenerator, HLLHCEvtVtxGenerator, BeamProfileVtxGenerator, FlatEvtVtxGenerator, and GaussEvtVtxGenerator.

virtual HepMC::FourVector BaseEvtVtxGenerator::newVertex ( CLHEP::HepRandomEngine *  ) const

pure virtual

Implemented in BetafuncEvtVtxGenerator, HLLHCEvtVtxGenerator, BeamProfileVtxGenerator, FlatEvtVtxGenerator, and GaussEvtVtxGenerator.
