virtual TMatrixD* BaseEvtVtxGenerator::GetInvLorentzBoost ( )

pure virtual

Implemented in BetafuncEvtVtxGenerator, BeamProfileVtxGenerator, FlatEvtVtxGenerator, and GaussEvtVtxGenerator.

Referenced by produce().

virtual HepMC::FourVector* BaseEvtVtxGenerator::lastVertex ( )

inlinevirtual

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.
