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.

Definition at line 42 of file BaseEvtVtxGenerator.h.

References fVertex.

{ return fVertex; }

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

pure virtual

Implemented in BetafuncEvtVtxGenerator, BeamProfileVtxGenerator, FlatEvtVtxGenerator, and GaussEvtVtxGenerator.

void BaseEvtVtxGenerator::produce ( edm::Event &  evt, const edm::EventSetup &    )
