◆ GetInvLorentzBoost()

TMatrixD const* PassThroughEvtVtxGenerator::GetInvLorentzBoost ( ) const

inlineoverridevirtual

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.

Implements BaseEvtVtxGenerator.
