CloseInput()

void Pythia6Generator::CloseInput ( )

private

Verbose Level.

Private method CloseInput. Just for convenience. Closes the input file properly. Called from destructor and from ReadEvent.

Definition at line 111 of file Pythia6Generator.cxx.

ReadEvent()

Bool_t Pythia6Generator::ReadEvent ( FairPrimaryGenerator *  primGen )

virtual

Reads on event from the input file and pushes the tracks onto the stack. Abstract method in base class.

Parameters

primGen

pointer to the CbmrimaryGenerator
