Detailed Description

Reader for ascii files with e+e- pairs created from GuineaPig.

Reader for ascii files with e+e- pairs created from GuineaPig. Will read complete the file into one event - unless skip N events is called, then N particles are compiled into one event.

Constructor & Destructor Documentation

◆ Geant4EventReaderGuineaPig()

dd4hep::sim::Geant4EventReaderGuineaPig::Geant4EventReaderGuineaPig ( const std::string & nam )

explicit

Initializing constructor.

◆ ~Geant4EventReaderGuineaPig()

virtual dd4hep::sim::Geant4EventReaderGuineaPig::~Geant4EventReaderGuineaPig ( )

virtual

Default destructor.

Member Function Documentation

◆ moveToEvent()

virtual EventReaderStatus dd4hep::sim::Geant4EventReaderGuineaPig::moveToEvent ( int event_number )

overridevirtual

Move to the indicated event number.

For pure sequential access, the default implementation will skip events one by one. For technologies supporting direct event access the default implementation will be empty.

Returns

Reimplemented from dd4hep::sim::Geant4EventReader.

◆ readParticles()

virtual EventReaderStatus dd4hep::sim::Geant4EventReaderGuineaPig::readParticles	(	int	event_number,
		Vertices &	vertices,
		std::vector< Particle * > &	particles
