Member Function Documentation

◆ analyze()

virtual void ThePEG::HepMC3File::analyze	(	tEventPtr	event,
		long	ieve,
		int	loop,
		int	state
	)

virtual

Analyze a given Event.

Note that a fully generated event may be presented several times, if it has been manipulated in between. The default version of this function will call transform to make a lorentz transformation of the whole event, then extract all final state particles and call analyze(tPVector) of this analysis object and those of all associated analysis objects. The default version will not, however, do anything on events which have not been fully generated, or have been manipulated in any way.

Parameters

event	pointer to the Event to be analyzed.
ieve	the event number.
loop	the number of times this event has been presented. If negative the event is now fully generated.
state	a number different from zero if the event has been manipulated in some way since it was last presented.

Reimplemented from ThePEG::AnalysisHandler.

◆ clone()

virtual IBPtr ThePEG::HepMC3File::clone ( ) const

protectedvirtual

void ThePEG::HepMC3File::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

is	the persistent input stream read from.
version	the version number of the object when written.

◆ persistentOutput()

void ThePEG::HepMC3File::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.
