◆ SpinHadronizer()

Herwig::SpinHadronizer::SpinHadronizer ( )
inline

The default constructor.

Member Function Documentation

◆ baryonSpin()

void Herwig::SpinHadronizer::baryonSpin ( tPPtr  baryon)
protected

Functions to calculate the spins.

Calculate the spin of a baryon

◆ clone()

virtual IBPtr Herwig::SpinHadronizer::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ dofinish()

virtual void Herwig::SpinHadronizer::dofinish ( )
protectedvirtual

Finalize this object.

Called in the run phase just after a run has ended. Used eg. to write out statistics.

Reimplemented from ThePEG::InterfacedBase.

◆ doinit()

virtual void Herwig::SpinHadronizer::doinit ( )
protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from ThePEG::InterfacedBase.

◆ doinitrun()

virtual void Herwig::SpinHadronizer::doinitrun ( )
protectedvirtual

Initialize this object.

Called in the run phase just before a run begins.

Reimplemented from ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::SpinHadronizer::fullclone ( ) const
protectedvirtual

Make a clone of this object, possibly modifying the cloned object to make it sane.

Returns
a pointer to the new object.

Reimplemented from ThePEG::InterfacedBase.

◆ handle()

virtual void Herwig::SpinHadronizer::handle ( EventHandler eh,
const tPVector tagged,
const Hint hint 
)
virtual

The main function called by the EventHandler class to perform a step.

Given the current state of an Event, this function performs the event generation step and includes the result in a new Step object int the Event record.

Parameters
ehthe EventHandler in charge of the Event generation.
taggedif not empty these are the only particles which should be considered by the StepHandler.
hinta Hint object with possible information from previously performed steps.
Exceptions
Vetoif the StepHandler requires the current step to be discarded.
Stopif the generation of the current Event should be stopped after this call.
Exceptionif something goes wrong.

Implements ThePEG::StepHandler.

◆ Init()

static void Herwig::SpinHadronizer::Init ( )
static

The standard Init function used to initialize the interfaces.

Called exactly once for each class by the class description system before the main function starts or when this class is dynamically loaded.

◆ operator=()

SpinHadronizer & Herwig::SpinHadronizer::operator= ( const SpinHadronizer )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::SpinHadronizer::persistentInput ( PersistentIStream is,
int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
versionthe version number of the object when written.

◆ persistentOutput()

void Herwig::SpinHadronizer::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
