Member Function Documentation

virtual void Herwig::EtaDecayAnalysis::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:
eventpointer to the Event to be analyzed.
ievethe event number.
loopthe number of times this event has been presented. If negative the event is now fully generated.
statea number different from zero if the event has been manipulated in some way since it was last presented.

Reimplemented from ThePEG::AnalysisHandler.

virtual void Herwig::EtaDecayAnalysis::analyze ( const tPVector particles) [virtual]

Analyze the given vector of particles.

The default version calls analyze(tPPtr) for each of the particles.

Parameters:
particlesthe vector of pointers to particles to be analyzed

Reimplemented from ThePEG::AnalysisHandler.

virtual void Herwig::EtaDecayAnalysis::analyze ( tPPtr  particle) [virtual]

Analyze the given particle.

Parameters:
particlepointer to the particle to be analyzed.

Reimplemented from ThePEG::AnalysisHandler.

virtual IBPtr Herwig::EtaDecayAnalysis::clone ( ) const [inline, protected, virtual]

Make a simple clone of this object.

Returns:
a pointer to the new object.

Reimplemented from ThePEG::AnalysisHandler.

Definition at line 80 of file EtaDecayAnalysis.h.

virtual void Herwig::EtaDecayAnalysis::dofinish ( ) [protected, virtual]

Finalize this object.

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

Reimplemented from ThePEG::InterfacedBase.

virtual void Herwig::EtaDecayAnalysis::doinitrun ( ) [protected, virtual]

Initialize this object.

Called in the run phase just before a run begins.

Reimplemented from ThePEG::InterfacedBase.

virtual IBPtr Herwig::EtaDecayAnalysis::fullclone ( ) const [inline, protected, virtual]

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::AnalysisHandler.

Definition at line 86 of file EtaDecayAnalysis.h.

static void Herwig::EtaDecayAnalysis::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.

Reimplemented from ThePEG::AnalysisHandler.

EtaDecayAnalysis& Herwig::EtaDecayAnalysis::operator= ( const EtaDecayAnalysis ) [private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.
