Detailed Description

The XSecCheck class is a simple analysis class used for testing purposes.

If the total cross section does not match the one specified by TargetXSec, an exception will be thrown.

Constructor & Destructor Documentation

◆ XSecCheck()

ThePEG::XSecCheck::XSecCheck ( )
inline

The default constructor.

Definition at line 28 of file XSecCheck.h.

Member Function Documentation

◆ analyze()

virtual void ThePEG::XSecCheck::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.

◆ clone()

virtual IBPtr ThePEG::XSecCheck::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Reimplemented from ThePEG::AnalysisHandler.

◆ dofinish()

virtual void ThePEG::XSecCheck::dofinish ( )
protectedvirtual

Finalize this object.

Reimplemented from ThePEG::InterfacedBase.

◆ doinitrun()

virtual void ThePEG::XSecCheck::doinitrun ( )
inlineprotectedvirtual

Initialize this object.

Called in the run phase just before a run begins.

References ThePEG::InterfacedBase::doinitrun(), and sumw.

◆ fullclone()

virtual IBPtr ThePEG::XSecCheck::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::AnalysisHandler.

◆ Init()

static void ThePEG::XSecCheck::Init ( )
static

◆ operator=()

XSecCheck & ThePEG::XSecCheck::operator= ( const XSecCheck )
privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void ThePEG::XSecCheck::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 ThePEG::XSecCheck::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
