Detailed Description

The MultiPartonExtractor class inherits from the PartonExtractor of ThePEG but allows more control over the PDFs used in the case that there are multiple stages of parton extraction.

See also: The interfaces defined for MultiPartonExtractor.

Constructor & Destructor Documentation

◆ MultiPartonExtractor()

Herwig::MultiPartonExtractor::MultiPartonExtractor ( )

inline

The default constructor.

Definition at line 30 of file MultiPartonExtractor.h.

Member Function Documentation

◆ clone()

virtual IBPtr Herwig::MultiPartonExtractor::clone ( ) const

protectedvirtual

Make a simple clone of this object.

Returns: a pointer to the new object.

Reimplemented from ThePEG::PartonExtractor.

◆ fullclone()

virtual IBPtr Herwig::MultiPartonExtractor::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::PartonExtractor.

◆ getPartons()

virtual PartonPairVec Herwig::MultiPartonExtractor::getPartons	(	Energy	maxEnergy,
		const cPDPair &	,
		const Cuts &
	)		const

virtual

Return a vector of possible pairs of parton bins which can be produced within a given maximum total particle-particle invariant mass squared, maxEnergy sBin.

Reimplemented from ThePEG::PartonExtractor.

◆ Init()

static void Herwig::MultiPartonExtractor::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=()

MultiPartonExtractor & Herwig::MultiPartonExtractor::operator= ( const MultiPartonExtractor & )

privatedelete

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::MultiPartonExtractor::persistentInput	(	PersistentIStream &	is,
		int	version
	)

Function used to read in object persistently.

Parameters

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

◆ persistentOutput()

void Herwig::MultiPartonExtractor::persistentOutput ( PersistentOStream & os ) const

Function used to write out object persistently.

Parameters

os	the persistent output stream written to.
