List of all members.

Public Member Functions
virtual void	generate (bool noMaxInfo=false)
	Generate the next point; store the point in lastPoint() and its weight using select(); if noMaxInfo is true, do not throw NewMaximum or UpdateCrossSections exceptions.
virtual void	initialize (bool progress)
	Initialize this bin sampler.
void	adapt ()
	Finish an iteration, performing the adaption.
virtual void	select (double weight)
	Select an event.
virtual void	accept ()
	Accept an event.
virtual void	reject ()
	Reject an event.
Standard constructors and destructors.
	ProjectingSampler ()
	The default constructor.
virtual	~ProjectingSampler ()
	The destructor.
Functions used by the persistent I/O system.
void	persistentOutput (PersistentOStream &os) const
	Function used to write out object persistently.
void	persistentInput (PersistentIStream &is, int version)
	Function used to read in object persistently.
Static Public Member Functions
static void	Init ()
	The standard Init function used to initialize the interfaces.
Protected Member Functions
Clone Methods.
virtual IBPtr	clone () const
	Make a simple clone of this object.
virtual IBPtr	fullclone () const
	Make a clone of this object, possibly modifying the cloned object to make it sane.
Private Member Functions
ProjectingSampler &	operator= (const ProjectingSampler &)
	The assignment operator is private and must never be called.
Private Attributes
bool	theFirstIteration
	True, if we're running the first iteration.
unsigned long	theNIterations
	The number of iterations to be considered for initialization.
double	theEnhancementFactor
	Factor to enhance the number of points for the next iteration.
unsigned int	theNBins
	The initial number of bins to use.
double	theEpsilon
	The adaption threshold.
unsigned long	theLastNPoints
	The number of points used for the last iteration.
vector< BinnedStatistics >	theProjections
	The projections to use.
double	theLastValue
	The last integrand value.
double	theWeightThreshold
	The weight threshold which governs the minimum bin weight.

Member Function Documentation

virtual IBPtr Herwig::ProjectingSampler::clone

(

)

const [protected, virtual]

Make a simple clone of this object.

Returns:

a pointer to the new object.

Reimplemented from Herwig::BinSampler.

virtual IBPtr Herwig::ProjectingSampler::fullclone

(

)

const [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 Herwig::BinSampler.

static void Herwig::ProjectingSampler::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 Herwig::BinSampler.

virtual void Herwig::ProjectingSampler::initialize

(

bool

progress

)

[virtual]

Initialize this bin sampler.

This default version calls runIteration.

Reimplemented from Herwig::BinSampler.

ProjectingSampler& Herwig::ProjectingSampler::operator=

(

const ProjectingSampler &

)

[private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

void Herwig::ProjectingSampler::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.

Reimplemented from Herwig::BinSampler.

void Herwig::ProjectingSampler::persistentOutput

(

PersistentOStream &

os

)

const

Function used to write out object persistently.

Parameters:

os	the persistent output stream written to.

Reimplemented from Herwig::BinSampler.
