List of all members.

Public Member Functions
virtual bool	isUnweighting () const
	Return true, if this bin sampler produces unweighted events.
virtual bool	compensating () const
	Return true, if this sampler is in a compensating mode.
virtual void	generate (bool noMaxInfo=false)

virtual void	initialize (bool progress)
	Initialize this bin sampler.
virtual void	finalize (bool verbose)
	Finalize this sampler.
virtual void	reject ()
	Reject an event.
double	evaluate (const vector< double > &p) const
	Evaluate with given random numbers.
pair< vector< double >, vector < double > >	support () const
	Return the lower left and upper right corners of the support of this function.
void	start_presampling ()
	Indicate start of presampling.
void	stop_presampling ()
	Indicate end of presampling.
Standard constructors and destructors.

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

	The assignment operator is private and must never be called.
Private Attributes
unsigned long	presampling_points_
	The number of presampling points.
unsigned long	freeze_grid_
	The number of points below which the grid is frozen.
double	efficiency_threshold_
	The efficiency threshold.

Member Function Documentation

virtual IBPtr Herwig::ExSampler::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::ExSampler::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::ExSampler::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::ExSampler::initialize

(

bool

progress

)

[virtual]

Initialize this bin sampler.

This default version calls runIteration.

Reimplemented from Herwig::BinSampler.

ExSampler& Herwig::ExSampler::operator=

(

const ExSampler &

)

[private]

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

void Herwig::ExSampler::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::ExSampler::persistentOutput

(

PersistentOStream &

os

)

const

Function used to write out object persistently.

Parameters:

os	the persistent output stream written to.

Reimplemented from Herwig::BinSampler.
