Member Function Documentation

◆ clone()

virtual IBPtr Herwig::FFLightInvertedTildeKinematics::clone ( ) const
protectedvirtual

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ doMap()

virtual bool Herwig::FFLightInvertedTildeKinematics::doMap ( const double *  )
virtual

Perform the mapping of the tilde kinematics for the last selected process and store all dimensionless variables in the subtractionParameters() vector.

Return false, if the calculation of the real kinematics was impossible for the selected configuration and true on success.

Implements Herwig::InvertedTildeKinematics.

◆ fullclone()

virtual IBPtr Herwig::FFLightInvertedTildeKinematics::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::InterfacedBase.

◆ Init()

static void Herwig::FFLightInvertedTildeKinematics::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=()

FFLightInvertedTildeKinematics& Herwig::FFLightInvertedTildeKinematics::operator= ( const FFLightInvertedTildeKinematics )
private

The assignment operator is private and must never be called.

In fact, it should not even be implemented.

◆ persistentInput()

void Herwig::FFLightInvertedTildeKinematics::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 Herwig::FFLightInvertedTildeKinematics::persistentOutput ( PersistentOStream os) const

Function used to write out object persistently.

Parameters
osthe persistent output stream written to.
