Member Function Documentation

◆ clone()

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

Make a simple clone of this object.

Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ fullclone()

virtual IBPtr Herwig::FFggxDipole::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::FFggxDipole::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=()

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

int  version 
)

Function used to read in object persistently.

Parameters
isthe persistent input stream read from.
