Returns
a pointer to the new object.

Implements ThePEG::InterfacedBase.

◆ doinit()

virtual void Herwig::DipoleMatching::doinit ( )
protectedvirtual

Initialize this object after the setup phase before saving an EventGenerator to disk.

Exceptions
InitExceptionif object could not be initialized properly.

Reimplemented from Herwig::ShowerApproximation.

◆ fullclone()

virtual IBPtr Herwig::DipoleMatching::fullclone ( ) const
protectedvirtual
