Constructor & Destructor Documentation

◆ SubProcessGroup()

ThePEG::SubProcessGroup::SubProcessGroup ( const PPair newIncoming,
tCollPtr  newCollision = tCollPtr(),
tcEventBasePtr  newHandler = tcEventBasePtr() 
)

Standard constructor.

Parameters
newIncomingthe two incoming partons.
newCollisionthe Collision to which this SubProcessGroup belongs.
newHandlerthe MEBase object which generated this SubProcessGroup.

Member Function Documentation

◆ Init()

static void ThePEG::SubProcessGroup::Init ( )
static

Standard Init function.

See also
Base::Init().

Referenced by add().

◆ rebind()

virtual void ThePEG::SubProcessGroup::rebind ( const EventTranslationMap trans)
protectedvirtual

Rebind to cloned objects.

When a SubProcessGroup is cloned, a shallow copy is done first, then all Particles etc, are cloned, and finally this method is used to see to that the pointers in the cloned SubProcessGroup points to the cloned Particles etc.

Reimplemented from ThePEG::SubProcess.
