Detailed Description

The DecayHandler is the base class of all handlers implementing the administration of decays of unstable particles.

It is derived from the more general StepHandler class, and overrides the handle() method. This base class simply decays all unstable particle in the current step.

Member Function Documentation

virtual void ThePEG::DecayHandler::handle	(	EventHandler &	eh,
		const tPVector &	tagged,
		const Hint &	hint
	)			[virtual]

Look through all tagged particled and decay all unstable ones.

Parameters:

	eh	the EventHandler in charge of the generation.
	tagged	the vector of particles to consider. If empty, all final state particles in the current Step is considered.
	hint	a possible Hint which is ignored in this implementation.

Implements ThePEG::StepHandler.

void ThePEG::DecayHandler::performDecay	(	tPPtr	parent,
		Step &	s
	)			const

Perform the decay of one unstable particle.

Parameters:

	parent	the particle to be decayed.
	s	the Step where decay products are inserted.

void ThePEG::DecayHandler::persistentOutput

(

PersistentOStream &

os

)

const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::Interfaced.

void ThePEG::DecayHandler::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 ThePEG::Interfaced.

virtual IBPtr ThePEG::DecayHandler::clone

(

)

const [protected, virtual]

Make a simple clone of this object.

Returns:

a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::DecayHandler::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 ThePEG::InterfacedBase.
