Member Function Documentation

virtual void ThePEG::StandardRandom::setSeed

(

long

seed

)

[virtual]

Reset the underlying random algorithm with the given seed.

If the seed is set to -1 a standard seed will be used.

Implements ThePEG::RandomGenerator.

Referenced by StandardRandom().

void ThePEG::StandardRandom::persistentOutput

(

PersistentOStream &

os

)

const

Function used to write out object persistently.

Parameters:

os

the persistent output stream written to.

Reimplemented from ThePEG::RandomGenerator.

void ThePEG::StandardRandom::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::RandomGenerator.

virtual IBPtr ThePEG::StandardRandom::clone

(

)

const [protected, virtual]

Make a simple clone of this object.

Returns:

a pointer to the new object.

Implements ThePEG::InterfacedBase.

virtual IBPtr ThePEG::StandardRandom::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.
