Detailed Description

The random number generator class used internally in the Pythia7 Shower routines.

This should be replaced with the ThePEG RandomGenerator. Uses only static methods.

Default constructor.

)

[inline]

Standard constructor giving a seed.

Note that although this looks like a new Rndm object is constructed with a separate random number sequence, the underlying static generator is reinitialized.
