## Detailed Description

Random Generator service interface definition Definition of a interface for a service to access random generators according to predefined distributions:

The Random Generator creates proper instances of requested random generators and delivers them to the user.

On request the service dumps the type and state of the random number engine to a StreamBuffer object allowing to save and to restore the exact state of the random number generator.
