InterfaceID.

virtual double IRndmEngine::rndm | ( | ) | const`[pure virtual]`

Single shot returning single random number.

virtual StatusCode IRndmEngine::rndmArray | ( | std::vector< double > & | array,
|  | long | howmany,
|  | long | start = `0`
| ) |  | const`[pure virtual]`

Multiple shots returning vector with flat random numbers.

Parameters:

  array | Array containing random numbers
  howmany | fill 'howmany' random numbers into array
  start | ... starting at position start

Returns:
  StatusCode indicating failure or success.

virtual StatusCode IRndmEngine::seeds | ( | std::vector< long > & | seeds ) | const`[pure virtual]`

Allow to retrieve seeds.

virtual StatusCode IRndmEngine::setSeeds | ( | const std::vector< long > & | seeds ) | `[pure virtual]`

Allow to set new seeds.
