Implemented in HepRndm::Generator< Rndm::DefinedPdf >, and RndmGen.

virtual long IRndmGen::ID | ( | ) | const`[pure virtual]`

Random generator ID.

Implemented in RndmGen.

virtual StatusCode IRndmGen::initialize | ( | const IRndmGen::Param & | par ) | `[pure virtual]`

Initialize the generator.

Implemented in HepRndm::Generator< TYPE >, HepRndm::Generator< Rndm::DefinedPdf >, and RndmGen.

virtual const IRndmGen::Param* IRndmGen::parameters | ( | ) | const`[pure virtual]`

Access to random number generator parameters.

Implemented in RndmGen.

virtual double IRndmGen::shoot | ( | ) | const`[pure virtual]`

Single shot returning single random number according to specified distribution.

Implemented in HepRndm::Generator< TYPE >, HepRndm::Generator< Rndm::DefinedPdf >, RndmGen, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, HepRndm::Generator< TYPE >, and HepRndm::Generator< TYPE >.

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

Multiple shots returning vector with random number according to specified distribution.

Parameters:

  array | Array containing random numbers
  howmany | fill 'howmany' random numbers into array
  start | ... starting at position start
  Statuscode | indicating success or failure

Implemented in RndmGen.

virtual const InterfaceID& IRndmGen::type | ( | ) | const`[pure virtual]`
