Detailed Description

Abstract random number source.

The only RNG type core code may reference; concrete engines (the std-based QPRandom, the TRandom adapter in vis/include) are chosen and owned by the caller.

Constructor & Destructor Documentation

~QPRandomBase()

virtual QPRandomBase::~QPRandomBase ( )

inlinevirtual

Virtual destructor for deletion through the interface.

Definition at line 11 of file QPRandomBase.hpp.

Member Function Documentation

SetSeed()

virtual void QPRandomBase::SetSeed ( unsigned long  seed )

pure virtual

Seed the underlying engine.

Parameters

seed	engine seed value

Implemented in QPRandom, and QPRandomTRandom.

Uniform()

virtual double QPRandomBase::Uniform ( double  a, double  b  )

pure virtual

Uniform deviate between a and b.

Whether the endpoints themselves can be returned follows the concrete engine (QPRandom: ; the TRandom adapter: TRandom semantics).

Parameters

a	lower bound
b	upper bound

Returns

uniform deviate

Implemented in QPRandom, and QPRandomTRandom.

Referenced by QPMonteCarlo::Shoot().

Gaus()

virtual double QPRandomBase::Gaus ( double  mean, double  sigma  )

pure virtual

Normal (Gaussian) deviate.

Parameters

mean	mean of the distribution
sigma	standard deviation

Returns

normal deviate

Implemented in QPRandom, and QPRandomTRandom.
