Detailed Description

template<typename RandomEngine>
class npstat::CPP11RandomGen< RandomEngine >

Wrapper class for random number generators defined in the C++11 standard. This class will not make a copy of the original generator, only a reference to it is stored. You will not be able to use this class in a meaningful way unless you have a C++11-compliant compiler which provides the <random> header.

The template type should be one of the random engines defined by C++11. Example:

std::random_device rd; std::mt19937 eng(rd()); npstat::CPP11RandomGen<decltype(eng)> gen(eng);

Now, gen() will produce pseudo-random numbers.

Member Function Documentation

dim()

template<typename RandomEngine >

unsigned npstat::CPP11RandomGen< RandomEngine >::dim ( ) const

inlinevirtual

Dimensionality of the generated vectors (or points). It is expected that "dim()" will always be 1 for pseudo-random (as opposed to quasi-random) generators.

Implements npstat::AbsRandomGenerator.

operator()()

template<typename RandomEngine >

double npstat::CPP11RandomGen< RandomEngine >::operator() ( )

inlinevirtual

Standard 1-d generator function. It should generate a run-time error for essentially multivariate generators whose dimensionality is larger than 1.

Implements npstat::AbsRandomGenerator.
