Detailed Description

Simple equidistant sampler of the unit interval conforming to the AbsRandomGenerator interface. Imagine that the interval [0,1] is split into bins, like in a histogram. The samples will be taken in the middle of those bins – either from left to right of from right to left, depending on the value of "increasingOrder" costructor parameter.

Member Function Documentation

◆ dim()

unsigned npstat::EquidistantSampler1D::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.

◆ maxPoints()

unsigned long long npstat::EquidistantSampler1D::maxPoints ( ) const

inlinevirtual

Maximum number of points which can be meaningfully produced by this generator (this is usually the generator period). If 0 is returned, it means that this number is larger than the maximum value of unsigned long long (which is typically 2^64 - 1). Override as necessary.

Reimplemented from npstat::AbsRandomGenerator.

◆ operator()()

double npstat::EquidistantSampler1D::operator() ( )

virtual

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