RandomSelectors

Contains ResultSelector's to be used with a java.util.stream.Stream as a collection operation.

Functions

scaledSd

static ResultSelector<T> scaledSd<T>(double sdPercent)

Creates a result selector that randomly selects an element where the element index is selected with the formula:

var resultIndex = randomSd(0, list.size() - 1, 0, sdPercent * list.size())

where randomSd generates a random number from a normal distribution with the parameters min/max/mean/sd

static ResultSelector<T> scaledSd<T>(double meanPercent, double sdPercent)

Creates a result selector that randomly selects an element where the element index is selected with the formula:

var resultIndex = randomSd(0, list.size() - 1, meanPercent * (list.size() - 1), sdPercent * list.size())

where randomSd generates a random number from a normal distribution with the parameters min/max/mean/sd

uniform

Creates a result selector that randomly selects an element using a uniform distribution

weighted

Creates a result selector that randomly selects an element where each element is given a specific weight based on the weight extractor function.
