Detailed Description

Weighted random integer generator.

Generate random integers according different probabilities

Definition at line 91 of file random_number_generator.h.

Constructor & Destructor Documentation

isc::util::random::WeightedRandomIntegerGenerator::WeightedRandomIntegerGenerator	(	const std::vector< double > &	probabilities,
		size_t	min = `0`
	)

inline

Constructor.

Parameters

probabilities	The probabilities for all the integers, the probability must be between 0 and 1.0, the sum of probabilities must be equal to 1. For example, if the probabilities contains the following values: 0.5 0.3 0.2, the 1st integer will be generated more frequently than the other integers and the probability is proportional to its value.
min	The minimum integer that generated, other integers will be min, min + 1, ..., min + probabilities.size() - 1
