Detailed Description

Class for generating random numbers.

Generators that need to produce random numbers in a thread-safe way should inherit from this class and call this->rand(...) to get random numbers.

Constructor & Destructor Documentation

rand_gen()

stapl::generators::rand_gen::rand_gen

(

unsigned int

seed = get_location_id()

)

Parameters

seed	The seed for random-number generation.

Member Function Documentation

rand() [1/2]

size_t stapl::generators::rand_gen::rand

(

size_t

max

)

Generates a random number in the range [0, max).

Parameters

max	The maximum value of the output random number (exclusive).

rand() [2/2]

size_t stapl::generators::rand_gen::rand	(	size_t	min,
		size_t	max
	)

Generates a random number in the range [min, max).

Parameters

min	The minimum value of the output random number.
max	The maximum value of the output random number (exclusive).
