std::shuffle_order_engine: std::shuffle_order_engine

NAME

std::shuffle_order_engine - std::shuffle_order_engine

Synopsis

Defined in header <random>
template<
class Engine, (since C++11)
std::size_t K
> class shuffle_order_engine;

shuffle_order_engine is a random number engine adaptor that shuffles the random numbers generated by the base engine. It maintains a table of size K and delivers a randomly selected number from that table when requested, replacing it with a number generated by the base engine.
The following typedef defines the random number engine with one commonly used parameter set:

Defined in header <random>
Type Definition
knuth_b(C++11) std::shuffle_order_engine<std::minstd_rand0, 256>

Template parameters

Engine - the type of the wrapped engine
K - the size of the internal table. Must be greater than 0

Type requirements

-
Engine must meet the requirements of RandomNumberEngine.

Member types

Member functions

              constructs the engine adaptor
constructor (public member function)
              sets the state of the underlying engine
seed (public member function)
              returns the underlying engine
base (public member function)

Generation

              advances the state of the underlying engine and returns the generated value
operator() (public member function)
              advances the adaptor's state by a specified amount
discard (public member function)

Characteristics

min gets the smallest possible value in the output range of the underlying engine.
