(since C++11) | |
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:
| Type | Definition |
knuth_b (C++11)

std::shuffle_order_engine<std::minstd_rand0, 256>[edit]
|
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.
