std::shuffle_order_engine
| | | | | ---------------------------------------------------------------------------------------------------- | | ------------- | | template< class Engine, std::size_t K > class shuffle_order_engine; | | (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:
Contents
- 1 Template parameters
- 2 Member types
- 3 Member functions
- 4 Non-member functions
- 5 Member objects
- 6 Example
[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. |
[edit] Member types
| Member type | Definition |
|---|---|
| result_type (C++11) | Engine::result_type |
[edit] Member functions
| (constructor)(C++11) | constructs the engine adaptor (public member function) [edit] |
|---|---|
| seed(C++11) | sets the state of the underlying engine (public member function) [edit] |
| base(C++11) | returns the underlying engine (public member function) [edit] |
| Generation | |
| operator()(C++11) | advances the state of the underlying engine and returns the generated value (public member function) [edit] |
| discard(C++11) | advances the adaptor's state by a specified amount (public member function) [edit] |
| Characteristics | |
| min[static] (C++11) | gets the smallest possible value in the output range of the underlying engine. (public static member function) [edit] |
| max[static] (C++11) | gets the largest possible value in the output range of the underlying engine. (public static member function) [edit] |
[edit] Non-member functions
[edit] Member objects
| constexpr size_t table_size[static] (C++11) | the size of the internal table, K (public static member constant) |
