std::independent_bits_engine
| | | | | ----------------------------------------------------------------------------------------------------------------------- | | ------------- | | template< class Engine, std::size_t W, class UIntType > class independent_bits_engine; | | (since C++11) |
independent_bits_engine is a random number engine adaptor that produces random numbers with different number of bits than that of the wrapped engine.
Contents
[edit] Template parameters
| Engine | - | the type of the wrapped engine |
|---|---|---|
| W | - | the number of bits the generated numbers should have |
| UIntType | - | the type of the generated random numbers. The effect is undefined unless the parameter is cv-unqualified and is one of unsigned short, unsigned int, unsigned long, or unsigned long long. |
| Type requirements | ||
| -Engine must meet the requirements of RandomNumberEngine. | ||
| -W must be greater than zero, and no greater than std::numeric_limits<UIntType>::digits. |

[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 (always zero). (public static member function) [edit] |
| max[static] (C++11) | gets the largest possible value in the output range (always 2w - 1). (public static member function) [edit] |
