| (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.
| 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. |

| Member type | Definition |
|---|---|
result_type (C++11) | UIntType |
|
(C++11) | constructs the engine adaptor (public member function) |
|
(C++11) | sets the state of the underlying engine (public member function) |
|
(C++11) | returns the underlying engine (public member function) |
Generation |
|
|
(C++11) | advances the state of the underlying engine and returns the generated value (public member function) |
|
(C++11) | advances the adaptor's state by a specified amount (public member function) |
Characteristics |
|
|
[static] (C++11) | gets the smallest possible value in the output range (always zero). (public static member function) |
|
[static] (C++11) | gets the largest possible value in the output range (always 2w - 1). (public static member function) |
|
(C++11)(C++11)(removed in C++20) | compares the internal states of the adaptors and underlying engines (function) |
|
(C++11) | performs stream input and output on pseudo-random number engine adaptor (function) |
