std::independent_bits_engine
Defined in header <random> | ||
|---|---|---|
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.
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 type must be unsigned integral type. |
| Type requirements | ||
-Engine must meet the requirements of RandomNumberEngine. |
||
-W must be greater than zero, and no greater than std::numeric_limits<UIntType>::digits. |

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