Detailed Description

template<typename _IntType = int>
class std::uniform_int< _IntType >

Uniform discrete distribution for random numbers. A discrete random distribution on the range $[min, max]$ with equal probability throughout the range.

Member Typedef Documentation

template<typename _IntType = int>
typedef _IntType std::uniform_int< _IntType >::input_type

The type of the parameters of the distribution.

Definition at line 1566 of file tr1_impl/random.

template<typename _IntType = int>
typedef _IntType std::uniform_int< _IntType >::result_type

The type of the range of the distribution.

Definition at line 1568 of file tr1_impl/random.


Constructor & Destructor Documentation

template<typename _IntType = int>
std::uniform_int< _IntType >::uniform_int ( _IntType  __min = 0,
_IntType  __max = 9 
)
inlineexplicit

Constructs a uniform distribution object.

Definition at line 1575 of file tr1_impl/random.


Member Function Documentation

template<typename _IntType = int>
result_type std::uniform_int< _IntType >::max ( ) const
inline

Gets the inclusive upper bound of the distribution range.

Definition at line 1592 of file tr1_impl/random.

template<typename _IntType = int>
result_type std::uniform_int< _IntType >::min ( ) const
inline

Gets the inclusive lower bound of the distribution range.

Definition at line 1585 of file tr1_impl/random.

template<typename _IntType = int>
template<typename _UniformRandomNumberGenerator >
result_type std::uniform_int< _IntType >::operator() ( _UniformRandomNumberGenerator &  __urng)
inline
    Gets a uniformly distributed random number in the range

$(min, max)$.

Definition at line 1609 of file tr1_impl/random.

template<typename _IntType = int>
template<typename _UniformRandomNumberGenerator >
result_type std::uniform_int< _IntType >::operator() ( _UniformRandomNumberGenerator &  __urng,
result_type  __n 
)
inline

Gets a uniform random number in the range $[0, n)$.

This function is aimed at use with std::random_shuffle.

Definition at line 1624 of file tr1_impl/random.

template<typename _IntType = int>
void std::uniform_int< _IntType >::reset ( )
inline

Resets the distribution state.

Does nothing for the uniform integer distribution.
