fcppt::random::distribution::basic< Parameters > Class Template Reference

Detailed Description

template<typename Parameters>
class fcppt::random::distribution::basic< Parameters >

A wrapper for distributions.

A wrapped for distributions that draws its properties from Parameters. The capabilities provided by this class are almost the same as the random distribution requirements by the standard except it lacks a default constructor.

Template Parameters

Parameters

Must be a class from fcppt::random::distribution::parameters

Public Types
using	distribution_type = basic
	A self typedef required by the standard.
using	wrapped_distribution = typename Parameters::distribution
	The underlying distribution used.
using	result_type = typename Parameters::result_type
	The result type of applying this distribution.
using	param_type = Parameters
	The parameters type, required by the standard.

Public Member Functions
	basic (param_type const &parameters)
	Constructs the distribution from the parameters type.
template<typename T1, typename T2>
	basic (T1 const &p1, T2 const &p2)
	Constructs the distribution from multiple parameters.
void	reset ()
	Resets the underlying distribution.
param_type	param () const
	Returns the parameters used to construct the distribution.
void	param (param_type const &parameters)
	Supplies new parameters to the distribution.
template<typename Rng>
result_type	operator() (Rng &generator)
	Draws a random number.
template<typename Rng>
result_type	operator() (Rng &generator, param_type const &parameters)
	Draws a random number with parameters.
result_type	min () const
	The minimum value that can be produced.

Constructor & Destructor Documentation

basic() [1/2]

template<typename Parameters>

fcppt::random::distribution::basic< Parameters >::basic ( param_type const & parameters )

explicit

Constructs the distribution from the parameters type.

Constructs the distribution from parameters

Parameters

parameters

The parameters to use

basic() [2/2]

template<typename Parameters>

template<typename T1, typename T2>

fcppt::random::distribution::basic< Parameters >::basic	(	T1 const &	p1,
		T2 const &	p2 )

Constructs the distribution from multiple parameters.

Constructs the distribution from p1 and p2, calling param_type(p1,p2)

Note

This should really be replaced by a variadic template

Parameters

p1	The first parameter
p2	The second parameter

Template Parameters

T1	A type compatible to the first parameter of param_type
T2	A type compatible to the second parameter of param_type
