template<typename CharT, typename Traits> 
   
  ( os, 
              param);

Writes the parameters to a std::ostream.

template<typename CharT, typename Traits> 
   
  ( is, 
              param);

Reads the parameters from a std::istream.

 ( lhs,  rhs);

Returns true if the two sets of parameters are the same.

 ( lhs,  rhs);

Returns true if the two sets of parameters are different.

();

Constructs a param_type object, representing a distribution that produces values uniformly distributed in the range [0, 1).

template<typename IntervalIter, typename WeightIter> 
  ( intervals_first,  intervals_last, 
              weight_first);

Constructs a param_type object from two iterator ranges containing the interval boundaries and weights at the boundaries. If there are fewer than two boundaries, then this is equivalent to the default constructor and the distribution will produce values uniformly distributed in the range [0, 1).

The values of the interval boundaries must be strictly increasing, and the number of weights must be the same as the number of interval boundaries. If there are extra weights, they are ignored.

template<typename T, typename F> 
  ( il,  f);

Constructs a param_type object from an initializer_list containing the interval boundaries and a unary function specifying the weights at the boundaries. Each weight is determined by calling the function at the corresponding point.

If the initializer_list contains fewer than two elements, this is equivalent to the default constructor and the distribution will produce values uniformly distributed in the range [0, 1).

template<typename IntervalRange, typename WeightRange> 
  ( intervals_arg, 
              weights_arg);

Constructs a param_type object from Boost.Range ranges holding the interval boundaries and the weights at the boundaries. If there are fewer than two interval boundaries, this is equivalent to the default constructor and the distribution will produce values uniformly distributed in the range [0, 1). The number of weights must be equal to the number of interval boundaries.

template<typename F> 
  ( nw,  xmin,  xmax,  f);

Constructs the parameters for a distribution that approximates a function. The range of the distribution is [xmin, xmax). This range is divided into nw equally sized intervals and the weights are found by calling the unary function f on the boundaries of the intervals.

 () ;

Returns a vector containing the interval boundaries.

 () ;

Returns a vector containing the probability densities at all the interval boundaries.
