explicit discrete_distribution( const param_type& params );

Constructs a new distribution object.

1) Default constructor. Constructs the distribution with a single weight p={1}. This distribution will always generate ​0​.

2) Constructs the distribution with weights in the range [first, last). If first == last, the effects are the same as of the default constructor.

3) Constructs the distribution with weights in weights. Effectively calls discrete_distribution(weights.begin(), weights.end()). 4) Constructs the distribution with count weights that are generated using function unary_op. Each of the weights is equal to w.

i = unary_op(xmin + δ/2 + i · δ), where δ =

and i ∈ {0, ..., count−1}. xmin and xmax must be such that δ > 0. If count == 0 the effects are the same as of the default constructor.

5) Constructs the distribution with params as the distribution parameters.
