discrete_distribution::operator()

Returns a random value.

template<class Engine>
    result_type operator()(Engine& eng);
template<class Engine>
    result_type operator()(Engine& eng,
        const param_type& par0);

Parameters

• eng
  The random engine.

• par0
  The parameter package used to return the random value.

Remarks

The first member operator uses the engine eng as a source of uniformly distributed random integral values and returns integral values with each value i in the range [0, stored_p.size() - 1) occurring with probability stored_p[i] and all other values of i occurring with probability zero.

The second member function behaves the same, except that it uses the parameters stored in par0.
