template<class URNG>bool operator()(URNG& g, const param_type& parm);

Generate random number

The generator object (g) supplies uniformly-distributed random integers through its operator() member function. The bernoulli_distribution object transforms the values obtained this way so that successive calls to this member function with the same arguments produce values that follow a Bernoulli distribution with the appropriate probability.

g

A uniform random number generator object, used as the source of randomness.
URNG shall be a uniform random number generator type, such as one of the standard generator classes.

parm

An object representing the distribution's parameters, obtained by a call to member function param.
param_type is a member type.
