param_type
public
construct/copy/destructexplicit param_type(RealType m = 0.0, RealType s = 1.0);
Constructs the parameters of a lognormal_distribution
.
param_type
friend functionstemplate<typename CharT, typename Traits> friend std::basic_ostream< CharT, Traits > & operator<<(std::basic_ostream< CharT, Traits > & os, const param_type & param);
Writes the parameters to a std::ostream.
template<typename CharT, typename Traits> friend std::basic_istream< CharT, Traits > & operator>>(std::basic_istream< CharT, Traits > & is, const param_type & param);
Reads the parameters from a std::istream.
friend bool operator==(const param_type & lhs, const param_type & rhs);
Returns true if the two sets of parameters are equal.
friend bool operator!=(const param_type & lhs, const param_type & rhs);
Returns true if the two sets of parameters are different.
