inlinevirtualinherited

Does NOT set option name, because no option name makes sense.

void boost::program_options::error_with_option_name::set_substitute ( const std::string &  parameter_name, const std::string &  value  )

inlineinherited

Substitute parameter_name->value to create the error message from the error template.

References boost::program_options::value().
