示例1: result
basic_parsed_options<charT>
parse_config_file(std::basic_istream<charT>& is,
const options_description& desc,
bool allow_unregistered)
{
set<string> allowed_options;

for (unsigned i = 0; i < options.size(); ++i)
{
const option_description& d = *options[i];
if (d.long_name().empty())
pdalboost::throw_exception(
error("long name required for config file"));
allowed_options.insert(d.long_name());
}
// Parser return char strings
parsed_options result(&desc);

is, allowed_options, allow_unregistered),
detail::basic_config_file_iterator<charT>(),

// Convert char strings into desired type.
return basic_parsed_options<charT>(result);
}示例2: get_section_options
options_description get_section_options(const string section_name, const string group_caption, const options_description &original_options_descriptions)
{
const std::vector< shared_ptr<option_description> >&original_options = original_options_descriptions.options();

// IMPORTANT: in order for this line not to crash the original_options_descriptions needs to be a static declaration
// otherwise t_option.semantic().get() will point to an invalid memory direction and
// the application will raise a segmentation fault
