basic_path 클래스
Defines a class that stores an object of template type String that's suitable for use as a file name.
template<class String, class Traits>
class basic_path;
설명
The library defines specializations of this template for two types.
basic_path<string, path_traits>, with the typedef path, uses std::string and the path_traits structure.
basic_path<wstring, wpath_traits>, with the typedef wpath, uses std::wstring and the wpath_traits structure.
You can use an object of type path wherever an argument of type std::string is acceptable as a file name.
std::tr2::sys::path myfile(“abc.txt”);
std::ofstream ofs(myfile);
ofs << “hello\n”;
ofs.close();
Similarly, you can use an object of type wpath wherever an argument of type std::wstring is acceptable as a file name.
A stored file name consists of an optional prefix, followed by an optional root, followed by an optional relative path.
A prefix consists of all elements that lead up to and include the first colon.
A root consists of one slash.
A relative path consists of one or more path elements that are delimited by sequences of slashes.
A file name iterator that is returned by basic_path::begin designates the first filename component.
A filename iterator X implies the following.
X == end() indicates the end of the sequence of filename components.
*X returns a string that matches the current component.
++X designates the next component, if present.
--X designates the preceding component, if present.
