🔗
void clear() noexcept;
1
#
Postconditions: empty() is true.
🔗
path& make_preferred();
2
#
Effects: Each directory-separator of the pathname in the generic format is converted to preferred-separator.
3
#
Returns: *this.
4
#
[Example 1: path p("foo/bar"); std::cout << p << '\n'; p.make_preferred(); std::cout << p << '\n';
On an operating system where preferred-separator is a slash, the output is: "foo/bar" "foo/bar"
On an operating system where preferred-separator is a backslash, the output is: "foo/bar" "foo\bar"
— end example]
🔗
path& remove_filename();
5
#
Effects: Remove the generic format pathname of filename() from the generic format pathname.
6
#
Postconditions: !has_filename().
7
#
Returns: *this.
8
#
[Example 2: path("foo/bar").remove_filename(); // yields "foo/" path("foo/").remove_filename(); // yields "foo/" path("/foo").remove_filename(); // yields "/" path("/").remove_filename(); // yields "/" — end example]
🔗
path& replace_filename(const path& replacement);
9
#
Effects: Equivalent to: remove_filename(); operator/=(replacement);
10
#
Returns: *this.
11
#
[Example 3: path("/foo").replace_filename("bar"); // yields "/bar" on POSIX path("/").replace_filename("bar"); // yields "/bar" on POSIX — end example]
🔗
path& replace_extension(const path& replacement = path());
12
#
Effects:
  • (12.1)
    Any existing extension() ([fs.path.decompose]) is removed from the pathname in the generic format, then
  • (12.2)
    If replacement is not empty and does not begin with a dot character, a dot character is appended to the pathname in the generic format, then
  • (12.3)
    operator+=(replacement);.
13
#
Returns: *this.
🔗
void swap(path& rhs) noexcept;
14
#
Effects: Swaps the contents (in all formats) of the two paths.
15
#
Complexity: Constant time.
