Directory entry input stream that ignores all hidden files during traversal.

Alias to DIR system type.

Directory entry input stream iterator.

Directory entry input stream.

FilePred

file predicate type, that determines which directory entries to include in the stream.

• File predicate may have internal state.

Base classes

• public sys::dirstream

Derived classes

• sys::basic_directory< FilePred, Trans >
• sys::basic_idirtree< FilePred, DirPred >

Types

• using iterator = basic_istream_iterator< basic_idirectory, value_type >

  Directory entry stream iterator.

• using const_pointer = const value_type *

  Directory entry constant pointer.

• using pointer = value_type *

  Directory entry pointer.

• using const_reference = const value_type &

  Directory entry constant reference.

• using reference = value_type &

  Directory entry reference.

• using value_type = directory_entry

  Directory entry type.

• using filepred_type = FilePred

  File predicate type.

Methods

• owner(uid_type uid, gid_type gid, path_flag flags = path_flag(0)) -> void

  Set directory owner.

• end() -> iterator
• begin() -> iterator
• operator>>(reference rhs) -> basic_idirectory &

  Get next directory entry as directory_entry.

• fd() const -> fd_type
• getpath() const -> const path &

  Get input directory.

• setfilepred(filepred_type rhs) -> void

  Set file predicate. This method allows for file predicate to have internal state, that affects which entries are included in the stream.

• getfilepred() const -> const filepred_type &

  Get file predicate.

• is_open() const -> bool

  Returns true, if the directory was opened.

• close() -> void

  Close input directory.

  See

  closedir(3)

• open(path_view p) -> void

  Open directory p as input directory for reading entries.

  See

  opendir(3)

• ~basic_idirectory()
• basic_idirectory(const basic_idirectory &)
• basic_idirectory(basic_idirectory && rhs)

  Move-constructor.

• basic_idirectory(path_view path)explicit

  Construct directory entry input stream for directory path.

• basic_idirectory()

Do not include hidden file when traversing directories. This is the default file predicate for idirectory.

Methods

• template <class Entry>
operator()(const path &, const Entry & rhs) const -> bool

  Returns true, if directory entry rhs is not hidden.
