Recursive directory entry input stream iterator.

Recursive directory entry input stream that ignores all hidden files during traversal and does not recurse to hidden directories.

Recursive directory entry input stream.

FilePred

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

DirPred

directory predicate type, that determines which directories to recurse into.

• File and directory predicates may have internal state.

Base classes

• public sys::basic_idirectory< FilePred >

Types

• 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.

• using dirpred_type = DirPred

  Directory predicate type.

• using iterator = basic_istream_iterator< basic_idirtree, value_type >

Methods

• end() -> iterator
• begin() -> iterator
• num_directories() const -> size_t

  Return the number of directories in the stack.

• next_directory() -> void

  Go to the next directory.

• operator>>(directory_entry & rhs) -> basic_idirtree &

  Get next directory entry as directory_entry.

• setdirpred(dirpred_type rhs) -> void

  Set directory predicate.

• getdirpred() -> dirpred_type &

  Get directory predicate.

• getdirpred() const -> const dirpred_type &

  Get directory predicate.

• current_dir() const -> const path &

  Path to the directory which is currently being traversed.

• open(path_view p) -> void

  Open path p as input directory.

• basic_idirtree(path_view starting_point)explicit

  Construct recursive directory entry input stream for input directory starting_point.

• basic_idirtree()

Do not recurse to hidden directories when traversing directories.

• Default directory predicate for idirtree.
• Caches file status, which is accessed with status method.
• File status is updated only if file system does not return file type in directory_entry.

Methods

• status(const path & p) -> const file_status &

  Get or compute file status.

• has_type() const -> bool

  Returns true if file status was not queried for the current file.

• has_status() const -> bool

  Returns true if file status was queried for the current file.

• status() -> file_status &

  Get file status.

• status() const -> const file_status &

  Get file status.

• operator()(const path & prefix, const directory_entry & rhs) -> bool

  Returns true, if directory entry is not hidden.
