directory_entry Class

Describes an object that is returned by *X, where X is a directory_iterator or a recursive_directory_iterator.

Syntax

class directory_entry;

Remarks

The class stores an object of type path. The stored path can be an instance of the path Class or of a type that is derived from path. It also stores two file_type values. One value represents the status of the stored file name. The other represents the symbolic link status of the file name.

For more information and code examples, see File System Navigation (C++).

Constructors

Constructor	Description
directory_entry	The defaulted constructors behave as expected. The fourth constructor initializes mypath to pval, mystat to stat_arg, and mysymstat to symstat_arg.

Member functions

Member function	Description
assign	The member function assigns pval to mypath, stat to mystat, and symstat to mysymstat.
path	The member function returns mypath.
replace_filename	The member function replaces mypath with mypath.parent_path() / pval, mystat with stat_arg, and mysymstat with symstat_arg
status	Both member functions return mystat possibly first altered.
symlink_status	Both member functions return mysymstat possibly first altered.

Operators

Operator	Description
operator!=	Replaces the elements of the list with a copy of another list.
operator=	The defaulted member assignment operators behave as expected.
operator==	Returns mypath == right.mypath.
operator<	Returns mypath < right.mypath.
operator<=	Returns !(right < *this).
operator>	Returns right < *this.
operator>=	Returns !(*this < right).
operator const path_type&	Returns mypath.

Requirements

Header: <experimental/filesystem>

Namespace: std::experimental::filesystem

assign

The member function assigns pval to mypath, stat_arg to mystat, and symstat_arg to mysymstat.

void assign(const std::experimental::filesystem::path& pval,
    file_status stat_arg = file_status(),
    file_status symstat_arg = file_status());

Parameters

pval
The stored file name path.

stat_arg
The status of the stored file name.

symstat_arg
The symbolic link status of the stored file name.

directory_entry

The defaulted constructors behave as expected. The fourth constructor initializes mypath to pval, mystat to stat_arg, and mysymstat to symstat_arg.

directory_entry() = default;
directory_entry(const directory_entry&) = default;
directory_entry(directory_entry&&) noexcept = default;
explicit directory_entry(const std::experimental::filesystem::path& pval,
    file_status stat_arg = file_status(),
    file_status symstat_arg = file_status());

Parameters

pval
The stored file name path.

stat_arg
The status of the stored file name.

symstat_arg
The symbolic link status of the stored file name.

operator!=

The member function returns !(*this == right).

bool operator!=(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator=

The defaulted member assignment operators behave as expected.

directory_entry& operator=(const directory_entry&) = default;
directory_entry& operator=(directory_entry&&) noexcept = default;

Parameters

right
The directory_entry being copied into the directory_entry.

operator==

The member function returns mypath == right.mypath.

bool operator==(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator<

The member function returns mypath < right.mypath.

bool operator<(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator<=

The member function returns !(right < *this).

bool operator<=(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator>

The member function returns right < *this.

bool operator>(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator>=

The member function returns !(*this < right).

bool operator>=(const directory_entry& right) const noexcept;

Parameters

right
The directory_entry being compared to the directory_entry.

operator const path_type&

The member operator returns mypath.

operator const std::experimental::filesystem::path&() const;

path

The member function returns mypath.

const std::experimental::filesystem::path& path() const noexcept;

replace_filename

The member function replaces mypath with mypath.parent_path() / pval, mystat with stat_arg, and mysymstat with symstat_arg

void replace_filename(
    const std::experimental::filesystem::path& pval,
    file_status stat_arg = file_status(),
    file_status symstat_arg = file_status());

Parameters

pval
The stored file name path.

stat_arg
The status of the stored file name.

symstat_arg
The symbolic link status of the stored file name.

status

Both member functions return mystat possibly first altered as follows:

1. If status_known(mystat) then do nothing.

2. Otherwise, if !status_known(mysymstat) && !is_symlink(mysymstat) then mystat = mysymstat.

file_status status() const;
file_status status(error_code& ec) const noexcept;

Parameters

ec
The status error code.

symlink_status

Both member functions return mysymstat possibly first altered as follows: If status_known(mysymstat) then do nothing. Otherwise, mysymstat = symlink_status(mypval).

file_status symlink_status() const;
file_status symlink_status(error_code& ec) const noexcept;

Parameters

ec
The status error code.
