    \class QDirListing
    \inmodule QtCore
    \ingroup  io
    \brief The QDirListing class provides an STL-style iterator for directory entries.
 
    You can use QDirListing to navigate entries of a directory one at a time.
    It is similar to QDir::entryList() and QDir::entryInfoList(), but because
    it lists entries one at a time instead of all at once, it scales better
    and is more suitable for large directories. It also supports listing
    directory contents recursively, and following symbolic links. Unlike
    QDir::entryList(), QDirListing does not support sorting.
 
    The QDirListing constructor takes a directory path string as
    argument. Here's how to iterate over all entries recursively:
 
    \snippet code/src_corelib_io_qdirlisting.cpp 0
 
    Here's how to find and read all regular files filtered by name, recursively:
 
    \snippet code/src_corelib_io_qdirlisting.cpp 1
 
    Here's how to list only regular files, recursively:
    \snippet code/src_corelib_io_qdirlisting.cpp 5
 
    Here's how to list only regular files and symbolic links to regular
    files, recursively:
    \snippet code/src_corelib_io_qdirlisting.cpp 6
 
//! [std-input-iterator-tag]
    QDirListing::const_iterator models C++20
    \l{https://en.cppreference.com/w/cpp/iterator/input_iterator}{std::input_iterator},
    that is, it is a move-only, forward-only, single-pass iterator, that
    doesn't allow random access.
//! [std-input-iterator-tag]
    It can be used in ranged-for loops (or with C++20 range algorithms that don't
    require random access iterators). Dereferencing a valid iterator returns
    a QDirListing::DirEntry object. The (c)end() sentinel marks the end of
    the iteration. Dereferencing an iterator that is equal to \l{sentinel} is
    undefined behavior.
 
    QDirListing::DirEntry offers a subset of QFileInfo's API (for example,
    fileName(), filePath(), exists()). Internally, DirEntry only constructs
    a QFileInfo object if needed, that is, if the info hasn't been already
    fetched by other system functions. You can use DirEntry::fileInfo()
    to get a QFileInfo. For example:
 
    \snippet code/src_corelib_io_qdirlisting.cpp 3
    \snippet code/src_corelib_io_qdirlisting.cpp 4
 
    \sa QDir, QDir::entryList()

/*! \enum QDirListing::IteratorFlag
 
    This enum class describes flags that can be used to configure the behavior
    of QDirListing. Values from this enumerator can be bitwise OR'ed together.
 
    \value Default
        List all entries, that is, files, directories, symbolic links including broken
        symbolic links (where the target doesn't exist) and special (\e other) system
        files, see ExcludeOther for details.
        Hidden files and directories and the special entries \c{.} and \c{..}
        aren't listed by default.
 
    \value ExcludeFiles
        Don't list regular files. When combined with ResolveSymlinks, symbolic
        links to regular files will be excluded too.
 
    \value ExcludeDirs
        Don't list directories. When combined with ResolveSymlinks, symbolic
        links to directories will be excluded too.
 
    \omitvalue ExcludeSpecial
    \value ExcludeOther [since 6.10]
        Don't list file system entries that are \e not directories, regular files,
        or symbolic links.
        \list
            \li On Unix, a special (other) file system entry is a FIFO, socket,
                character device, or block device. For more details see the
                \l{https://pubs.opengroup.org/onlinepubs/9699919799/functions/mknod.html}{\c mknod}
                manual page.
            \li On Windows (for historical reasons) \c .lnk files are considered
                special (other) file system entries.
        \endlist
 
    \value ResolveSymlinks
        Filter symbolic links based on the type of the target of the link,
        rather than the symbolic link itself. Broken symbolic links (where
        the target doesn't exist) are excluded, set IncludeBrokenSymlinks
        to include them.
        This flag is ignored on operating systems that don't support symbolic links.
 
    \value IncludeBrokenSymlinks [since 6.11]
        Lists broken symbolic links, where the target doesn't exist, regardless
        of the status of the ResolveSymlinks flag.
        This flag is ignored on operating systems that don't support symbolic links.
 
    \value FilesOnly
        Only regular files will be listed. When combined with ResolveSymlinks,
        symbolic links to files will also be listed.
 
    \value DirsOnly
        Only directories will be listed. When combined with ResolveSymlinks,
        symbolic links to directories will also be listed.
 
    \value IncludeHidden
        List hidden entries. When combined with Recursive, the iteration will
        recurse into hidden sub-directories as well.
 
    \value IncludeDotAndDotDot
        List the \c {.} and \c{..} special entries.
 
    \value CaseSensitive
        The file glob patterns in the name filters passed to the QDirListing
        constructor, will be matched case sensitively (for details, see
        QDir::setNameFilters()).
 
    \value Recursive
        List entries inside all sub-directories as well. When combined with
        FollowDirSymlinks, symbolic links to directories will be iterated too.
 
    \value FollowDirSymlinks
        When combined with Recursive, symbolic links to directories will be
        iterated too. Symbolic link loops (e.g., link => . or link => ..) are
        automatically detected and ignored.
 
    \omitvalue NoNameFiltersForDirs

    has since been advanced), the only valid operations on such an object
    are destruction and assignment of a new iterator. Therefore the

    Dereferencing a valid QDirListing::const_iterator returns a DirEntry
    object.
 
    DirEntry offers a subset of QFileInfo's API (for example, fileName(),
    filePath(), exists()). Internally, DirEntry only constructs a QFileInfo
    object if needed, that is, if the info hasn't been already fetched
    by other system functions. You can use DirEntry::fileInfo() to get a
    QFileInfo. For example:
 
    \snippet code/src_corelib_io_qdirlisting.cpp 3
 
    \snippet code/src_corelib_io_qdirlisting.cpp 4
