## Predefined Constants

`FilesystemIterator::CURRENT_AS_PATHNAME`

  Makes FilesystemIterator::current return the pathname.

`FilesystemIterator::CURRENT_AS_FILEINFO`

  Makes FilesystemIterator::current return an SplFileInfo instance.

`FilesystemIterator::CURRENT_AS_SELF`

  Makes FilesystemIterator::current return $this (the FilesystemIterator).

`FilesystemIterator::CURRENT_MODE_MASK`

  Masks FilesystemIterator::current

`FilesystemIterator::KEY_AS_PATHNAME`

  Makes FilesystemIterator::key return the pathname.

`FilesystemIterator::KEY_AS_FILENAME`

  Makes FilesystemIterator::key return the filename.

`FilesystemIterator::KEY_MODE_MASK`

  Masks FilesystemIterator::key

`FilesystemIterator::NEW_CURRENT_AND_KEY`

  Same as FilesystemIterator::KEY_AS_FILENAME | FilesystemIterator::CURRENT_AS_FILEINFO.

`FilesystemIterator::SKIP_DOTS`

  Skips dot files (. and ..).

`FilesystemIterator::UNIX_PATHS`

  Makes paths use Unix-style forward slash irrespective of system default.
