PosixFileAttributes
Stay organized with collections

File attributes associated with files on file systems used by operating systems
that implement the Portable Operating System Interface (POSIX) family of
standards.
The POSIX attributes of a file are retrieved using a PosixFileAttributeView by invoking its readAttributes method.

Public Methods
Returns the group owner of the file.
Returns the owner of the file.
Returns the permissions of the file. The file permissions are returned
as a set of PosixFilePermission elements. The returned set is a
copy of the file permissions and is modifiable. This allows the result
to be modified and passed to the setPermissions method to update the file's permissions.
