Can I have a more example of FileAttribute?

Question

Basically in the Files.createFile(Path fileName, FileAttribute<?>... attrs ); there is the possibility to insert a series of attributes. I am aware of the following possibility:

Path path = Paths.get(path...);//the file path


PosixFileAttributes attr = Files.readAttributes(path,PosixFileAttributes.class);
Set<PosixFilePermission> permissions = attr.permissions();
FileAttribute<Set<PosixFilePermission>> attra 
                            = PosixFilePermissions.asFileAttribute(permissions);
Files.createFile(path,attra);

Do you know any other real life application of the createFile() method? And with other application I mean other attributes passed as a FileAttribute parameter other than a set of PosixFilePermission? What are other "passable" FileAttribute parameter that I can use to create a new file with File.createFile(path, attr); ? Thanks in advance.

Answer 1

Yes, the Access Control Lists (ACL) attributes.

See Java 7 Documentation for AclFileAttributeView for how to use them with createFile and createDirectory methods.
