An attribute view provides a read-only or updatable view of the non-opaque
values, or metadata, associated with objects in a file system.
FileAttributeView interface is
extended by several other interfaces that that views to specific sets of file
FileAttributeViews are selected by invoking the
Files.getFileAttributeView(java.nio.file.Path, java.lang.Class<V>, java.nio.file.LinkOption...) method with a
type-token to identify the required view. Views can also be identified
by name. The

class defines methods to read and write the Access Control List (ACL)
file attribute. The ACL model used by this file attribute view is based
on the model defined by
RFC 3530: Network File System (NFS) version 4 Protocol.
In addition to attribute views, this package also defines classes and interfaces that are used when accessing attributes:
GroupPrincipalinterfaces represent an identity or group identity.
UserPrincipalLookupServiceinterface defines methods to lookup user or group principals.
FileAttributeinterface represents the value of an attribute for cases where the attribute value is required to be set atomically when creating an object in the file system.
Unless otherwise noted, passing a null argument to a constructor
or method in any class or interface in this package will cause a
NullPointerException to be thrown.
