Attribute views Description AttributeViewCan read or update non-opaque values associated with objects in a file system FileAttributeViewCan read or update file attributes BasicFileAttributeViewCan read or update a basic set of file attributes PosixFileAttributeViewCan read or update POSIX defined file attributes DosFileAttributeViewCan read or update FAT file attributes FileOwnerAttributeViewCan read or update the owner of a file AclFileAttributeViewCan read or update Access Control Lists UserDefinedFileAttributeViewCan read or update user-defined file attributes FileStoreAttributeViewCan read or update file system attributes 
 An attribute view provides a read-only or updatable view of the non-opaque
 values, or metadata, associated with objects in a file system.
 The FileAttributeView interface is
 extended by several other interfaces that that views to specific sets of file
 attributes. 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 FileStoreAttributeView interface
 provides access to file store attributes. A FileStoreAttributeView of
 a given type is obtained by invoking the FileStore.getFileStoreAttributeView(java.lang.Class<V>) method.
 
 The BasicFileAttributeView
 class defines methods to read and update a basic set of file
 attributes that are common to many file systems.
 
 The PosixFileAttributeView
 interface extends BasicFileAttributeView by defining methods
 to access the file attributes commonly used by file systems and operating systems
 that implement the Portable Operating System Interface (POSIX) family of
 standards.
 
 The DosFileAttributeView
 class extends BasicFileAttributeView by defining methods to
 access the legacy "DOS" file attributes supported on file systems such as File
 Allocation Tabl (FAT), commonly used in consumer devices.
 
 The AclFileAttributeView
 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:
UserPrincipal and
   GroupPrincipal interfaces represent an
   identity or group identity. UserPrincipalLookupService
   interface defines methods to lookup user or group principals. FileAttribute interface
   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.
