	*
	* <p> An attribute view provides a read-only or updatable view of the non-opaque
	* values, or <em>metadata</em>, associated with objects in a file system.
	* The {@link java.nio.file.attribute.FileAttributeView} interface is
	* extended by several other interfaces that that views to specific sets of file
	* attributes. {@code FileAttributeViews} are selected by invoking the {@link
	* java.nio.file.Files#getFileAttributeView} method with a
	* <em>type-token</em> to identify the required view. Views can also be identified
	* by name. The {@link java.nio.file.attribute.FileStoreAttributeView} interface
	* provides access to file store attributes. A {@code FileStoreAttributeView} of
	* a given type is obtained by invoking the {@link
	* java.nio.file.FileStore#getFileStoreAttributeView} method.
	*
	* <p> The {@link java.nio.file.attribute.BasicFileAttributeView}
	* class defines methods to read and update a <em>basic</em> set of file
	* attributes that are common to many file systems.
	*
	* <p> The {@link java.nio.file.attribute.PosixFileAttributeView}
	* interface extends {@code 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.
	*
	* <p> The {@link java.nio.file.attribute.DosFileAttributeView}
	* class extends {@code 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.
	*
	* <p> The {@link java.nio.file.attribute.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 <a href="http://www.ietf.org/rfc/rfc3530.txt">
	* <i>RFC 3530: Network File System (NFS) version 4 Protocol</i></a>.
	*
	* <p> In addition to attribute views, this package also defines classes and
	* interfaces that are used when accessing attributes:
	*
	* <ul>
	*
	* <li> The {@link java.nio.file.attribute.UserPrincipal} and
	* {@link java.nio.file.attribute.GroupPrincipal} interfaces represent an
	* identity or group identity. </li>
	*
	* <li> The {@link java.nio.file.attribute.UserPrincipalLookupService}
	* interface defines methods to lookup user or group principals. </li>
	*
	* <li> The {@link java.nio.file.attribute.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. </li>
	*
	* </ul>
	*
	*
	* <p> Unless otherwise noted, passing a <tt>null</tt> argument to a constructor
	* or method in any class or interface in this package will cause a {@link
	* java.lang.NullPointerException NullPointerException} to be thrown.
	*
