| * |
| * <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> |
| * |
| * <p><li> The {@link java.nio.file.attribute.UserPrincipal} and |
| * {@link java.nio.file.attribute.GroupPrincipal} interfaces represent an |
| * identity or group identity. </li> |
| * |
| * <p><li> The {@link java.nio.file.attribute.UserPrincipalLookupService} |
| * interface defines methods to lookup user or group principals. </li> |
| * |
| * <p><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. |
