/**@class java.nio.file.attribute.BasicFileAttributeView implements java.nio.file.attribute.FileAttributeView A file attribute view that provides a view of a <em>basic set</em> of file attributes common to many file systems. The basic set of file attributes consist of <em>mandatory</em> and <em>optional</em> file attributes as defined by the {@link java.nio.file.attribute.BasicFileAttributes} interface. <p> The file attributes are retrieved from the file system as a <em>bulk operation</em> by invoking the {@link #readAttributes() readAttributes} method. This class also defines the {@link #setTimes setTimes} method to update the file's time attributes. <p> Where dynamic access to file attributes is required, the attributes supported by this attribute view have the following names and types: <blockquote> <table border="1" cellpadding="8" summary="Supported attributes"> <tr> <th> Name </th> <th> Type </th> </tr> <tr> <td> "lastModifiedTime" </td> <td> {@link java.nio.file.attribute.FileTime} </td> </tr> <tr> <td> "lastAccessTime" </td> <td> {@link java.nio.file.attribute.FileTime} </td> </tr> <tr> <td> "creationTime" </td> <td> {@link java.nio.file.attribute.FileTime} </td> </tr> <tr> <td> "size" </td> <td> {@link Long} </td> </tr> <tr> <td> "isRegularFile" </td> <td> {@link Boolean} </td> </tr> <tr> <td> "isDirectory" </td> <td> {@link Boolean} </td> </tr> <tr> <td> "isSymbolicLink" </td> <td> {@link Boolean} </td> </tr> <tr> <td> "isOther" </td> <td> {@link Boolean} </td> </tr> <tr> <td> "fileKey" </td> <td> {@link Object} </td> </tr> </table> </blockquote> <p> The {@link java.nio.file.Files#getAttribute getAttribute} method may be used to read any of these attributes as if by invoking the {@link #readAttributes() readAttributes()} method. <p> The {@link java.nio.file.Files#setAttribute setAttribute} method may be used to update the file's last modified time, last access time or create time attributes as if by invoking the {@link #setTimes setTimes} method. @since 1.7 */ var BasicFileAttributeView = { /**Returns the name of the attribute view.

The values are converted to the epoch and precision supported by the file system. Converting from finer to coarser granularities result in precision loss. The behavior of this method when attempting to set a timestamp that is not supported or to a value that is outside the range supported by the underlying file store is not defined. It may or not fail by throwing an {@code IOException}. <p> If any of the {@code lastModifiedTime}, {@code lastAccessTime}, or {@code createTime} parameters has the value {@code null} then the corresponding timestamp is not changed. An implementation may require to read the existing values of the file attributes when only some, but not all, of the timestamp attributes are updated. Consequently, this method may not be an atomic operation with respect to other file system operations. Reading and re-writing existing values may also result in precision loss. If all of the {@code lastModifiedTime}, {@code lastAccessTime} and {@code createTime} parameters are {@code null} then this method has no effect. <p> <b>Usage Example:</b> Suppose we want to change a file's last access time. <pre> Path path = ... FileTime time = ... Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null); </pre> @param {Object {FileTime}} lastModifiedTime the new last modified time, or {@code null} to not change the value @param {Object {FileTime}} lastAccessTime the last access time, or {@code null} to not change the value @param {Object {FileTime}} createTime the file's create time, or {@code null} to not change the value @throws IOException if an I/O error occurs @throws SecurityException In the case of the default provider, a security manager is installed, its {@link SecurityManager#checkWrite(String) checkWrite} method is invoked to check write access to the file @see java.nio.file.Files#setLastModifiedTime */ setTimes : function( ) {}, };
