Package java.nio.file.attribute Description

Interfaces and classes providing access to file and 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. Views can be identified by name.

The BasicFileAttribute view defines the basic set of file attributes that are common to many file systems.

In addition to attribute views, this package also defines classes and interfaces that are used when accessing attributes:

• The 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.

Basic Attribute names

A file attribute view that provides a view of a basic set of file attributes common to many file systems. The basic set of file attributes consist of mandatory and optional file attributes as defined below.

The file attributes are retrieved from the file system as a bulk operation by invoking the Files.readAttributes method.

Where dynamic access to file attributes is required, the attributes supported by this attribute view have the following names and types:

Name	Type
"lastModifiedTime"	FileTime
"lastAccessTime"	FileTime
"creationTime"	FileTime
"size"	Long
"isRegularFile"	Boolean
"isDirectory"	Boolean
"isSymbolicLink"	Boolean
"isOther"	Boolean

The getAttribute method may be used to read any of these attributes as if by invoking the Files.readAttributes method.

The setAttribute method may be used to update the file's last modified time, last access time or create time attributes.

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.
