AttributeView, BasicFileAttributeView, FileAttributeView
public interface DosFileAttributeView extends BasicFileAttributeView
A DosFileAttributeView is a BasicFileAttributeView that additionally supports access to the set of DOS attribute flags that are used to indicate if the file is read-only, hidden, a system file, or archived.
Where dynamic access to file attributes is required, the attributes supported by this attribute view are as defined by
BasicFileAttributeView, and in addition, the following attributes are supported:
Name Type readonly Booleanhidden Booleansystem Booleanarchive Boolean
The getAttribute method may be used to read any of these attributes, or any of the attributes defined by BasicFileAttributeView as if by invoking the readAttributes() method.
The setAttribute method may be used to update the file's last modified time, last access time or create time attributes as defined by BasicFileAttributeView. It may also be used to update the DOS attributes as if by invoking the setReadOnly, setHidden, setSystem, and setArchive methods respectively.

BasicFileAttributeViewIt is implementation specific if all file attributes are read as an atomic operation with respect to other file system operations.

It is implementation specific if the attribute can be updated as an atomic operation with respect to other file system operations. An implementation may, for example, require to read the existing value of the DOS attribute in order to update this attribute.
