Interface MemoryFileAttributeView

All Superinterfaces:

AttributeView, BasicFileAttributeView, FileAttributeView

public interface MemoryFileAttributeView
extends BasicFileAttributeView

A file attribute view that provides a view of the in-memory file attributes.

A MemoryFileAttributeView is a BasicFileAttributeView that additionally supports access to the set of in-memory attribute flags that are used to indicate if the file is read-only, or hidden.

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	Boolean
hidden	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 in-memory attributes as if by invoking the setReadOnly, and setHidden methods respectively.
