Interface DosFileAttributeView
- All Superinterfaces:
AttributeView
,BasicFileAttributeView
,FileAttributeView
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 Boolean
hidden Boolean
system Boolean
archive 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.

readAttributes
Description copied from interface:BasicFileAttributeView
Reads the basic file attributes as a bulk operation.It is implementation specific if all file attributes are read as an atomic operation with respect to other file system operations.
- Specified by:
readAttributes
in interfaceBasicFileAttributeView
- Returns:
- the file attributes
- Throws:
IOException
- if an I/O error occurs
-
setReadOnly
Updates the value of the read-only attribute.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.
- Parameters:
value
- the new value of the attribute- Throws:
IOException
- if an I/O error occurs
-
setHidden
Updates the value of the hidden attribute.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.
- Parameters:
value
- the new value of the attribute- Throws:
IOException
- if an I/O error occurs
-
setSystem
Updates the value of the system attribute.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.
- Parameters:
value
- the new value of the attribute- Throws:
IOException
- if an I/O error occurs
-
setArchive
Updates the value of the archive attribute.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.
- Parameters:
value
- the new value of the attribute- Throws:
IOException
- if an I/O error occurs
