 public interface DosFileAttributeView extends BasicFileAttributeView A file attribute view that provides a view of the legacy "DOS" file attributes. These attributes are supported by file systems such as the File Allocation Table (FAT) format commonly used in consumer devices.A DosFileAttributeViewis aBasicFileAttributeViewthat 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 BooleanThe getAttributemethod may be used to read any of these attributes, or any of the attributes defined byBasicFileAttributeViewas if by invoking thereadAttributes()method.The setAttributemethod may be used to update the file's last modified time, last access time or create time attributes as defined byBasicFileAttributeView. It may also be used to update the DOS attributes as if by invoking thesetReadOnly,setHidden,setSystem, andsetArchivemethods respectively.- Since:

Method Detail- 
nameString name() Returns the name of the attribute view. Attribute views of this type have the name"dos".- Specified by:
- namein interface- AttributeView
- Specified by:
- namein interface- BasicFileAttributeView
- Returns:
- the name of the attribute view

readAttributesDosFileAttributes readAttributes() throws IOException Description copied from interface:BasicFileAttributeViewReads 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:
- readAttributesin interface- BasicFileAttributeView
- Returns:
- the file attributes
- Throws:
- IOException- if an I/O error occurs
- SecurityException- In the case of the default provider, a security manager is installed, its- checkReadmethod is invoked to check read access to the file
 
 - 
setReadOnlyvoid setReadOnly(boolean value) throws IOExceptionUpdates 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
- SecurityException- In the case of the default, and a security manager is installed, its- checkWritemethod is invoked to check write access to the file
 
 - 
setHiddenvoid setHidden(boolean value) throws IOExceptionUpdates 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
- SecurityException- In the case of the default, and a security manager is installed, its- checkWritemethod is invoked to check write access to the file
 
 - 
setSystemvoid setSystem(boolean value) throws IOExceptionUpdates 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
- SecurityException- In the case of the default, and a security manager is installed, its- checkWritemethod is invoked to check write access to the file
 
 - 
setArchivevoid setArchive(boolean value) throws IOExceptionUpdates 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
- SecurityException- In the case of the default, and a security manager is installed, its- checkWritemethod is invoked to check write access to the file
