Public Methods
public
abstract
boolean
isArchive
()
Returns the value of the archive attribute.
This attribute is typically used by backup programs.
Returns
- the value of the archive attribute
public
abstract
boolean
isHidden
()
Returns the value of the hidden attribute.
This attribute is often used to indicate if the file is visible to
users.
Returns
- the value of the hidden attribute
public
abstract
boolean
isReadOnly
()
Returns the value of the read-only attribute.
This attribute is often used as a simple access control mechanism
to prevent files from being deleted or updated. Whether the file system
or platform does any enforcement to prevent read-only files
from being updated is implementation specific.
Returns
- the value of the read-only attribute
public
abstract
boolean
isSystem
()
Returns the value of the system attribute.
This attribute is often used to indicate that the file is a component
of the operating system.
Returns
- the value of the system attribute
