update(fromPath:)
Updates the file wrapper to match a given file-system node.
Declaration
func update(fromPath path: String) -> BoolReturn Value
true if the update is carried out, false if it isn’t needed.
Discussion
For a directory file wrapper, the contained file wrappers are also sent update(fromPath:) messages. If nodes in the corresponding directory on the file system have been added or removed, corresponding file wrappers are released or created as needed.
Special Considerations
Beginning with OS X v10.6, the preferred method of referring to files is with a file:// URL. Therefore, this method has been deprecated in favor of read(from:options:).
