The Permission class for link creation operations.
|
| Paths |
This class consists exclusively of static methods that return a Path
by converting a path string or URI.
|
| SimpleFileVisitor<T> | A simple visitor of files with default behavior to visit all files and to re-throw I/O errors. |
| StandardWatchEventKinds | Defines the standard event kinds. |
Enums
| AccessMode | Defines access modes used to test the accessibility of a file. |
| FileVisitOption | Defines the file tree traversal options. |
| FileVisitResult |
The result type of a FileVisitor.
|
| LinkOption | Defines the options as to how symbolic links are handled. |
| StandardCopyOption | Defines the standard copy options. |
| StandardOpenOption | Defines the standard open options. |
Exceptions
| AccessDeniedException | Checked exception thrown when a file system operation is denied, typically due to a file permission or other access check. |
| AtomicMoveNotSupportedException | Checked exception thrown when a file cannot be moved as an atomic file system operation. |
| ClosedDirectoryStreamException | Unchecked exception thrown when an attempt is made to invoke an operation on a directory stream that is closed. |
| ClosedFileSystemException | Unchecked exception thrown when an attempt is made to invoke an operation on a file and the file system is closed. |
| ClosedWatchServiceException | Unchecked exception thrown when an attempt is made to invoke an operation on a watch service that is closed. |
| DirectoryIteratorException | Runtime exception thrown if an I/O error is encountered when iterating over the entries in a directory. |
| DirectoryNotEmptyException | Checked exception thrown when a file system operation fails because a directory is not empty. |
| FileAlreadyExistsException | Checked exception thrown when an attempt is made to create a file or directory and a file of that name already exists. |
| FileSystemAlreadyExistsException | Runtime exception thrown when an attempt is made to create a file system that already exists. |
| FileSystemException | Thrown when a file system operation fails on one or two files. |
| FileSystemLoopException | Checked exception thrown when a file system loop, or cycle, is encountered. |
| FileSystemNotFoundException | Runtime exception thrown when a file system cannot be found. |
| InvalidPathException |
Unchecked exception thrown when path string cannot be converted into a
Path because the path string contains invalid characters, or
the path string is invalid for other file system specific reasons.
|
| NoSuchFileException | Checked exception thrown when an attempt is made to access a file that does not exist. |
| NotDirectoryException | Checked exception thrown when a file system operation, intended for a directory, fails because the file is not a directory. |
| NotLinkException | Checked exception thrown when a file system operation fails because a file is not a symbolic link. |
| ProviderMismatchException | Unchecked exception thrown when an attempt is made to invoke a method on an object created by one file system provider with a parameter created by a different file system provider. |
| ProviderNotFoundException | Runtime exception thrown when a provider of the required type cannot be found. |
| ReadOnlyFileSystemException |
Unchecked exception thrown when an attempt is made to update an object
associated with a read-only FileSystem.
