Method Detail

• isReadOnly

  boolean isReadOnly()

  Returns true to indicate that this archive file system is read-only.

  Overrides:

  Returns:

  true

• mknod

  FsArchiveFileSystemOperation<E> mknod(FsEntryName name,
                                      Entry.Type type,
                                      BitField<FsOutputOption> options,
                                      Entry template)
                                                         throws FsArchiveFileSystemException

  Description copied from class: FsArchiveFileSystem
  Begins a transaction to create or replace and finally link a chain of one or more archive entries for the given path into this archive file system.

  To commit the transaction, you need to call FsArchiveFileSystemOperation.commit() on the returned object, which will mark this archive file system as touched and set the last modification time of the created and linked archive file system entries to the system's current time at the moment of the call to this method.

  Overrides:

  mknod in class FsArchiveFileSystem<E extends FsArchiveEntry>

  Parameters:

  name - the archive file system entry name.

  type - the type of the archive file system entry to create.

  options - if CREATE_PARENTS is set, any missing parent directories will be created and linked into this file system with its last modification time set to the system's current time.

  template - if not null, then the archive file system entry at the end of the chain shall inherit as much properties from this entry as possible - with the exception of its name and type.

  Returns:

  A new archive file system operation on a chain of one or more archive file system entries for the given path name which will be linked into this archive file system upon a call to its FsArchiveFileSystemOperation.commit() method.

  Throws:

  FsArchiveFileSystemException - If one of the following is true:

  • The file system is read only.
  • name contains characters which are not supported by the file system.
  • TODO: type is not FILE or DIRECTORY.
  • The entry already exists and either the option FsOutputOption.EXCLUSIVE is set or the entry is a directory.
  • The entry exists as a different type.
  • A parent entry exists but is not a directory.
  • A parent entry is missing and createParents is false.

• setTime

  boolean setTime(FsEntryName path,
                BitField<Entry.Access> types,
                long value)
            throws FsArchiveFileSystemException

  Overrides:

  setTime in class FsArchiveFileSystem<E extends FsArchiveEntry>

  Throws:

  FsArchiveFileSystemException

• setTime

  boolean setTime(FsEntryName path,
                Map<Entry.Access,Long> times)
            throws FsArchiveFileSystemException

  Overrides:

  setTime in class FsArchiveFileSystem<E extends FsArchiveEntry>

  Throws:

  FsArchiveFileSystemException

• unlink

  void unlink(FsEntryName path)
        throws FsArchiveFileSystemException

  Description copied from class: FsArchiveFileSystem
  Tests the named file system entry and then - unless its the file system root - notifies the listener and deletes the entry. For the file system root, only the tests are performed but the listener does not get notified and the entry does not get deleted. For the tests to succeed, the named file system entry must exist and directory entries (including the file system root) must be empty.

  Overrides:

  unlink in class FsArchiveFileSystem<E extends FsArchiveEntry>

  Parameters:

  path - the archive file system entry name.

  Throws:

  FsReadOnlyArchiveFileSystemException - If this (virtual) archive file system is read-only.

  FsArchiveFileSystemException - If the operation fails for some other reason.
