• mknod

  public 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.run() 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.run() 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.

• unlink

  public void unlink(FsEntryName path)
              throws FsArchiveFileSystemException

  Description copied from class: FsArchiveFileSystem
  If this method returns, the file system entry identified by the given path has been successfully deleted from this archive file system. If the file system entry is a directory, it must be empty for successful deletion.

  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.

                BitField<Entry.Access> types,
                long value)
