public class AtomicFileOutputStream
extends FilterOutputStream

A FileOutputStream that has the property that it will only show up at its destination once it has been entirely written and flushed to disk. While being written, it will use a .tmp suffix. When the output stream is closed, it is flushed, fsynced, and will be moved into place, overwriting any file that already exists at that location. NOTE: on Windows platforms, it will not atomically replace the target file - instead the target file is deleted before this one is moved into place.
