> AllOrNothingOutputStream
> ------------------------

> Key: IO-412
> URL: https://issues.apache.org/jira/browse/IO-412
> Project: Commons IO
> Issue Type: New Feature
> Components: Streams/Writers
> Reporter: BELUGA BEHR
> Priority: Minor
> Attachments: AllOrNothingFileOutputStream.java, PartingFileOutputStream.java

> 
> Feel free to include this new FileOutputstream.  No unit tests yet.  Looking for \
> feedback at this point. {code}
> /**
> * This is a wrapper around a FileOutputStream. It enables a stream to be
> * written to a hidden file in a directory and only then renamed to the final
> * destination if no exceptions occur. This implementation marks the file as
> * hidden by pre-appending the file name with a period. If any exceptions occur
> * during writing, the hidden file will be deleted once close() is called. This
> * class takes advantage of {@link File#renameTo(File)}; therefore, many aspects
> * of the behavior of this class are inherently platform-dependent: The rename
> * operation might not be able to move a file from one filesystem to another, it
> * might not be atomic, and it might not succeed if a file with the destination
> * abstract pathname already exists. This class is most useful when the rename
> * operation is atomic. It is designed for the case when one process is writing
> * to a directory and another process is polling the directory for files to
> * read.
