Attachment: (was: PartingFileOutputStream.java)

> ------------------------
>
> 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, PartingFileOutputStreamTest.java

>
> Feel free to include this new FileOutputstream. No unit tests yet. Looking
> for feedback at this point.

> /**
> * 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.
