Detailed Description

The AtomicFileRetriever tries to replace target files in one (nearly) "atomic" rename operation after file close.

This is useful for replacing files where you have to guarantee that they are consistant at any time.

If the target file exists AtomicFileRetriever will try to set the same permissions on the newly created file.
