org.eclipse.rse.files.ui.resources.SystemSafeFileOutputStream
-
All Implemented Interfaces:
-
Closeable,
Flushable
-
public class SystemSafeFileOutputStream
- extends
OutputStream
This class should be used when there's a file already in the
destination and we don't want to lose its contents if a
failure writing this stream happens.
Basically, the new contents are written to a temporary location.
If everything goes OK, it is moved to the right place.
The user has the option to define the temporary location or
it will be created in the default-temporary directory
