public virtual System.IO.Stream? StartWrite ();

abstract member StartWrite : unit -> System.IO.Stream
override this.StartWrite : unit -> System.IO.Stream

Returns

Stream

Attributes: RegisterAttribute

Exceptions

IOException

Remarks

Start a new write operation on the file. This returns a FileOutputStream to which you can write the new file data. The existing file is replaced with the new data. You <em>must not</em> directly close the given FileOutputStream; instead call either #finishWrite(FileOutputStream) or #failWrite(FileOutputStream).

Note that if another thread is currently performing a write, this will simply replace whatever that thread is writing with the new file being written by this thread, and when the other thread finishes the write the new write operation will no longer be safe (or will be lost). You must do your own threading protection for access to AtomicFile.
