> It would be very helpful to have to {{toInputStream()}} method on the 
> {{DeferredFileOutputStream}} class. Besides for convenience, it would allow 
> for improved efficiency since in the case of in-memory data the byte buffer 
> would not need to be copied (as opposed to the current {{getData()}} method). 
> The implementation is pretty simple and can be something like the following 
> (based on the current {{writeTo(OutputStream)}} method):
> {code:java}
> public InputStream toInputStream() throws IOException {
>     if (!closed) {
>         throw new IOException("Stream not closed");
>     }
>     if (isInMemory()) {
>         return memoryOutputStream.toInputStream();
>     } else {
>         return Files.newInputStream(outputFile.toPath());
>     }
> }
> {code}
