public void flush() throws java.io.IOException
Flushing the stream after close()
has been called will cause an
exception to be thrown.
Implementation note: In the current implementation, this is a
no-op. Flushing is left to the underlying stream(s). Note that when
programming against/with this class, always follow good practice and call
flush
.

Once the stream has been closed, further write
or
flush()
invocations will cause an IOException
to be
thrown. Closing a previously closed stream has no effect.
