public class AsyncMessageOutputPlus extends AsyncChannelOutputPlus
DataOutputStreamPlus that writes ASYNCHRONOUSLY to a Netty Channel.
Intended as single use, to write one (large) message.
The close() and flush() methods synchronously wait for pending writes, and will propagate any exceptions
encountered in writing them to the wire.
The correctness of this class depends on the ChannelPromise we create against a Channel always being completed,
which appears to be a guarantee provided by Netty so long as the event loop is running.AsyncChannelOutputPlus.FlushExceptionbuffer| Modifier and Type | Method and Description |
|---|---|
void |
close()
Flush any remaining writes, and release any buffers.

discard()
Discard any buffered data, and the buffers that contain it.

Returns the current position of the underlying target like a file-pointer
or the position withing a buffer.
