public class IoBufferWrapper extends IoBuffer
IoBuffer
that wraps a buffer and proxies any operations to it.
You can think this class like a FilterOutputStream
. All operations
are proxied by default so that you can extend this class and override existing
operations selectively. You can introduce new operations, too.
