@API(status=STABLE,
     since="0.1.0")
public static class IOUtils.NullAppendable
extends Object
implements Appendable

This implementation of an Appendable just swallows any data that is written to it, like the /dev/null device of a Unix or Linux machine, or NUL: on Windows. This class might be useful if an Appendable is required from the API, but not applicable from the application logic.
