io - How do you "empty" a StringWriter in Java?

Question

What is the correct way to "empty" a StringWriter in Java so that I can reuse the StringWriter without having to create a new one? Neither StringWriter.flush() nor StringWriter.close() seem to have the desired effect.

How about calling getBuffer().setLength(0)?
