All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable

public class StringBufferWriter
extends java.io.Writer

This class codes around a silly limiation of StringWriter which doesn't allow a StringBuffer to be passed in as a constructor for some bizarre reason. So we replicate the behaviour of StringWriter here but allow a StringBuffer to be passed in.
