# Class StringBufferWriter

java.lang.Object
java.io.Writer
org.codehaus.groovy.runtime.StringBufferWriter

All Implemented Interfaces:
  `Closeable`, `Flushable`, `Appendable`, `AutoCloseable`

    public class StringBufferWriter
    extends Writer

This class codes around a silly limitation 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.
