## org.codehaus.groovy.runtime
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 limiation of StringWriter which doesn't allow a StringBuffer to be passed in as a constructor for some bizzare reason. So we replicate the behaviour of StringWriter here but allow a StringBuffer to be passed in.
