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.
