Class StringBufferWriter

java.lang.Object
java.io.Writer
org.codehaus.groovy.runtime.StringBufferWriter
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable
public class StringBufferWriter
extends java.io.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.
