## 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.
